we have a problem with ticks here in southwestern Wisconsin. Naturally we wear very light colored clothing. The sprays I use don't seem to deter the wood ticks and normally have several on me each time i go out. One time after leaving the cabin drove two hours stopped at a McDonalds and the guy in line behind me taps my shoulder and says "hey you got a tick crawling around on your neck"
Must have picked it up while walking to the car and it was crawling around on me while I drove. Worst is picking them off your buttocks while showering...not as limber anymore.
Thankfully have not had an experience with a deer tick. Cedar chips might help around the house.
