Here is my take on this. The widely available product Repel contains permanone.
This is a very effective tick repellant for all kinds of ticks. Read the label and use as directed. Personal examination for ticks after being out of doors may reveal unattached or attached ticks that can be properly dealt with. For mosquitos Deet products are good. Be careful with repeated applications of 100 % Deet products on hot sweaty days, it can affect your nervous system when overdone. You can't live in fear, but awareness and proper preparation can greatly reduce your risks as in most any endeavor. We have both Lyme disease and West Nile in our area and camp all season.
