Tick Check 1.2.3.

Just last week we posted a pretty good rundown on what to do about ticks—and how. So if you need a review, just call up “Tick, Tack, Toe the Line: Lyme Disease and What to Do” and carry on from there. Remember, the basic idea is no matter which life stage they’re at, know how to protect yourself. Because you can’t count on feeling them crawling on you.

And speaking of life cycles—OK, so the blacklegged tick’s larvae have finished, the nymphs are mostly dormant right now, and the adults have yet to strut their stuff. But that’s no reason to let down your guard. If you’ve been following our posts, you know that there’s a new tick in town (and if you’re following the news, another waiting in the wings.) Their life-cycles can be different. Be watchful!

So here’s what you do:

Two years. Yup. Ticks know how to make good use of their time.

Steer clear of hitchhikers. Ticks don’t survive long in most homes because of low humidity, but still—you’re safest if you put your clothes in a clothes dryer and run it on high heat for 20 minutes. The tumbling action of the dryer and the high heat kill ticks and similar critters.

Wear tick-killing clothing. Information on proper application of permethrin can be found on our post “Minimize tick risk while minimizing pesticide risk.” Also consider buying pretreated cloths or sending your outdoor socks, pants, and shirts for professional treatments.

(Permethrin is an insecticide in the pyrethroid family. Pyrethroids are synthetic chemicals that act like natural extracts from the chrysanthemum flower. BTW, plants can’t run—that’s why many have evolved chemical means of protection. So say I went the DIY route, soaked some mums in oil, put the oil in a spray bottle, and spritzed my pants. But it failed to repel or kill ticks the ticks I bumped up against. Why? Mums come with a cocktail of natural chemicals inside those lovely flowers. And for permethrin and thus for repelling and killing ticks, I’d need to have the right chemicals in my brew—not to mention the know-how for making the stuff.)

Here’s your full-on tick check. Did we say to be thorough? Well, we’re saying it now.

Check for ticks. It bears repeating. Do a tick check at least once a day. Get to know the spots and bumps on your skin so you can recognize new ones. New ones that just happen to have legs.

Protect your pets. Just like people, pets can encounter ticks and acquire tick-borne disease. They can also bring ticks inside with them, which might expose you to ticks. So if your pet goes outdoors, it should have some protection against ticks. Ask your vet. And give it a tick check too—every day.

Remove ticks safely. Only one method has been officially evaluated for its ability to safely remove ticks — using sharp tweezers, grab a tick as close to the skin as possible and gently pull up. Other methods could increase the risk of acquiring a tick-borne disease. To learn more, see our post “It’s tick season. Put away the matches.

Swimming or bathing won’t kill ticks, whether attached or not.

Ticks have a different system of breathing than humans. You can immerse them in water for hours and they won’t croak. Besides, swimming or bathing might not be enough to remove an unattached tick crawling on your body. The best way to kill a tick? Remove it safely with pointy tweezers, then place in a jar of rubbing alcohol.

And there you have it. If we don’t see you at our statewide conference Breaking the Cycle: Integrated Management of Ticks and Mosquitoes on August 7 (9 AM at the Westchester County Center, 198 Central Ave, White Plains, New York), we’ll have a video of the conference uploaded on our website soon after.

It’s not too late to register. Open to the public!

And, as always, we have more Tick Information on our DON’T GET TICKED NEW YORK homepage

Tick, Tack, Toe the Line: Lyme Disease and What to Do

You’ve all heard about them, right? Yeah, the little buggers sneak up on you, bite you, and—maybe—make you sick. Sometimes really sick.

They’re not really bugs, of course, but tiny eight-legged critters remotely related to spiders but without the benefits spiders provide. (Note that adult females plump up like small grapes once they’ve satisfied their appetite.)

Just for fun, I wrote a sentence on my finger — period and all. And yep, the larvae are that small. (Courtesy Cal Dept Public Health)

For today, we’re considering blacklegged ticks, aka the deer tick—the name it was christened with years ago, before entomologists realized that tick is already here; has been for thousands of years—and it already has a name. Yes, we’ve got a couple of other ticks we can’t ignore. But that’s for another day.

So … the best reason for ditching the name “deer tick”? It suggests deer are the problem. OK, blacklegged ticks do infest deer and deer can travel widely, so yes, they carry them around in the literal sense and ticks will drop off here, there, most anywhere. But no, deer don’t vector (aka “carry”) Lyme disease. Look to mice, chipmunks, and shrews for that.

So. Back to the topic at hand. The youngest ticks are six-legged larvae, the size of the period at the end of this sentence—and with one exception, they don’t vector disease. (More on that in another post.) After they feed on, say, a mouse or robin, they morph into nymphs and grow as large as poppy seeds. Since poppy seeds with legs are still darn small, they’re the ones that most often nail us.

And the adults? They’re more likely to vector Lyme and the co-infections that too often accompany it or act in its stead. After all, ticks have adapted to be secretive; to keep from being detected. But since by now they’re the size of sesame seeds—still small, yes, but easier to see—you’re more likely to get shed of them before they do damage.

No matter which life stage they’re at, know how to protect yourself. Because you can’t count on feeling them crawling on you. Here’s the countdown:

Tick habitat—it’s everywhere.

Recognize and avoid tick habitat. Tick species differ in where they prefer to hang out, but it’s possible to come too close for comfort to a tick anytime you leave the pavement. Sure, some parts of the state are home to orders of magnitude more ticks than others are, but that’s no reason to think you’re immune to those nasty little critters catching you unawares. And it’s so easy to be unaware.

Daily Tick Check! Regardless how careful you are, you won’t manage to steer clear of ticks 100 percent of the time. Perform daily tick checks even if you haven’t been outdoors in a day or so. Get to know the spots and bumps on your skin so you can recognize new ones. New ones that just happen to have legs.

Dress the part. If you’ll be in tick habitat (meaning you step off the pavement), take precautions by wearing light-colored, long pants tucked into your socks and a light-colored shirt tucked into pants. It’ll be easier to see ticks crawling on you and more difficult for ticks to get to your skin.

Get yourself some super-pointy tweezers, the type that airport security would probably confiscate. Be firm: steady and straight up until that sucker lets go.

Use repellents. Here’s more on choosing the right repellent.  and this guide from Consumer Reports.

Remove ticks safely. Only one method has been officially evaluated for its ability to safely remove ticks — using sharp tweezers, grab a tick as close to the skin as possible and gently pull up. Other methods could increase the risk of acquiring a tick-borne disease. To learn more, see “It’s tick season. Put away the matches.

Which is all we’ll say for now, other than on August 7 we’re hosting a statewide conference on—you guessed it—ticks. Oh … and skeeters, too:

Comments Off on Tick Trickery

Tick Trickery

Got ticks on your mind? Your questions. Our answers:

How common are tick-borne diseases — and who is at risk?

Lyme disease is the second most common infectious disease in the entire U.S. But over 96% of all cases come from only 14 states. Now that’s scary, because New York and the Northeast are at dead center for tick trickery.

What looks like spilled ink? That’s where most ticks hang out. (CDC)

Indeed, Lyme disease is the most common vector-borne disease in the entire United States — and the second disease most commonly reported to the Centers of Disease Control, aka the CDC. (It comes right after chlamydia and before gonorrhea—both sexually transmitted diseases that could strike most anywhere.)

Each year, the CDC gets reports of about 30,000 cases of Lyme disease. But most likely that’s just a fraction of the number of cases. The CDC estimates that each year between 300,000 and 400,000 people are infected with the bacteria causing Lyme — and children ages 5 to 9 have the greatest risk. Parents, check your kids for ticks every day. Make it as mandatory as brushing teeth. “Oh, they were outside for only 10 minutes” or “Oh, but we live in a big city. How could there ticks possibly be here?” — trust us, these aren’t reasons to skip.

Those numbers on the left-hand side? It’s 5-9 year-old boys who most often run into the wrong side of a tick. (CDC)

No, you don’t have to be an outdoor adventurer to be exposed to disease. People can chance upon ticks in all sorts of places. Pushing a friend on the swings, gardening, picnicking at the park, taking a shortcut through a vacant lot, raking leaves—any perfectly normal activity could put you or your kids on the wrong side of a tick.

What diseases do ticks transmit?

Lyme disease is hardly the only pathogen ticks carry. They can also carry anaplasmosis, babesiosis, erhrlichiosis, Powassan virus, Rocky Mountain spotted fever, tularemia, and Borrelia miyamotoi—a bacteria related to the agent of Lyme disease. (More info: Lyme Disease by the Numbers.)

Naturally, different kinds of ticks transmit different disease-causing pathogens — and the list of tick-borne pathogens continues to grow. Plus ticks can transmit more than one pathogen at a time. Example? The blacklegged tick  (aka the deer tick) can transmit Lyme disease, anaplasmosis and babesiosis all at once. Here’s the short list:

  • Blacklegged tick: Lyme disease, anaplasmosis, babesiosis, Powassan virus
  • Lone star tick: ehrlichiosis, southern tick associated rash illness (STARI), tularemia
  • American dog tick: Rocky Mountain spotted fever, tularemia

Does every tick convey disease-causing pathogens?

No. Ticks don’t share a common destiny. Not every tick carries the pathogens that make us sick. Here in the Northeast, three ticks transmit pathogens—the blacklegged, lone star and American dog ticks.

Larval ticks, the stage that hatches from eggs with only six legs (nymphs and adults have eight legs), aren’t thought to play a major role in disease. But if larval ticks take their first blood meal from an infected animal, well—they’re infected too. Once they morph into nymphs, they can transmit whatever pathogens they took on.

Note: it’s possible that Powassan virus, carried by the blacklegged tick, can be transmitted from a female to her offspring — and that larval blacklegged ticks can transmit Borrelia miyamotoi, a type of relapsing disease. And what’s a relapsing disease? It’s when signs and symptoms of disease return after it seemed the disease was gone.

Blacklegged nymphs cause the most disease—partly because

  • they’re roughly the size of a poppy seed—not easy to see, and …
  • they’re active in spring when people aren’t thinking about ticks — though it’ll be summer before symptoms show.

Some nymphs and adults never acquire pathogens. Not every tick is infected. The rate of infection differs throughout the region. No common destiny there.

If I find a tick crawling on me, am I at risk for disease? And … how do they transmit disease?

Ticks transmit pathogens only while they’re attached and feeding. So no, a tick can’t infect you while it’s still looking for a place to feed. Once it’s fed, it’ll drop right off. That said:

  • if you find a tick crawling on you, don’t squish it
  • brushing ticks off your clothing is no guarantee they’ll stay off.

But if you keep a small vial of rubbing alcohol in your backpack or bag, you can quickly kill ticks by dropping them in. And that’s one less tick in your neck of the woods.

How do they make you sick? Ticks pick up pathogens from one organism (make that the mouse rummaging around under the shrubbery) and transmit them to another (make this one your kid). Here, not for the faint of heart, is how it works:

Larval ticks slide their mouthparts into the mouse — their soon-to-be host — and begin sucking blood. (Those mouthparts might seem a poor excuse for a head, but they get the job done.) At the same time, their saliva enters that mouse’s bloodstream — and yes, the saliva might be carrying pathogens. The time required for pathogens to pass from tick to host is variable. While viruses such as Powassan virus can be transferred within minutes, bacteria appear to take longer. (Just how long is open to debate, so we won’t get involved in that one.)

Need to remove a tick? Learn how here: Its tick season. Put away the matches.

We’ve got a couple of other posts in the pipeline, so we won’t return to this riveting topic until early or mid-July. But do stay tuned.

Comments Off on Tick and Mosquito Repellent Safety—for You and Yours

Tick and Mosquito Repellent Safety—for You and Yours

You might have noticed that we’re having a bit of a crisis with ticks and mosquitoes. They bite, they suck, and they can transmit pathogens to us during their feeding. One of the many things that we can do to avoid ticks and mosquitoes is to use repellents. But there are two important ideas to consider before picking a product from the shelf:

  1. Not every product has been proven effective, and
  2. The safety of a product depends on how you use it.

Product Efficacy
More than ever, an old adage reigns true: buyer beware! When it comes to tick and mosquito repellents, there are a number of products that claim to be effective—but offer no evidence or data to support the claim. This is especially true of many “natural” products with essential-oil active ingredients. Why? Products with essential-oil active ingredients don’t have to pass a scientific review by the U.S. Environmental Protection Agency (EPA) and can go to market without demonstrating that they work. These products give users a false sense of security that they are protected against biting insects when they are not. Learn more about this topic from our Tick FAQ section, What natural products can I use to repel ticks? For details on what products work, see the Insect Repellent Buying Guide from Consumer Reports

A confusing mix: some of these products can be applied to skin, others should not under any circumstance contact skin while wet. Read the label before using any pesticide product.

Product Safety and Use Restrictions: The Label Is the Law
As a pest management educator, I’ve said a million times, “the label is the law.” This is literally true—all labels of EPA registered products read, “It is a violation of Federal law to use this product in a manner inconsistent with its labeling.”

Here is a critical distinction about the products you might see on a shelf:

  • Products with the active ingredient permethrin can actually kill ticks and mosquitoes. According to one label, “This product must not be applied to clothing while it is being worn. Under no circumstances should bare skin or clothing on the body be treated. In other words, if you’re going to use permethrin, you have to treat your clothing or gear before you intend to use it so the pesticide can dry. According to the label on one product, this may be two to four hours.
  • On the other hand, products with active ingredients DEET, picaridin, and IR3535 can be sprayed on clothing and skin to repel biting pests. These products work by masking the cues that make you smell tasty to mosquitoes and ticks. According to one label for these products, Use just enough repellent to cover exposed skin… Do not use under clothing… Frequent reapplication and saturation is unnecessary for effectiveness.” 

We want you to enjoy the outdoors—and we want you to do it safely. Both types of products can be used to protect you, your friends, and families from the bite of blood-feeding organisms. To further protect health, always read and follow label instructions.

Minimize tick risk while minimizing pesticide risk

“I already found a tick on me!” – many people across NY

Many New Yorkers still equate tick activity with summertime, but blacklegged ticks, the ones that carry Lyme disease, anaplasmosis, babesiosis, Powassan virus, and Borrelia miamyoti, are most active in the spring and fall. (They can actually be active year round if the temperature and humidity levels are just right. Thus the heavy activity on the warm days in February.)

The goal is to prevent ticks from becoming embedded in the first place. But if you do find an embedded tick, remove it properly!

And in the springtime the blacklegged tick nymph turns to thoughts of questing. And nymphs are small. Poppy seed-sized small. If you are not intentionally conducting a daily tick check, you could easily miss one. And even if you are intentionally looking, one can occasionally get through your visual defenses. Which is why I was able to take this tick removal video after finding this tiny nymph on my leg when using my fingertips to search by feel. Since Powassan virus can be transmitted after 15 minutes of the tick being embedded, the incentive for not being bitten has risen dramatically.

Which brings us to the use of clothing treatments to protect ourselves. Permethrin is a pesticide that can be applied to clothing, footwear and gear before exposure. Researchers for the Center for Disease Control recently conducted a study showing how permethrin interferes with blacklegged, American dog, and lone star ticks’ ability to move and, thus, to bite. Read about it here.

Now the easiest option is to buy pretreated clothing or have your clothes professionally treated. The TickEncounter Resource Center has an excellent section of their website about tick repellent clothes, including where to get them.

For DIYers, permethrin can be purchased at many sporting goods and big box stores as a liquid or aerosol spray. But it must be applied safely and correctly. I try not to react in horror as people tell me they will spray the clothes they are wearing just prior to walking out the door. This product must NOT be applied to clothing while it is being worn. Or when one’s husband announces that he left his newly treated clothing in the basement. (And, yes, he sprayed the clothes down there too.) Permethrin must be applied outdoors. Don’t take my word for it. This information, and more, is found on the label. Let’s take a close look at the label from a commonly found product. (Does not imply endorsement.)

The label is the law and will tell you everything you need to know about using a pesticide correctly and legally.

The label, which is vetted through the EPA and, in NY, the DEC, provides information on the following topics (with a few examples thrown in):

  • Signal Word – this is your clue to how dangerous the pesticide is. To put it simply, categories include Caution (slightly toxic), Warning (moderately toxic), and Danger (highly toxic). This formulation of permethrin is labeled Caution.
  • DIRECTIONS FOR USE – includes, but is not limited to:
    • SHAKE WELL BEFORE USING. (Emphasis theirs. It must be important!)
    • This product must not be applied to clothing while it is being worn. Under no circumstances should bare skin or clothing on the body be treated. (Emphasis also theirs.)
    • Make all applications outside.
  • STORAGE & DISPOSAL
    • Store in a cool, dry place inaccessible to children.
    • Never place unused product down any indoor or outdoor drain
  • PRECAUTIONARY STATEMENTS – includes “Do not use on humans.”
  • FIRST AID – in case you didn’t follow the precautionary statements.
  • ENVIRONMENTAL HAZARDS
    • This product is extremely toxic to fish and other aquatic organisms.

We hit just some of the highlights, but it is all important. The label not only provides suggestions for using the product safely – the label is the law. That too is on the label: “Buyer assumes all risks of use, storage or handling of this product not in strict accordance with directions given herewith.”

So what is one to do? Why, follow the label of course. Decide which clothes you might wear into tick infested places and “select an outdoor area protected from the wind, spray outer surfaces of clothing (while not being worn) with a slow sweeping motion to lightly moisten the surface of the fabric, holding pump at a distance of 6 to 8 inches. Treat outer surfaces of each outfit, front and back, for 30 seconds on each side and allow to dry for at least 2 hours (4 hours under humid conditions). Pay particular attention to socks, trouser cuffs, and shirt cuffs.”

Then plan for the next application. “Clothing should be retreated after six weeks or after the sixth laundering to maintain adequate protection” I both mark the day I sprayed in my calendar and schedule an appointment for six weeks later.

By the way, professionally treated clothing also has a label, often found on the hang tag when purchased. Be sure to follow those instructions carefully as well.

Comments Off on The New Tick in Town (Part ll.)

The New Tick in Town (Part ll.)

Now for the science-y part of this post. (I suggest you re-read Part l. Can’t hurt. Might help.)

If you’ve read our other posts on the blacklegged tick (aka the deer tick), you might guess—and rightly so—that it’s the tick that’s been on our radar the longest; the one we (still) give most of our time and attention to. And all for good reason.

Sheer numbers (how much Lyme disease we’ve seen; what the co-infections are and how commonplace they are; its reputation as the “great imitator”) keep the blacklegged tick in the spotlight. Meanwhile, with the exception of Long Island, the lone star tick is rarely seen in the metro New York area and points north. But it has colonized some islands off Connecticut and established a toehold on Cape Cod in Massachusetts.

The lone star tick is on a roll, with its own suite of diseases and syndromes, some still mysterious. (Credit CDC)

Indeed, the lone star tick’s potential for harm could, somewhere down the pike, become a force all northerners face.

And consider this: though deer serve as a great food source and taxi service for ticks, they are immune to Lyme disease. Not so with the lone star tick. Because given the right circumstances, it can kill even deer.

So … what diseases or conditions does this tick carry—and could any be fatal to people? Here’s the short list:

  • Ehrlichiosis is nasty. Upward of two percent of those who get it might die.
  • Tularemia is nasty too, though less so than ehrlichiosis.
  • Heartland virus is rare—and most people who do get it have mild symptoms; perhaps none at all. But yes, some will die.
  • Alpha-gal syndrome? Perhaps—especially if you don’t know it for what it is. While the symptoms can be frighteningly intense, not everyone reacts with that same level of intensity. Plus this syndrome’s transcontinental spread in places lacking lone star ticks leads to yet-unanswered questions.

Ouch! Lone star ticks attach quickly—and some people react quickly. Sometimes it looks like this. (Credit: Copyright © 2015 American Medical Association)

So how about STARI, or southern tick-associated rash illness—can it do you in? My careful search turned up zilch, zip, zero. Doesn’t mean STARI won’t send you to an early grave. But if it could, I can’t find credentialed scientific sources to back up such a claim. You’ll be interested to know, though, that the rash STARI stands for can, on the surface of things, make you think you might have Lyme disease. And more unanswered questions: as of August 2017, the pathogen that causes STARI remains unknown.

Pests and pupils don’t mix

Year in and out, outreach to schools has our community IPM staff going back to school. Literally. We work with maintenance staff, nurses, groundskeepers, teachers, and parents. We provide the insight and know-how it takes to keep kids safe from pests and pesticides both. But schools are tricky to manage because—well, think of them as a village. You’ve got your cafeterias, laboratories, auditoriums, theaters, classrooms, athletic fields, playgrounds. Add in vacation and after-hours use for public meetings, community sports teams, summer schools and camps. Plus, New York’s laws restrict when, where and how pesticides can be used at school.

Which means you’ve got work. Because chances are, you’ve got pests.

Worried about ticks? By rights you should be. The hazards can hardly be overstated. We help teachers, school nurses, and entire communities learn how to stay tick-free regardless the season—and warn them that old-time remedies could increase the likelihood of disease.

Next up—unsafe playing fields. Is there goose poo on athletic fields and playgrounds? It’s not just unsanitary—it makes for slick footing and falls. And take it from us: weedy, compacted soil is a “slick footing and falls” risk too. How to manage turf, pesticide-free? We teach repetitive overseeding as a thoughtful alternative to repetitive herbicides. We’ll get to that in another post.

And then you’ve got your ants, bed bugs, cockroaches, drain flies, drugstore beetles, fleas, grubs, lice, mice, mosquitoes, pigeons, rats, termites and wasps. Did we say we get calls? Each year we field several hundred. Then, of course, there’s the workshops we lead, the conferences we speak at, the media interviews we give. Work, yes, but also deeply rewarding.

We give awards: IPM, excellence, and Julie Suarez

True — this media release dates back to January 4. But that’s not so long ago, and for someone like Julie Suarez it bears repeating. In short: we presented Julie (whom you’ll meet in a minute) with an Excellence in IPM award for—well, we could name a host of reasons. But we’ll let this speak to some of the best.

Advocacy and accolades earn Excellence in IPM award for Cornell champion Julie Suarez

ag industry — not to
mention flowers in our landscapes. Courtesy Dawn Dailey O’Brien.

GENEVA, NY, January 4, 2018: Julie Suarez’s passion is people. People at work, people at home, people in need. Whether it’s about the farm or urban communities, she’s keenly aware of the pests and the problems. She knows the issues, the legislators, the associations and nonprofits. She’s a natural.

Now Suarez, assistant dean of Governmental and Community Relations at Cornell University’s College of Agriculture and Life Sciences (CALS), has received an Excellence in IPM award from the New York State Integrated Pest Management Program (NYSIPM) for her unstinting advocacy for the people and programs at Cornell on issues that matter to all New Yorkers.

An accomplished facilitator, Suarez helps people

  • deal with invasive pests that threaten the livelihood of many farmers
  • preserve the pollinators—the honey bees and their kin—that are key to growing fruits and vegetables worth $1.15 billion to New York’s economy
  • cope with the relentless pressure of ticks and tick-borne diseases, which affected an estimated 8,000 New Yorkers in 2017 alone

Accolades for Suarez include:

  • Julie was instrumental in addressing the crisis when a new pest, a tiny fruit fly the size of a pinhead, threatened to put berry farmers out of business. She would answer questions, provide guidance and inform—usually responding to emails within minutes. I don’t know how she did it.
  • Julie reached out to me about research on pollinator health as soon as I arrived at Cornell. I’m impressed with the breadth and depth of her knowledge and her ability to work with scientists, officials and stakeholder groups statewide.
  • Julie is keenly aware of the key issues for state legislators, noting the committees they serve on and the needs of their constituents. That’s how the NYSIPM Program became involved with the Senate Task Force on Lyme and Tick-Borne Disease.

“Julie is proactive, strengthening the bonds between  the  IPM  Program  and the community at large,” says New York Senator Sue Serino, herself a leader in the fight against Lyme disease. “She consistently exceeds the expectations of those around her.”

“Julie brings legislators in Albany to Cornell and Cornell researchers to the legislators. She gets it that programs like ours take science to the people,” says Jennifer Grant, director of NYSIPM. “It’s a privilege working with Julie to serve all New York’s citizens.”

Suarez received her Excellence in IPM award on January 4 at the NYS Agricultural Society’s Annual Forum in Syracuse, NY. Learn more about IPM at nysipm.cornell.edu.

Comments Off on Ticks and the freezing weather

Ticks and the freezing weather

“That is a bracing cold, an invigorating cold. Lord, is it cold!” – Sheldon Cooper

It is inevitable that when the temperatures drop below zero we are asked “Will this extended period of extremely low temps kill off ticks?”

First, the bad news. We do not expect the cold to directly affect blacklegged or dog ticks as they are adapted to this climate and will survive just fine under the blankets of leaf litter and snow.

The good news, followed by some bad news, is we are basically looking at a reversal of the large quantities of ticks in 2017 that began in 2015 when oaks in New York underwent a mast seeding event. (In simple terms, there was an enormous amount of acorns on the ground across the state. If you want to delve more deeply into the mast year phenomenon, check out Mechanisms of mast seeding: resources, weather, cues, and selection.) Abundant quantities of food led to a large quantity of small mammals in 2016. Large numbers of small mammals led to a substantial number of ticks in 2017. Researchers at the Cary Institute of Ecosystem Studies have decades of field research to back up the relationship, and lag time, between mast years and Lyme disease risk.

Which brings us to the current frigid weather, and probably even more importantly, the ice under the snow, and how it will impact small mammals. Animals that have a harder time finding food are more likely to (in order of lessening consequences) die of starvation, succumb to other stresses such as disease or predation, fail to mate, give birth to fewer young, and give birth less often. In a nutshell, there should be fewer hosts come spring. And fewer hosts eventually lead to fewer ticks. Good so far.

But there is some bad news, too. During the time of high tick numbers and fewer small mammal hosts, each of us, and our companion animals, are at greater risk of coming into contact with questing ticks. So as soon as the temperatures rise into the mid-30s (and we know you will be out enjoying the veritable heat wave), ticks will be questing and we need to Steer Clear of Ticks and the Diseases They Carry — the IPM Way.

I am afraid the search for a reason to fully embrace the cold continues.

It’s (still) tick season — and will be evermore

Sorry to bring up a sore subject, but it’s still tick season. And will be all year round. What … during winter? Really? Yes. But for starters here’s your pop quiz:

A tick’s lifespan is

  • three months
  • ten months
  • twenty-four months (that is, about two years)

The best way to remove a tick is to

  • swab it with nail polish
  • hold a hot match to its behind
  • pull it straight up with fine-point tweezers

Even 15 million years ago, it was tick season. Trapped in amber, this tick carries Lyme-causing bacteria. (Photo credit Oregon State University.)

But back to our intro. Here’s the scoop: an adult female that hasn’t yet managed to grab hold of a large animal (think deer — or person) to get that all-important blood meal (can’t lay eggs without it) doesn’t want to wait around till a sunshiny summer day next year, because by then its number is up. Besides, the mice, chipmunks or birds it fed on earlier in its life cycle have only so much blood to go around. So that tick stays just below the soil where tall meadow flowers or low shrubs grow. Waiting. Waiting for a thaw barely long enough for it to scramble up one of those stems.

Waiting for the cues that tell it a warm-blooded animal is at close range. An animal that might be you.

And now for a look at our quiz. A tick’s lifespan? Your answer is (drumroll) C: upward of two years. Here’s how it works: Ticks spend a lot of time in dormancy, aka diapause. Eggs are laid in spring, tucked away out of sight. If some critter doesn’t find and eat them, they’ll hatch during summer as larval ticks (seed ticks, they’re sometimes called). Larval ticks are not infected with Lyme when they hatch — indeed, they’re pure as the fallen snow.

Meanwhile if likely hosts — those mice, chipmunks or birds — wander by, the ticks latch on. And if a host is already infected with Lyme disease or any of its nasty co-infections, those larval ticks, pure no more, are infected too.

Larvae that make it this far morph into nymphs, and it’s diapause season again as the nymphs wait it out till the following spring. Assuming these ticks are now carriers —and about 25% will be — spring is the worst time of year for us. Because these ticks are tiny enough (the infamous poppy-seed stage) that they’re easy to overlook. If you get bit, ipso facto — you get Lyme (and quite possibly a co-infection too).

Things slack off in late summer as surviving nymphs enter a diapause that lasts till the following spring. But you can’t let down your guard, since by mid-fall through winter you’ve got those adult ticks to consider. The good thing (if “good thing” there is)? While half of these sesame seed-sized ticks are infected, they’re also easier to spot and remove.

Our second  quiz item? If any of these strike you as valuable folk wisdom, strike the valuable part and know it ain’t so. Nail polish? Matches? Don’t even think of it. Those first two items are just likely to tick that tick off — and it’ll vomit its gut contents into you in its hurry to get out. That is, if it can get out quickly; if it’s really drilled in, it has downloaded a cement-like substance to anchor itself. It takes some doing to disengage, however persuasive the nail polish, burnt match, or myriad other folklore remedies. (Twisting it is another no-no that comes to mind, mainly because someone asked me about it mid-way through this post.)

Pointy tweezers, held right against your skin and gripping the mouthparts, are the way to go. (Image credit tickencounter.org)

If you value your health, get yourself some pointy tweezers, sold for needlepoint and other crafts, and carry them with you always in your bag, backpack, or whatever you haul around. Grasp that tick as close as you can get to your skin and pull steadily. Did its mouthparts remain glued within? Not to worry — the tick will feed no more. And before too many days go by, your exfoliating skin (that’s when the top layer of skin cells drift away) will exfoliate them in turn.

With ticks, prevention can include everything from doing routine tick checks to wearing repellent clothing when you’re outdoors — regardless the season. And you can’t do much better than this for advice about dressing right.

Meanwhile here’s your catchphrase: 32, ticks on you. “32” as in 32°F. Stay watchful — and stay safe.
