When I was in Marine boot camp in Parris Island, SC, the mosquitoes were brutal and our drill instructors recommended that we have our family send us Avon Skin-so-soft.
I must say that my father was wondering just what sort of outfit his son had joined!
The stuff did seem to work well.
A few years ago, I put some bat-houses in the woods behind my yard - that seems to have cut down on the mosquito population quite a bit. Wish there was a way I could breed dragonflies. The average dragonfly will consume up to 50 mosquitoes a day.
Dab some tea tree oil here and there when working in the garden. It smells like terpentine and no bug will approach without a gas mask. lol!
