We live in tick country (NH) and do a tick check every single evening if we’ve been outside that day.
If they’re not embedded the most sure way of removing them from the gene pool is a piece of scotch tape. Put it on their back and they stick to it, wiggling their little legs helplessly in the air (love it), and I fold the tape over, seal it together around the edges, and toss it in the trash. They cannot get out of the sealed up tape.
Even the ones we pull off get the tape treatment, but we put them there.
Did the same with fleas. Works great.
