RE: tick repellent
am in chemistry - only product I know of for clothes is Permanone and has Permethrin in it. Spray clothes - do read the product label carefully and it does help.
On skin repellent products that conatin deet do work to a limited extent.
Again read the product label.
On returning home or putting away clothes in the truck or vehicle. I bag them in a big plastic bag and spray any ole house and garden insecticide and then close the bag tightly. This will help kill anything hiding in your clothes.
Or put in a dryer at a hot setting for 10 minutes. Now make sure you have emptied out calls and shot shells!
Ticks are the only critter I know of that makes one get naked as ya can't see everywhere on yer body!
