They are very destructive!!!!

We had them and I was so afraid they were going to ruin our in ground
pool(its sand based). My dh managed to get rid of them(they probably
moved to the neighbors
.
) with some kind of "green" substance that
you put in the entrances. I will ask for the name and get back to you.

I DO have friends who lie in wait with a shotgun but that is not for us.lol.

I will let you know what he says.
