Chuck,
How do you get their little legs apart? :-0
Seriously, I didn't know this would work for wasps, I've used it
successfully against rodents and skunks and the like.

Mothballs work because they exude poison fumes. No real mystery to it.
The poison is at such a low level that it doesn't bother large organisms like
human beings, (or so we want to believe) but the fumes make smaller critters
sick and away they go.

Dichlorobenzene (sp?) and some sort of naptha are the main ingredients in moth
balls. Don't eat one.
