IPM Celebrates the New Year With News for You

We decided on a new look for our IPM Year in Review—our first-ever calendar. Who doesn’t put calendars to good use? I’ve already noted a couple of dentist appointments in mine.

And for you, dear reader, we offer our calendar sampler—four months, four topics, four new things to learn.

February:

It’s February and shivery cold—and time to pay careful attention to the nooks and crannies so inviting to the critters that call your home theirs. Do you hear varmints scurrying in the basement, the walls, the ceiling? Mice and kin (OK, rats) have taken up lodgings and are way overdue on the rent.

Block their access. Start with a look in the basement. For mice, the entryway need be no larger than a dime; for rats, a quarter. Take it from us: if their heads can fit through, their fat little tummies can squeeze through too. Found a hole? Found several? Get some sealant and fill ’em up.    https://conservesenecacounty.com/wp-content/uploads/2015/04/mouse.jpg

March:

Ah, March—when winter marches into spring. School kids are antsy to get outside. And us? We’ve got ticks on our mind. Here’s your blacklegged tick, up close and personal. Soon these ticks will be out and about; the health hazards can hardly be overstated.

So practice the drill—how to ID them, dress for the occasion, do tick checks. Planning a hike? Wear light-colored duds (the better to see you with, my dear), pull your socks over your cuffs—and as soon as you’re home, do tick checks. Got pets? Check them too.

Btw, though their common name is “deer tick,” many scientists prefer “blacklegged tick.” We’re speculating here—but could that be because otherwise people will get the mistaken notion they can catch Lyme from deer, which they cannot? Yes, deer are among the movers and shakers in the world of Lyme. But by the time they’ve donated their blood to the cause, mama tick will have dropped off and called it a day.

Regardless: these ticks have a lineage that goes way back. In fact, a fossilized tick was found in a chunk of amber where it dined on mammalian blood some 20 million years ago. It carried babesia—a disease that’s still in action today.

May:

It’s May now; summer is nearly here and the weeds are growing like—well, like weeds. Unperturbed by spray, horseweed and waterhemp are gaining ground, dramatically reducing crop yields. Regaining control over these herbicide-resistant weeds is a major issue for New York’s farmers.

Here’s one approach. With nearly 20 rubbery fingers on each hand and 20-plus hands, this cultivator earns its keep by dislodging, uprooting, and burying weeds while they’re still small. The boxy white contraption with two dark “eyes” and mounted at head height with a cable running toward the cab? That’s a camera, designed to move the cultivator left or right. It’s job? Keeping the cultivator aligned with the crop.

November:

Bed bugs are back, the scourge of small and big towns alike. No, they don’t spread disease. Yes, on some of us they leave itchy red welts—while others have no symptoms at all. But you don’t need to throw all your belongings away, we promise. IPM now offers to ultimate in How To guides: How to Get Bed Bugs Out of Your Belongings.

Your hair dryer and vacuum cleaner will be your steadfast companions in your battle to regain control over your mattresses, shoes, clothes, and electronics. The hair dryer’s gentle heat will flush the little buggers out of hiding; the vacuum cleaner sucks them up. The guide also provides instructions on how to quarantine your belongings long enough to starve them into oblivion. Bed bugs, even during the holidays, are manageable.

Let IPM help you!

2018’s Best of NYS IPM

“None of us is as smart as all of us.” –Ken Blanchard

2018 has been quite the year and we have been busy blogging, tweeting, videoing, and Facebooking about it. Here’s a recap of some of our more popular 2018 offerings:

ThinkIPM – our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.

Our most popular blog post was actually a guest blog by Paul Hetzler, CCE St. Lawrence County, Move Over, Medusa: Pretty? Poisonous! in the Caterpillar Clan. We’re big fans of his writing and this post on a venomous caterpillar caught a lot of your attention as well. (photo credit: Wikimedia Commons)

 

Are you safe now?

Ticks in February?

Ticks in the cold was also a popular topic. And relevant to now! Check out these two blog posts, Ticks don’t care what month it is and Ticks and the freezing weather. Hopefully they both convince you to keep up your daily tick checks.

While visiting our blog, you have also been checking out older posts. Our second most popular post viewed in 2018 was a 2014 post, Identifying Your Pest – with Poop?. There are a lot of budding scatologists out there.

Other IPM Blogs – Besides ThinkIPM, we have more dedicated blogs, and you don’t need to be a specialist to subscribe to them. Here are some of the more popular posts:

The Spotted Wing Drosophila blog has an obvious focus, but the post Spotted lanternfly found in two counties in NY captured the most views.

 

Biocontrol Bytes was begun at the end of 2018 and many of you have been enjoying the updates on the Creating habitat for beneficial insects project.

 

We saw a number of news reports about bed bugs in schools, so we wrote Bed bugs in schools aren’t going away in The ABCs of School and Childcare Pest Management blog. And you read it. We just wish the news reporters and commenters did too.

 

The 2017 NEWA Survey: IPM impact includes such gems as “93% agreed or strongly agreed that NEWA pest forecast information enhances IPM decision-making for their crops”.

 

Gypsy moths on Christmas trees? Check out the Tree Integrated Pest Management blog and see how it’s now a thing in the Gypsy Moth Caterpillars -Scout for them now post.

 

Facebook

When it comes to Facebook, video rules. Our most popular Facebook post was our claymation video, Life Cycle of the Blacklegged Tick (and Lyme Disease Prevention!). And, by the way, this claymation was part of a large Don’t Get Ticked NY campaign launched in 2018!

Our new Spotted Lanternfly video, Have YOU Spotted Lanternfly Egg Masses was just posted, but it has already reached the number two spot. This invasive insect is getting a lot of attention and we need your help to keep track of it in New York.

 

Twitter

We’re not surprised that our most popular Tweet of 2018 was about spotted lanternfly. Follow us on Twitter to keep up with the latest information.

 

 

 

Annual Report

This might be cheating, because it was just released and we have no data to show its popularity, but our 2017-2018 annual report is a 2019 calendar and everyone we have shown it to has been pretty excited.

Here’s a picture of the spotted lanternfly you have been hearing about.

 

 

 

 

 

 

 

So, as we raise our glasses to 2018 and look forward to 2019, include keeping up with NYS IPM Program amongst your resolutions.

Happy New Year!

Comments Off on Tick IPM – The Dog Zone

Tick IPM – The Dog Zone

December’s wintery breath is already clouding the pond, frosting the pane, obscuring summer’s memory… ― John Geddes

Winter had an early showing in New York this year. So when the temperature hit 50oF yesterday, I took the opportunity to spend some time outside. And, as I had warned people that follow me and NYS IPM on social media with this great graphic by Matt Frye earlier today, the ticks were out and about. (Side note: follow us at www.facebook.com/NYSIPM and twitter.com/NYSIPM for up-to-date information you can use.)

Now, the ticks weren’t as active as the 70 oF day last February. I had to put in a little more effort to find them. But while tick dragging, I noticed where others regularly go off the beaten track (or, rather, create their own beaten track). We’re going to call this The Dog Zone.

There’s a perfectly good paved path, but the dog print laden path is inches from the woodline.

Let’s face it. Dogs want to stick their noses into interesting places, and there just aren’t that many interesting places on the pavement. So they will take advantage of the length of the leash to get off the pavement and follow the scent trails. And the smells of mice, chipmunks, squirrels, raccoons, deer, rabbits (you get the idea), are more likely to be wafting at the edge of the woods than in the short grass. I watched dog walkers leave the pavement themselves to indulge their furry friends. Unfortunately, ticks are more likely to be in those areas.

Talk to your vet about options to protect your pets from ticks and tick-borne diseases.

Typically the dogs are between their walkers and prime tick habitat, but leaving the pavement still puts you more at risk if you are not taking preventative measures. And let’s not forget to protect your dogs too. There are multiple products out there including different topical and oral products as well as collars. These are described in our Tick FAQ under What should I do to protect my pet from ticks?. (Funny story, numerous people have asked me if they could put tick collars around their ankles. Just… no. You can, however, apply permethrin to your own clothing.)

But the really important message here is that ticks are active during the winter. And even if the air temperature is less than 37oF, a protected, sun-exposed area next to a woodline can be significantly warmer. Last week a site we were monitoring had an air temperature of 40oF, but the ground temperature was 50.6oF. So I will end by emphasizing the need to protect yourself from ticks year-round and conduct a tick check EVERY DAY.

Comments Off on Tick Check 1.2.3.

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

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.

The low-down on ticks. Part 1A, Biology Q&A

Ticked off about ticks? You are not alone. And knowing the what, where, why, etc. is critical to knowing how to deal with them. So here it is, the first in a series: the low-down on that pest we love to hate.

May you, dear reader, stay tick-free and healthy.

1. What, exactly, is a tick?

Ticks are related to mites and spiders—but not to insects. (Now don’t go worrying about spiders—in the Northeast, virtually all are common victims of common misunderstandings.) Ticks have four life stages: egg, larvae, nymph and adult. All stages (well, not the eggs) feed on blood for energy to grow and later to reproduce. Larval ticks have six legs; nymphs and adults have eight.

Those things that look like antenna? Not—they’re highly adapted legs that process vital information. And that snout in the middle? Blood-sucking mouthparts. (Photo CDC)

Right now, three species are a health concern here in New York: the blacklegged tick, the lone star tick, and the American dog tick.

2. What do ticks look like?

Regardless the species, unfed ticks look like flattened teardrops with eight legs. And depending on their species, life stage and sex (male versus female), they have different color patterns on their bodies. But after they’ve eaten, their abdomens (the females’ especially) can expand so much that it’s really hard to know which is which. You can get positive IDs here.

Just keep in mind that learning a tick’s identity doesn’t mean you know if it’s carrying a disease.

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

As for size? Again, that depends on the species, its life stage, and whether it has fed (and for how long). For blacklegged and lone star ticks, larvae are the size of the period at the end of this sentence. Nymphs? Think poppy seeds. Adults? Sesame seeds. When fully fed, adult females can be as large as a raisin.

American dog ticks, though, are a tad larger than the other two.

3. Are ticks a new problem? Why have we been hearing so much more about them lately?

Turns out ticks are nothing new. In fact, evidence suggests that ticks were carrying Lyme disease pathogens 15 to 20 million years ago (Lyme Disease’s Possible Bacterial Predecessor Found in Ancient Tick). What is new? We’re seeing far more ticks throughout the Northeast and much of North America than during any time in recorded history. And of course the more ticks in the neighborhood, the greater our risk of disease.

Why are ticks on the move? For one, (sub)urban sprawl leaves small patches of wooded areas—great habitat for mice and deer but far less welcoming to their traditional enemies—hawks or foxes, cougars or wolves. (More later on the role of mice and deer in tick-borne diseases.) In addition, a warming climate makes northern areas more hospitable for ticks.

Ah, yes. A place to call home—and nary a wolf in sight. (Photo provided.)

4. Where do ticks live? How do they find me? And where did the deer ticks go?

Blacklegged ticks are usually found in woodlots, forest edges, and groundcovers such as pachysandra or periwinkle—places where leaf litter, shrubs, and tree cover provide the moist environment they need. And how do they find us? Just as we sometimes go on quests, so too do they. Only they’re not seeking adventure or the Holy Grail, but simply a host. A host that provides the food (think blood) they need to thrive, or at least survive.

About deer ticks? Years ago, researchers thought they’d found a new species and gave it the common name “deer tick.” Turned out it was the same old blacklegged tick that’s been here since time immemorial.

No matter that these ticks lack eyes—questing ticks stand on the edge of a twig or leaf, their first pair of legs extended. Evolution endowed them with cleverly designed legs: they’ve got sensors to detect temperature, the carbon dioxide those hosts exhale, and odors or sounds specific to those hosts. When a host brushes past, they grab on tight.

The nymphs typically quest below a person’s knee-height. Because adult ticks feed on larger animals, they might quest higher up to find a host—as high as your waist-height or mine.

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

The lone star tick thrives in a wide range of habitats, from shady forests to sunny lawns or roadsides. Unlike the blacklegged tick, the lone star tick hustles toward its prey, even across pavement or dry sand. Other distinguishing features? Well … it’s lots more aggressive. Imagine a tick that travels three times as fast as the blacklegged tick, has excellent vision, and hatches in stinging swarms that can put fire ants to shame.

Last but not least—the American dog tick. Forget the woods: this tick thrives in warm, dry places—roadsides, grassy fields, scrubland and lawns. Larvae and nymphs mostly feed on small mammals, while adults climb grass, brush, or twigs to find medium-sized animals—people included. And sometimes American dog ticks could be even more aggressive. TickEncounter has reported seeing American dog ticks follow a regular source of carbon dioxide that attracted them for upward a few hundred yards to the house. And in one memorable case ticks were crawling up the outside walls toward window screens and doors. Now if that doesn’t give you the willies….

No matter which tick you might collide with—this is one party you don’t want to host.

Stay tuned for another informative post on the biology behind that pest we love to hate.

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.

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.
