On a recent visit from our pest company, they mentioned that we really need a plant free border around our house. Plants that touch the side of your house allow bugs to get past the pest spray. We removed almost all of our plants and cut away the grass, creating a 2ft wide border around the house. Then we put weed cloth down, installed plastic edging, and added a good layer of bark. Now when the pest guy comes, he can easily spray along the foundation.
I'm sorry. Unless the bugs are life threatening or at least pose a major problem, I will keep my foundation plantings and any bugs that might escape my Malathion spray.
We struggle with serious carpenter ant infestations so we had to go this route. It was not what I wanted but it became necessary to effectively get rid of them. :(
Very important added information. Thank you.
