Parts of the north east have plenty of ticks. If I go huntin and its above 35 degrees I use a repellent with lots of deet in it, or a permethrin based repellent. Mainly for deer ticks. In mid to late spring deer ticks hatch out, and when they are in the nymph stage they are almost impossible to see, but they can carry the lyme bacteria. Adult deer ticks are also hard to detect but are more noticeable. they are still nowhere close to the size of a dog tick which does not carry lyme decease, but can carry other disease's.
Ticks have a knack for crawling on your skin with out you being able to feel them. Also most of the time you can't feel the bite either. They crawl until they find a warm area, like under arm pits, crotch area, and in your hair on your scalp. They attach and feed on your blood until full, then drop off. Lyme disease is something you don't want to get. I was treated for lyme for one year with oral antibiotics, including six weeks of intravenous with a pick line. This was 12 years ago. I still have the lyme bacteria but I guess my immune system kind of controls it. I have had to take two, four month periods of antibiotics since I was first treated. The last one was about a year ago.
If caught early Lyme can be beat. 40% of people that get lyme never notice the bulls eye rash around a bite. Or notice a tick attached to them. I guess I fell into the forty percent. If you would happen to see a bulls eye rash, I would get a one month prescription of antibiotics. Most doctors only want to give a one or two week prescription. Believe me there are not many doctors that know how to treat lyme or know anything about it. Or are there insurance companies that let doctors treat it the way it should be. If you do have a deer tick attached, remove it with a very small pair of tweezers, as close to the skin as possible then send it to a lab that will test it for lyme.
The best repellents to use are permethrin based, and kill ticks on contact. These repellents are not to be used on skin, just clothing. A couple brands are Duranon, Repel Peromanone, and Cutter Outdoorsman Gear guard. Deet based can be used on skin, but do not kill ticks they are just a repellent. Its also a good idea to keep your pants tucked in your boots.
I have a hard time spring gobbler hunting anymore, sitting on the ground, without thinking about ticks crawling up my back. If fact I don't do much spring gobbler hunting any more because of this thought.
