Soak your hunting clothes in Permethrin. Keep pants tucked in socks or wear gaitors etc.
Carry a lint roller in your car and give yourself a good roll down. Better yet, have your hunting partner roll you down.
At home, all hunting clothes go in the dryer for 20-30 mins on high. That roasts the little bastards.
Some of us have Permethrin threated cover-alls that we wear in the woods. At the car, lint roller treatment, cover-alls off and into plastic trash bag. At home into the dryer they go. So you know this is for heavily infested tick areas. In these areas trail blazing hikers wearing untreated clothing have come out of the woods with hundreds of deer ticks crawling on their clothing. Dozens are not uncommon for a short hike. Permethrin knocks that down to a just a few ticks, but since it only takes one, that's a few too many.
Hard frost will drive them underground. However, days above freezing some could some out for a look/see.
They are programed to climb up. They will climb up on high grass, low branches and low scrubs. Most are located within a foot or two of the ground as that's where their hosts are. However, unobstructed they will climb higher. I've found tick infested leaves six feet off the ground. Unusual, butt?
Best prevention is to know their habitat and avoid it.
Once they've hitched a ride on you they will also climb up looking for moist warm spot to latch on.
Transmission of Lyme, if bitten by a deer tick, takes hours. That's after taking hours for it to find a place for dinner. So, if you find one don't panic. Keep an eye on the bite. Also, keep an eye on your health. Lyme takes a about a month to reach critical mass. Even if you didn't get a bullsye rash, if you start feeling flu like symtoms 3 to 5 weeks down the road, time to get a blood test. BTW, the blood test is useless less than month after the bite as Lyme won't show until it's had time to grow.
However they do seem to be less active in January.
