I highly recommend WD-40. Kills them almost instantly. Just spray it in the holes and they will back out and die. I've kill a bunch of the on and around my kids swing set.
Thanks for letting me join the group! I've been looking around here awhile know. I just happened to see a guy who needed help and thought I could give him a option. Thanks again
I use the same machine as what's one my classic car. The machine works great for all kinds of paint removal. From car to decks to houses. The process used recycled glass with water. So you have the benefit of water to keep the dust down and the action of a pressure washer with the added benefit...
Give me a call. I live in Evansville. I own a dustless blasting machine. I think I could help. My name is Jason. Call me 812-499-9345. Thanks. Good luck with your project!
