Curious what the average tick pest control treatment costs? Find out how much tick treatments should cost and what you can do to minimize your chances of having ticks on your property.
Have you ever wondered if ticks survive in winter? Cold weather can make us question the survival of many insects and small creatures, including ticks. In this article, we will explore how ticks manage to thrive during the winter season.
Though it might seem unlikely, ticks can actually survive despite freezing temperatures. They have various strategies to adapt to the cold environment, such as seeking shelter in leaf litter or tall grasses. So, during winter, you should still be cautious and take preventative measures to protect yourself and your pets from ticks.
While some tick species may show a decrease in activity during colder months, others like the blacklegged tick can remain active even when temperatures drop below freezing. These ticks protect themselves by producing a type of natural antifreeze substance, allowing them to survive and search for hosts throughout the winter. So, be mindful of ticks and stay safe even when the snow starts falling.
Ticks and Their Ability to Survive Winter
General Survival Mechanisms
Ticks are resilient creatures and can indeed survive during winter, using a variety of methods. One way they achieve this is by becoming dormant, hiding in leaf litter or tall grasses to escape freezing temperatures.
Since you may think that ticks are inactive in the cold, it’s essential to remain vigilant even during winter months. Ticks can still pose a threat if they find a suitable host like you or your pets who can provide them warmth and a blood meal they need to survive.
Cryoprotectants and Diapause
Ticks have fascinating physiological adaptations that help them endure frigid conditions. One such adaptation is the production of cryoprotectants. These are substances that assist in protecting the tick’s cells from damage caused by freezing temperatures. Cryoprotectants work by preventing the formation of ice crystals within the cell, allowing ticks to maintain their functionality in the cold.
Another survival tactic employed by ticks is diapause, a period of dormancy similar to hibernation. During diapause, ticks undergo a state of suspended development, conserving energy and reducing their metabolic rate. This strategy enables them to withstand harsh environmental conditions and survive until the temperature becomes favorable again for their life cycle to continue.
In summary, ticks are hardy creatures with unique adaptations that enable them to survive, even during the winter months. It’s crucial to remain vigilant and take necessary precautions to protect yourself and your pets from potential tick-borne diseases throughout the year.
Impact of Weather and Temperature on Ticks
Ticks in Freezing Temperatures
Ticks are resilient creatures that can often survive in freezing temperatures. They rely on snow pack and leaf litter for insulation during colder months. Deep snow can provide a protective layer, allowing them to avoid harsh conditions.
Despite this, extremely cold weather still impacts tick populations. Studies indicate that ticks can die at temperatures between -2 to 14 degrees Fahrenheit. However, most ticks can still survive winter, with only around 20% of their population dying off.
The Effect of First Frost
The first frost can slow down tick activity, but it doesn’t necessarily kill them. When temperatures drop, ticks tend to become less active, which may decrease their chances to find a host. This temporary reduction in tick encounters helps lessen the spread of tick-borne diseases during winter.
Nevertheless, it’s essential to stay cautious, as ticks can still be found under leaf litter or other vegetation, waiting for a warmer day.
Adapting to Warmer Climate
Warmer climate conditions, due to climate change, can affect tick populations and increase tick-borne disease risk. As ticks spend most of their lives away from hosts, they are expected to adapt to changing conditions.
In a warmer climate, ticks may:
- Have a shorter life cycle
- Emerge earlier in the year
- Expand their range
- Increase the prevalence of diseases they transmit.
For example, black-legged ticks can complete their two-year life cycle in less than 12 months if the conditions are right. These changes can lead to a higher tick population density, posing a threat to human and animal health.
Overall, changing weather patterns play a significant role in tick survival and behavior. Regardless of climate conditions, it’s crucial to stay informed and take precautions to avoid tick encounters and the transmission of tick-borne diseases.

We just found an American Dog Tick on my sister yesterday. It was flat as a pancake, so it was obviously a hungry tick. For some reason, people around here find more ticks on themselves than on the dogs they walk. I think that may be due to the flea drops people give to their pets, because some brands claim they repel ticks as well. I’m not sure if it’s true or not, but it sure would explain a few things.
Tick!
Dog tick.
Also, it’s possible you didn’t get the head out when you ripped it off. Ask a doctor to check it for you.
I have been bitten by a black bug, looks like a raisin,with legs, after it bit me it looked more brown with red tint , it leaves a big bite mark a chunck out of my skin, witch goes into a welt as big as half the size of my palm ,and gets hot painful and awful itching . it bite is painful and quick them repeats bite , and is gone so quick it has taken years to see one . I live in Ohio any idea what it is ?
Possibly a Bed Bug.
Not a bed bug to large, it was black, looked like a raisin with legs, and was the same size of a raisin , leaves a large bite, and takes a chunck ot of my skin. It bites quickly and mulity bites and it hurts ! Always bites me when I am on my sofa several times a year ! Can’t find any trace of this bug !
I have never seen a tick this color and shape in our area. I have to assume it came in on our sweet collie. I will be getting Frontline for her tomorrow so the fleas and strange ticks, well all ticks, stay off of her! Gross!
I thought this was a rock in my house till it squished and noticed the legs. Same thing as picture. What stage is this, should I be worried it laid eggs in my house. Also curious what the bite looks like. I dont see any marks on myself and checking dog for any others.
Probably some kind of mite. Unless OP can take to local veterinary clinic, they might put it under a microscope for free to see what it is and they might have a camera to that microscope or you could put your phone camera lens to the eye piece and line it up just right to see. Good luck!
I’m sure the dime was put next to the “black speck” for scale. I’m surprised with the seemingly flippant response from What’s That Bug.
While the photo is not that clear, it could be a deer tick.( Ixodes dammini or Ixodes scapularis ). It has been a particularly bad year for those of us living in an endemic area (which is growing year by year). I’d take Toby G.’s advice (above in comments). Good luck, indeed!

If you are not familiar with Ticks, please research them a bit. Having them around is not good news. They carry some bad diseases to humans and dogs.
Don’t want to create a panic but it should be said that those carry two bad diseases, Lyme disease, and Rocky Mountaiin Spotted Fever. If that tick bit you enough to draw blood see a doctor for either disease.
Any time you hike in wooded areas check your entire body for these bugs after the hike.

I need help fast none of my family believes that I have a problem with a pearasites in my body because ALL THE test are coming back negative now it’s been so long I can see things in my stool so sorry but more from my lungs
What are the health risks for dogs and humans? We found an engorged tick on our maltese.
Having had myself, relatives and dogs bitten by ticks, and some of them having been diagnosed with lyme or suspected of having some one of the many tick bourne diseases, I would like to share this website with you for tick i.d.. You can submit your photo to them.

Dogs get stuff just as easily as people. Depending on the immune system, any symptoms can take a week or 6 months or more to show. Disconcerting to know the ba#&%&d@ can be active in winter! You’re the 2nd one I’ve heard of this year. Take care.
