Lymes disease, carried by deer ticks, is endemic in the NE USA. Advice for anyone doing a lot of hiking - 1 get a device for removing ticks. 2 Treat all of the clothing regularly used for hiking, and camping equipment (paticularly hammock, but also tent)_ with Permethrin. Dip all clothing etc in a bucket of permethrin solution, hang to dry. It is claimed that this will last about 6 washing cycles before it needs to be repeated. Just about any insect that comes in contact with the treated material will die. This is also protection against Mosquitoes, which is why one should treat the hammock.
Permethrin is a synthetic analogue of a natural insecticide produced by chrysanthemums.It is a neurotoxin and it is probably best to keep the aqueous solution off your skin by using rubber gloves and being careful. It is particularly dangerous in the aqueous phase to cats , so care must be taken to keep cats away from the drying clothes & materials. Some will no doubt say that use of powerful chemicals like permethrin is dangerous. I have seen people in late stages of Lymes disease. That is far worse, and the chemicals used for treatment are many factors more dangerous than preventative action with permethrin.
Spray bottlesof permethrin solutionare sold otc at most US outdoor stores. Stronger solutions used to make soaking baths are readily available in agricultural supply stores (used to dip/spray cattle and horses). The latter is much less expensive, as a litre bottle (32 oz) will last many seasons.
