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.)

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. Continue Reading →

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:

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

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

Comments Off on Getting ticked? Bummed about Lyme disease? You’re not alone

Getting ticked? Bummed about Lyme disease? You’re not alone

An NYS IPM Your NEWA Blog entry dropped into my inbox a couple of days ago — and since the entire conversation on my bus ride into work today was about ticks, a topic no one seemed to tire of, I just had to borrow from it for this post.

Here’s how it begins:

“Getting ticked? You’re not the only one.” That’s my colleague Dan Olmstead speaking. He continues:

“I was at Empire Farm Days working the New York State IPM Program booth last week. What do you think the most asked-about topic was?

“Every question I answered was about ticks. Ticks are most well-known as carriers of Lyme disease and they are on the rise. Changing weather and climate patterns could be partly to blame. Growing seasons are getting longer and ticks have more time to develop.”

Dan goes on to explain that range expansion is another likely factor coinciding with increasing numbers of mice and deer. These critters do well in fragmented habitat, whether it’s overgrown field, hedgerows — or expanding suburbs.

Mice infected with Lyme transmit it to the young ticks that feed on them. Meanwhile deer (birds too) pick up ticks in one place and ferry them to new, perhaps un-infested locations — making them complicit in transmitting Lyme disease despite the fact that, at least on deer, Lyme-free ticks (and yes, such ticks exist) won’t contract Lyme by feeding on deer.

But the black-legged tick (aka deer tick), host to Lyme disease and several other nasty co-infections, isn’t the only dog in the fight. It has friends — as it were. Here (courtesy the Centers for Disease Control) are the ticks we see and the most common diseases now associated with them:

Black-legged Ticks  Lyme, Anaplasmosis, Babesiosis and Powassan virus
Lone Star Ticks    Erlichiosis, STARI, and Tularemia
American Dog Ticks   Tularemia and Rocky Mountain Spotted Fever
Brown Dog Ticks Rocky Mountain Spotted Fever

When Empire Farm Days rolled around in early August, the tiny nymphs — the most dangerous stage for us humans — were still at it, still clambering onto the tall grasses and low brush or meadow plants that they’d perched on most every chance they got since May. They were waiting for the right host to come by. It’s called questing. And yes, these ticks are — metaphorically at least — on a quest that for them means life or death. (Most die but plenty remain.)

True, by now in late August, their populations have peaked. But even so they’re still eight-armed and dangerous.

Eight-armed? OK — make that eight-legged.

And typically by early August, it’s too hot and dry anyway for ticks to quest for hosts. But by early August this year, our colleague Joellen Lampman hadn’t seen the usual summer decline in black-legged tick questing. Ticks like to quest when humidity is greater than 85%, and 2017 assuredly hasn’t been stingy on that account.

Got ticks on your mind? Bummed because you’re stuck inside and feel like you can’t get out in the woods like you used to? Worried because deer have found your neighborhood, regardless how populated your neighborhood? Wondering how best to protect yourself?

Comments Off on Every Season Is Tick Season

Every Season Is Tick Season

At IPM we call it the black-legged tick because that’s its true name. Yet most people in North America — perhaps even you, dear reader — call it the deer tick. A name with curious stories to tell.

But first the commercial: every season is tick season. Impervious to all but the most bitter cold, ticks take shelter in the leaf litter in gardens and woods. Whenever it gets a little above freezing, they crawl out and up. Any adults that failed to find a host earlier in winter or fall scramble into knee-high vegetation. (Females need a blood meal before they can lay eggs.) There they wait patiently for some critter to brush against whatever stalk they’re clinging to, and when it does — they grab hold.

Even during this fickle February of 2016, when many places south of the Adirondacks have repeatedly lost their snow cover, leaving the barren ground to freeze hard, those ticks keep ticking along. Yes, many die. But many remain. On lovely sunshiny days when you wander outside to shake off a bout of cabin fever, be sure to dress right to keep ticks off you.

And having done that, relentlessly check yourself for ticks when you get inside.

Now back to our story. That name — deer tick — suggests that deer carry Lyme disease. If you’ve had a bout with Lyme or any of the less-than-pleasant co-infections that black-legged ticks also vector, just thinking of Bambi could give you the chills. But while deer assuredly spread ticks far and wide, they don’t vector Lyme. Which means a tick that is Lyme-free won’t pick up the Lyme pathogen from a deer.

The buck stops there.

Verdant summer meadows? Come winter, the ticks are still there.

Verdant summer meadows? Stay vigilant. It’s too easy to pick up tiny, hard to see nymphs  — ones already vectoring Lyme.

The critters that most commonly carry Lyme disease — notably mice, but also shrews and chipmunks — assuredly do get Lyme disease. But odd as it seems, it doesn’t knock them out. Instead they just keep chugging along, doing their mouse or shrew or chipmunk thing. Which includes transmitting the Lyme pathogen to ticks throughout their life cycle. Ticks that grow larger and larger. Ticks that eventually — instead of hanging out low to the ground where the mice are — become large enough to scramble into knee-high vegetation where they’re yet more likely to land on some hapless human. Or dog, raccoon, fox, coyote, skunk, cat, sheep, a ground-nesting bird, cow, horse … the list goes on.

Some, like deer and probably other wild animals, don’t get particularly ill — though it’s not been closely studied. But dogs, horses, and humans (less likely, cats) can get knocked for a loop. Even so, we likewise don’t transmit Lyme; the tick would already need to be infected. The buck stops there.

The next commercial: about that tick that snuck aboard during your post-lunch walk in the curiously warm February sun … you might not have as much time to deal with it as once was thought. Sure, in some cases it’ll be 24 to 48 hours before that tick starts transmitting Lyme. And not every tick carries Lyme or other diseases.

But still, better safe than sorry. Because recent research suggests: as you sit down to dinner that tick might already be dining too, but with consequences you don’t want to bear. Knowing that, relentlessly check yourself for ticks when you get inside. And even if you don’t care for school grounds or a summer camp, this IPM fact sheet is rich with useful information.

Dealing With Wildlife and the Laws That Protect Them

When we think about pests, bugs and mice are the first things that typically come to mind. But what if larger critters such as squirrels, bats, woodchucks, deer, or pigeons become troublesome? IPM works for them too. You must, however, be aware of laws that apply to nuisance wildlife and how they might affect  your IPM plan.

In New York, the regulatory players involved are the NYS Department of Environmental Conservation (all species) and the U.S. Fish and Wildlife Service (migratory birds and federally endangered and threatened species). Through these agencies, every wildlife species in the state has a legal classification. What is of upmost concern is determining whether your nuisance is classified as “unprotected” or “protected.”

Legal Classification: Unprotected

Unprotected mammals include shrews, moles, bats (except Indiana bats, which are federally protected), chipmunks, woodchucks, red squirrels, flying squirrels, voles, mice, and Norway rats. Unprotected bird species include rock doves (feral pigeons), house sparrows, and European starlings.

An unprotected species can legally be taken by the property owner at any time of year and by any means as long as other laws (i.e., pesticide regulations, firearm discharge ordinances, trespassing laws, etc.) are not violated. The DEC defines taking as pursuing, shooting, hunting, killing, capturing, trapping, snaring or netting wildlife and game, or performing acts that disturb or worry wildlife.

Some might consider it too cruel to take an animal and decide that capturing your nuisance pest with a live trap is best. Before heading to the hardware store, recognize that you cannot release an animal off your property without a permit. An unprotected animal can be released on the same property where it was captured or must be killed and buried or cremated.

Legal Classification: Protected

2 adult Canada geese and 7 goslings are shown feeding on a golf course.

Canada geese are protected by the Migratory Bird Treaty Act, but there are still things you can do to manage them. Harassing them (such as with dogs or lasers) does not need a permit. Interfering with their nest — such as addling their eggs — does need a permit. When in doubt, contact the DEC. Photo: Joellen Lampman

For some protected species, if an individual animal is causing damage (not merely being a nuisance), it can be taken by the property owner. Mammals that fall under this category include opossums, raccoons, weasels, and gray squirrels. (Skunks may legally be taken if they are only a nuisance, even if they are not causing damage.) But the animal, dead or alive, cannot be transported off the landowner’s property without a nuisance wildlife control permit obtained from the DEC.

A few mammals (including bear, beaver, deer, mink, and muskrat), most birds, and (currently) all reptiles and amphibians are not only protected but cannot be captured or removed from the property without special case-by-case permits.

Animals with a legal hunting or fur trapping season can be taken as long as the proper hunting or trapping license has been obtained.

Nuisance Wildlife Control Permits

Nuisance wildlife control permits are issued to people who have gone through the prescribed application process. These permits allow protected species to be taken in any number, at any time, and from any location — with permission of the landowner — within the state. Permits must be renewed annually. Private nuisance wildlife control operators, pest control operators dealing with nuisance wildlife, municipal animal control officers, and some wildlife rehabilitators must obtain the proper permits.

Laws change, so if you have a question concerning the legal status of a species or contemplated action, contact the Wildlife section of the regional office of the NYS Department of Environmental Conservation.

For information on IPM for nuisance wildlife, refer to Beasts Begone!: A Practitioner’s Guide to IPM in Buildings  and Best Practices for Nuisance Wildlife Control Operators.

Tick Checks and More — Stay Healthy and Happy While You’re Outside

Gardening. Hiking. Camping. The delights of spring after a tough winter. But spring also brings … deer ticks and the threat of Lyme disease.

Not every tick carries the bacteria that causes Lyme disease. But enough do to make proper clothing and even repellents an essential part of your daily outdoor routine — and careful tick checks (along with showers and clothes driers) an essential to your indoor

routine.

 

Ticks have a complicated life cycle, too — often catching the bacteria from infected mice, squirrels, chipmunks, or voles during their first year, then going dormant till the following year, when as adults they climb into high grass or bushes for their next meal, be it from a deer, a dog — or a person. Nor can they do without blood, because it’s what they need to lay their eggs.
