Re: why are there so many ticks
Stumps me. I thought they increased with the rise in deer populations. The army uses a product that has 5% permethrin. It works great for ticks and works for mosquitos and chiggers too. You treat your outer clothing with it but let it dry before wearing. It was very effective in the two worst tick hells I've been to, Camp Gruber Oklahoma and Ft Chaffee Arkansas. I've seen it at surplus stores, yellow can/green lid. Come to think of it they also have pouches of powder that you mix with water and dip your clothes in.
Marlin is right about the DDT. Platoon Daddy used to fog down the area where we would stop for the night and it works slick. Millions of people have died from malaria and other insect bourne diseases when the enviros pissed it away. I bet Al Gore didn't gripe when his platoon daddy sprayed down his cubicle, bunk and typewriter when he was in Southeast Asia.
Warte nur, balde ruhest du auch.
