Girl strips don't work so well.  Fly strips do ok but should be removed before entering a restaurant.

Girl strips have always had the wrong kind of girl stuck to them and that is a load to carry.

In honesty, for the ankles and perhaps around sock areas, sulfur powder will help keep off some crawly critters.  I wear this when in 'fire ant" territory down in more southern areas.  I don't recommend a sulfur dusting of the body, just the ankles for crawly things.        Tom.
