Help! I found a tick on me! – Spring Edition

It’s spring fever. That is what the name of it is. And when you’ve got it, you want — oh, you don’t quite know what it is you do want, but it just fairly makes your heart ache, you want it so! ~Mark Twain

Part of what we want is to be outside! And, with COVID-19, more people than ever are heading to the great outdoors. Which, unfortunately, is where the ticks are. And ticks want a blood meal. In the early spring we still have some adult blacklegged tick adults hanging around. But the time has also come again for blacklegged tick nymphs to look for a meal. As well as American dog ticks. And lone star ticks. And the recently discovered Asian longhorned tick.

When taking pictures of ticks for identification purposes, try to have the tick fill as much as the frame as possible and take multiple pictures to increase the chances of one being in focus.

And people want answers to questions such as this one, “I just removed a tick from my child. What should I do now?”

We’ll start by stressing there are steps you can take to reduce the likelihood of a tick bite. This has been covered in multiple places including our Don’t Get Ticked NY website and various blogs including keeping dogs tick free, using repellents effectively, and the proper use of permethrin treated clothing. If you do find one attached, we covered tick removal in the blog post It’s tick season. Put away the matches and YouTube video How to remove a tick.

Identifying ticks

With four major tick species in New York, it’s important to identify which one bit you. Each species, life stage, and, for adults, whether it is a male versus female have different color patterns. The length of the mouthparts vary between ticks. They have festively named festoons which can also help with ID. As ticks are freakishly small, and we are looking at even smaller parts of their body, it is handy to have a magnifying lens, a good smartphone camera and a steady hand, or, better yet, a microscope. Don’t have one? There are options for having someone identify the tick for you. They include:

If you want to give identification a go, the TickEncounter Resource Center has an excellent guide highlighting the scutum, festoons, and life history. Life history? Yes! Life history should only be used as a clue, however. Ticks don’t read the books and every life stage of the blacklegged tick has been found throughout the year.

Tick-borne pathogens

Identification matters because different tick species can transmit different tick-borne pathogens. Which is information you want to give your health care provider to help them make an informed decision..

First, let’s be clear that we provide mostly information about ticks. Any information about tick-borne pathogens that cause disease is restricted to what pathogens are carried by what tick species and how they are transmitted. It is beyond the scope of our roles as IPM Educators to discuss diagnosis, symptoms, and treatment. (For this information, we refer you to the Center for Disease Control and Prevention’s Tickborne Diseases of the United States page.)

The chart show that blacklegged ticks can transmit the pathogens that cause Lyme, Anaplasmosis, Babesiosis, Powassan Virus, Borrelia miyamotoi, and Erlichiosis. Lone star ticks can transmit the pathogens that cause Erlichiosis, STARI, possibly alpha-gal allergy, Canine Erlichiosis, Tularemia, and possible Rocky Mountain Spotted Fever, and American dog ticks can transmit the pathogens that cause Tularemia, Rocky Mountain Spotted Fever, and cause tick paralysis.

Different tick species host different pathogens. Importantly, ticks can transmit more than one pathogen at a time.

The poster to the right shows what disease pathogens can be transmitted by the three ticks of greatest human concern in NY, the blacklegged tick, dog tick, and lone star tick. To date, no Asian longhorned ticks in the U.S. have tested positive for any tick-borne pathogens.

What’s the risk?

A question you will likely be asked when reporting a tick is, “How long was the tick attached?”. In my honest opinion, this is a rather silly question. Ticks are very, very good at not being noticed. They want to stick around for up to a week feeding. To help deter detection, they release antihistamines and painkillers in their saliva. And, perhaps more importantly, none of us want to admit to ourselves that a tick was feeding on our blood for days. It’s a hard psychological pill to swallow. There is also some question in the medical literature about the time required for transmission of the bacteria that causes Lyme disease. Especially if the tick was removed improperly. And we know Powassan virus can be transmitted in a matter of minutes. But the question will still likely be asked.

The answer? Take another look at that tick and refer to TickEncounter who has helpfully created charts showing the growth of ticks as they feed.

I have found this chart particularly useful when people swear the tick was on them for only a few hours. Having an estimate of the attached time is helpful information for your physician.

A microscope is definitely handy to help see the distinguishing features on removed ticks.

And now back to the original request: “I just removed a tick from my child. What should I do now?” In this case, we were able to put the tick under a microscope to help with identification. Before reading on, what would you say it is?

 

This looks like a blacklegged tick nymph which was attached for 1 to 2 days, so any pathogens carried by the tick might have been transmitted. I recommended printing the Tick-Borne Diseases and Non-Pathogenic Impacts sheet, circling the identified species and life stage, writing down the estimated time of attachment, and calling their health care professional.

One last question often asked – “Should I get the tick tested?”

We follow the CDC recommendation of not having the tick tested for diagnostic purposes. The reasons include:

  • Positive results showing that the tick contains a disease-causing organism do not necessarily mean that you have been infected.
  • Negative results can lead to false assurance. You may have been unknowingly bitten by a different tick that was infected.
  • If you have been infected, you will probably develop symptoms before results of the tick test are available. If you do become ill, you should not wait for tick testing results before beginning appropriate treatment.

    Promoting IPM, including monitoring and personal protection, as best management practices for avoiding ticks and tick-borne disease.

And finally…

This really isn’t the best time to need to head to the doctors. If you don’t get bitten by a tick, you don’t need to go through this process. Our Don’t Get Ticked NY campaign provides you with the information you need to protect yourself from the risk of tick-borne diseases. Check it out before your next trip outdoors.

Let’s stay safe out there as we enjoy the beautiful spring.

Timely School IPM Tip #3: Sanitation

This is the third and final post dedicated to tactics of school IPM most appropriate to the current situation of shuttered schools. (If your building is open to provide meals for at-home students, we applaud your efforts!)

Post #1 Scouting, Post #2 Exclusion. Sanitation is a third step in structural pest management, as it reduces pest habitat (food, water, shelter).

Sure to gain your attention, this photo (below) proves there’s been a lack of sanitation (and scouting, and exclusion!) But this scenario might well be the case in buildings left unattended during the Covid-19 closures. This may seem extreme, but sanitation isn’t just removing dead rodents, it’s keeping storage areas, kitchens and classrooms free of crumbs, condensed water, and recyclables.

photo shows a sticky trap with three mise on it. one is still alive, the other two dead. one is just what's left after other pests have fed on it.

Below is a (partial) look at our recommended Best Management Practices chart. We left off the Daily practices in favor of what can be done best during shutdown. Sanitation is more than just cleaning greasy stove tops.  It’s getting to all those places we’d rather ignore, and reducing clutter and keeping food products in pest-proof containers.

a partial chart of things to do monthly, quarterly or annually to reduce pest problems in buildings.

For example, the non-chemical practices to reduce cockroaches:

The key factor is sanitation and reduction in habitat. Take care not to bring them in on packaging material (inspect incoming food). Clean up all spilled foods; don’t leave dirty dishes overnight; store all food in pest-resistant packaging; modify areas where pipes and utilities enter walls (caulk and screen all entrances); reduce moisture by improving plumbing and insulating pipes that routinely sweat. Empty garbage every day. Keep floor drains capped or full of water. Increase ventilation in moist areas. Baits are the most efficient and widely used form of control, but prevention is the least toxic method of control.

(Above) Mouse droppings are not just unsightly, they can cause allergic reactions and health issues, and can carry disease. Cockroaches exacerbate conditions like asthma. SANITATION also assists monitoring. If this area was cleaned last week, you can be sure the droppings are new.

Timely School IPM #1: Scouting for Building Pests

While pests like bedbugs are inactive waiting out school re-openings, the old standards like cockroaches and rodents can use quiet buildings to their advantage if habitat needs are met.  Food, water and shelter are available in areas such as storage rooms, kitchens, boiler rooms and crawlspaces. If your building is currently unoccupied, pest activity can go unnoticed by staff, especially if there is a disruption in pest control operator visits.

OUR NUMBER ONE SUGGESTION NOW IS…SCOUTING. Building maintenance remains (at this time) essential work. Just like in the summer months, buildings without students allow much great opportunity for extensive scouting and cleaning.

LOOK FOR PESTS, PEST ACTIVITY and PEST ENTRY POINTS. The partial inspection list below notes areas that may not be addressed daily during the school year.  Now is the time to move large pieces of kitchen equipment in buildings no longer providing meals.

Our New Look!

Back in 2013, the Northeast School IPM Working Group (NESIWG) received a Partnership Grant from the Northeastern IPM Center to develop a Best Management Practices (BMP) website.

logo of the northeastern I P M center

Reducing pest and pesticide exposure is important for children, just as it is for district staff and visitors. But schools are especially challenging to manage because they include such varied and heavily used settings such as classrooms, cafeterias, laboratories, auditoriums, theaters, playing fields, playgrounds and gardens.

With the help of many contributors, the NESIWG both created and collected resources for school IPM. We wanted to help administrators, school boards, parents, teaching and support staff, athletic directors, groundskeepers, kitchen staff and custodians how a designated pest management plan can reduce both pests and the need for pesticides. The website was a success.

By 2018, NESIWG members saw the need to update old links and fill out gaps in the content. Eager to keep the website a useful and comprehensive resource, the working group applied for and received a NEIPM Communications grant. Again using focus groups, the following changes were made:

  • a reorganization of the pest species list,
  • additional information on relevant pesticide use regulations in all Northeastern states,
  • grouping resources by stakeholder roles,
  • the addition of two new pages: Breakfast in the Classroom and Playgrounds

Additionally, the recent grant included an update of the working group’s homepage, a new ranking of regional school IPM priorities, a current membership list and an index of school IPM contacts in the Northeast.

Don’t Make Your Own Tick Tubes

“Frugality, I’ve learned, has its own cost, one that sometimes lasts forever.” – Nicholas Sparks

Commercially available “tick tubes” are tubes filled with permethrin-infused cotton. Mice take the cotton to line their nests and are treated for ticks every time they return home. It’s estimated that a typical ¼ acre yard needs six tubes twice a year, with a 12 pack costing ~$45 . Although this cost isn’t excessive, there are many videos and articles on making DIY tick tubes to help people save money. But what is the actual cost?

A dozen tubes covers about a 1/4 acre for $45. (Image does not imply endorsement.)

3 Reasons Why Making Your Own Tick Tubes is a Bad Idea:

1) They probably won’t work.

A pesticide product contains inert ingredients that help the active ingredient (in this case, permethrin) perform properly for the uses listed on the product label. The formulation used in commercially available tick tubes is uniquely suited for controlling ticks on mice. Other permethrin formulations are designed for other uses which are specifically listed on the label.

2) You could be putting yourself, others, pets, nontarget animals, and the environment at unacceptable risk.

Tick tubes target ticks attached to field mice. When spending time in the nest, mice expose themselves to the tick-killing products.

Tick tubes target ticks attached to field mice. When spending time in the nest, mice expose themselves to the tick-killing products.

The EPA will register the use of a pesticide only if rigorous safety testing shows it will “pose no unreasonable risks to people or the environment when used according to label directions.” Only those uses listed on a pesticide label have met this standard, and making your own tick tubes is NOT a use listed on the label of any permethrin product. One potential risk: Permethrin is highly toxic to bees. Bumble bees often nest in abandoned mouse burrows, so making your own tick tubes could harm these important wild pollinators.

3) It is against the law.

Because of Reason #2, the first sentence in the Directions for Use section of all permethrin products is “It is a violation of federal law to use this product in a manner inconsistent with its labeling.” Which, by the way, also means it is against your state’s laws.

Commercially available tick tubes cost more because it takes time and money to develop the right mix of ingredients and conduct the required safety testing to ensure that the product will control ticks without putting people, pollinators, and the environment at risk. DIY tick tubes that pose greater risks while providing poorer control of ticks are hardly a bargain; be sure to use the real thing.

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 Pests, Pesticides and Proposals: Funding IPM Community Projects

Pests, Pesticides and Proposals: Funding IPM Community Projects

Pests and pesticides—both can pose problems to our health, our environment, and our economy. At the New York State Integrated Pest Management Program (NYS IPM), we help New Yorkers address those problems safely and thoughtfully. How? Through innovative biological, cultural, technological, and educational practices. IPM, in a word.

Community IPM takes place in settings as varied as school buildings and grounds; residential and office buildings; gardens, parks and landscapes; and golf courses and right-of-ways. Now we invite grant proposals from qualified New Yorkers who want to develop, evaluate, or demonstrate feasible IPM methods. Budgets must not exceed $8,500. Our deadline: April 6, 2018. Funds must be spent by February 28, 2019.

The German cockroach needs no introduction. If it can get on your fork, it can get in your food. Credit Clemson University, USDA.

All projects must accomplish one or more of the following:

  • develop, advance, test or refine new IPM strategies;
  • demonstrate a link between IPM practices and reduced risk to human health or pesticide residues;
  • measure the positive change or potential impact of IPM practices or adoption, or survey current IPM knowledge;
  • develop Community IPM resources, such as brochures, websites, fact sheets, manuals, and apps for smartphones and tablets;
  • develop IPM educational programs, such as workshops or curriculum;
  • educate others about IPM through outreach and demonstrations.

Audiences could include school administrators, teachers and students; landscape and structural pest management professionals; vector control specialists; municipal employees; nuisance wildlife control operators; golf course personnel; arborists; right-of-way managers; day care operators—just about anyone, in fact. We encourage projects that reach new audiences or develop new partnerships.

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

Our Community IPM priorities include: develop or demonstrate solid strategies for dealing with rodents or cockroaches; develop, confirm or promote methods to lessen the impact of ticks; research, demonstrate or create outreach projects that promote pollinator health and conservation; and research and demonstrate alternatives to imidacloprid on lawns and athletic fields.

Yes, there are plenty more. But for 2018, these four are our greatest needs.

Got Questions? We encourage you to discuss your ideas with NYS IPM community staff, including:

  • coordinator: Jody Gangloff-Kaufmann, Long Island, 631-539-8680, jlg23@cornell.edu (Do you work outside Cornell University and Cornell Cooperative Extension? Get in touch with Jody Gangloff-Kaufmann.)
  • educator: Lynn Braband, Rochester, 585-753-2562, lab45@cornell.edu
  • educator: Amara Dunn, Geneva, 315-787-2206, arc55@cornell.edu
  • educator: Matthew Frye, Westchester, 914-285-4633, mjf267@cornell.edu
  • educator: Joellen Lampman, Albany, 518-441-1303, jkz6@cornell.edu

  • educator: Brian Eshenaur, Rochester, 585-753-2561, bce1@cornell.edu

And consider: the most common critiques of past proposals have been that the budget lacked in clarity, explanation or justification—and those seeking grants didn’t discuss projects ahead of time with IPM staff.

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.

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

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.
