After finding a couple of ticks after just walking in the lawn, I have
started wearing plastic grocery bags on my shoes, just tie them on. No
more ticks. I also am careful not to brush against trees or shrubs,
however.
Untie them when I get ready to come back inside, and reuse them a
couple times. We usually take cloth bags to the grocery store now, but
I'll remember to replenish the plastic bags now and then. Handy.
