Ticks commonly overwinter by ‘nesting’ in groups; taking refuge under the soil, ground litter, and snow cover which acts as an insulating blanket, sheltering them from the frigid winter temperatures. When warmer weather arrives, they position themselves on vegetation and wait patiently, front legs outstretched, for any warm-blooded ‘host’ to pass by; a behavior known as ‘questing’. When one does, the tick latches on and soon begins taking its next blood meal.

‘Tis the season to hit the trails. At the same time, all outdoor enthusiasts hope to avoid the worst of all biting insects: The tick.
Here are a few selections from the Almanack archive that address these most-maligned insects:
From 2017: In a personal take on ticks, Tim Rowland writes: “I’d always viewed ticks as benign, but now I have to put them into that “one more thing to worry about” category, which is already quite an overcrowded field. After a recent hike in Essex County I picked two of the bastards off of me, and of course it happened in the middle of the night when everything seems more dramatic than it is. So where previously, I would never have given it a second thought, I instead lied awake for an hour wondering, ‘Am I doomed?'”
Anyone paying attention to the rapid rise of tick-borne diseases has heard the advice on avoiding tick bites. The advice we are hearing is not wrong, just very incomplete.
Most information to the public suggests wearing light colored clothing, tucking your pants into your socks, and checking your body carefully after possible exposure. The intent is to keep ticks away from your skin, and to remove them promptly if they succeed in attaching. This was sufficient when Lyme disease was the only real worry, since research has shown the Lyme disease organism is not transmitted until the tick has been attached for hours.
Getting fresh air is more important than ever this coming summer during the public health crises, but it would be wise to remember that both ticks and people are going to be active and outside. Laura Harrington, a professor of entomology, vector biologist, and Director of the CDC Northeast Regional Center for Excellence in Vector Borne Diseases (NEVBD) has shared some tips on how to avoid ticks.
A bacterial infection that causes Lyme disease is the most important tick-borne human infection in the U.S., with around 200,000-300,000 reported cases per year. The blacklegged tick or ‘deer tick’ is the vector of Lyme disease in most of the U.S. It can also transmit other pathogens to people and pets, including the agents that cause babesiosis, anaplasmosis and Powassan disease. Blacklegged ticks are most common in forested areas and shaded trail edges with abundant leaf litter and shrubby plants, Harrington says.
Harrington recommends a few personal protection measures to keep ticks from biting, such as tick repellent, first and foremost. She also recommends light-colored clothing, and to tuck your pantlegs into your socks. It also wouldn’t hurt to treat your clothing with permethrin, or to purchase permethrin-treated clothing. Remember to check yourself for ticks often as well, both while hiking and after you get home! It only takes 24-48 hours after the tick attaches before it can begin to transmit Lyme disease. For other pathogens like the Powassan virus, transmission can happen quickly, so it is good to check as often as possible.
Check for ticks all over your body, including your back, neck, and hairline. If you happen to find a tick, carefully remove it with sharp tweezers by grasping as close to the point of attachment as possible and pulling. Once you are back inside, place your clothes in the dryer for at least 20 minutes, and take a shower (a good place to perform a tick check). You can also place your clothes in a sealed garbage bag to dry later.

Black flies bite, but ticks really suck. Enough complaining – that never helps.
After such a long winter, we are all grateful that spring has finally sprung, even though the price of warm weather seems to be the advent of biting insects. Swarms of mosquitoes can drain the fun from an evening on the deck, but a single black-legged or deer tick (Ixodes scapularis) can take the shine off an entire summer if it infects you with Lyme disease and/or another serious illness. » Continue Reading.
Eighteen years ago, when I moved back to New Hampshire, I rarely came across ticks. The dog didn’t carry them unwittingly into the house, and I could spend the day in the garden or on wooded trails and not see a single, hard-shelled, eight-legged, blood-sucking creepy-crawly.
Not so anymore. Now, from the time of snowmelt in the spring to the first crisp snowfall of autumn – and often beyond – we find ticks everywhere: on the dog, crawling up the front door, along kids’ hairlines, on backs or arms or legs, and occasionally (and alarmingly) walking along a couch cushion or bed pillow. » Continue Reading.
I’d been living in the North Country for about a month when I woke up to discover a red bulls eye on my left arm. Since, mentally and emotionally, I have never advanced much past the fourth grade, my first thought was: “Cool!”
Because it was clearly visible, however, a number of people subsequently pointed out that this, technically, was nothing to celebrate. So I walked around for the next three days looking like the dog from the Target ads, while people dutifully commented on my impending doom.
Nothing ever came of it. So far the only discomfort ticks have caused me is embarrassment, owing to an appointment with a massage therapist that went horribly wrong. » Continue Reading.
Years ago I read an author interview, and although I don’t recall her name, one of the images she raised has stayed with me. It’s not an exact quote, but she said something to the effect that writing ought to feel to an author as if they were water skiing behind their work, not towing it like a barge. In general, I find this to be the case. The hours or days of research which go into an article are hardly exhilarating, but the wave-jumping that comes after shrinking those pages of facts into 800 words makes it worth the effort.
However, when I tried to water-ski behind a brand-new invasive tick that can reproduce without mating, drain the blood out of livestock, and potentially carry ten or more human diseases, including one similar to Ebola, something changed. A few topics whip across the water at high speed. Most at least pull me at a leisurely pace. This one made me drop the whole water skiing idea and swim for my life. Turns out there is a limit to how many miles you can get out of happy imagery. And to how long a writer should be allowed to spend alone in a room with the same metaphor. » Continue Reading.
Over the past few decades, black-legged tick populations have grown relentlessly. These are the ticks that carry Lyme disease, and so what was once a novelty illness has become a rite of passage for many. It’s probably safe to say that by now everyone reading this knows someone who’s had the disease, if they haven’t had it themselves.
But some years are worse than others when it comes to Lyme disease infection rates, so the obvious question is: what causes this? Part of the answer involves the number of deer and small mammals around. There’s been elegant science done that establishes a neat connection between Lyme disease rates and good acorn years. The oaks produce a good crop, which causes a spike in the mouse and chipmunk populations the next year, and then a surge in human Lyme disease cases a year after that. » Continue Reading.
With the warm weather here and more opportunities to spend time outdoors, it’s important to remember these tips to prevent ticks from affecting your summer. Be sure to protect yourself, pets and your property from ticks.
The most effective way to avoid ticks when outdoors is to avoid contact with soil, leaf litter and vegetation. However, if you hike, camp, hunt, work or otherwise spend time in the outdoors, you can still protect yourself. » Continue Reading.
I’ve been asked on four different occasions, recently, how tick populations will be impacted by the December/January below-zero cold. Some of those asking had heard reports, apparently claiming that tick populations would be decimated, if not eradicated, by the prolonged period of extremely cold weather.
We’d all certainly welcome that. It’s probable that you or someone you know has been affected by ticks and/or by Lyme disease. And any downward pressure on tick populations is welcome. But, the answer isn’t that simple. » Continue Reading.
On a hike this spring, we walked through a clear-cut area with tall grass and brambles. Afterwards, our pant legs were crawling with black-legged ticks (Ixodes scapularis), also known as deer ticks, the kind that carry Lyme disease. Scientists with the Vermont Department of Health recently examined over 2,000 ticks and found that 53% of black-legged ticks tested positive for Lyme disease. A small percentage of the ticks carried pathogens that cause anaplasmosis or babesiosis, two other tick-borne diseases that can make people gravely ill.
Understanding the two-year life cycle of the black-legged tick can help prevent Lyme disease. In the spring of the first year, tick larvae hatch from honey-colored eggs in the leaf litter. The six-legged larvae, about the size of a poppy seed, soon seek their first blood meal. The larvae may become infected with the bacterium that causes Lyme disease through this blood meal; it all depends on what kind of animal they find as a host. If it’s a white-footed mouse, they’re very likely to contract the Lyme spirochete. If it’s a chipmunk or shrew, they’re somewhat likely. If it’s a squirrel or a larger mammal, they probably won’t. » Continue Reading.
The loathsome deer tick, also known as the black-legged tick, is defined more by the disease it spreads than by its own characteristics. Deer ticks, a name that came about due to its habit of parasitizing white-tailed deer, are transmitters or vectors for Lyme disease microbes that they acquire by feeding on infected mice and rodents. Lyme disease, if untreated can cause a variety of health issues including facial paralysis, heart palpitations, arthritis, severe headaches, and neurological disorders. According to the Centers for Disease Control and Prevention, Lyme disease is currently one of the fastest-growing and most commonly reported vector-borne diseases in the United States. More than 14,000 cases are reported annually, but because the symptoms so closely resemble the flu and usually go away without treatment, scientists estimate as many as nine out of every ten cases go unreported. » Continue Reading.
