I won't go into what is right and what is wrong on this thread. It would take forever and I don't want to offend anyone, and its a friday!.
If you want REAL reputable information do the research:
www.cdc.gov
do a search for ticks:
Such as
Black legged ticks in Illinois, etc.
You can get maps of the latest vector species in your area, ID guides, etc.
Rocky Mountain, STARI, Lymes disease, Ehrlichiosis (which doctors ALWAYS MIS-DIAGNOSE.)
know what is in your area.
example
If you want real tick protection? Use permanone and be aware of what species are in your area, and what they transmit. Some species carry one thing, some carry others.
If you are going to take them off, use tweezers, grip as close to the skin as possible. Their saliva mixes with your body fluids to make a glue. Sometimes you can rib them out and leave the head in, so be careful.
PS: I'm an entomologist, this is one thing I know a ton about.
