You also must remember that the lyme disease enzyme is released by the tick when it removes it's self from the host (generally after three days of feeding). So even if you find a deer tick on you 1. It may not carry the disease and 2. If you remove it soon, EVEN if it has the disease it may not get to transfer the enzyme.

That being said,I still hate them and load up with deet whin I go in the woods during tick season.
