I"m a HUGE Google fan.
Gotta Google it if I don't know the answer.
So, of course I Google'd this.
There are loads of people who try this and swear that this actually works.
One says it works for bees too.
I wonder if it'll work for the wasps we have that are always flying around and making nests in our windows.
Guess when it stops raining, I'm going to set out some baggies with pennies in them.
