Whether you use a chemical t/x or not, the best thing is to be observant; checking for ticks upon coming indoors.

Only a small % of ticks are carriers and they must engorge before they deposit their infectious saliva (to keep wound open). It may take a tick over an hour wandering around before they find a place to bite and it takes more than a few hours to engorge.

I get using chemicals but even w/out there's not too much risk of infection for the overly cautious.
