I’ve got a bunch eating holes in my deck structure. I’ve built a trap, but none have ever gone in it. I’d rather avoid sprays. I’ve read I could spray the holes with a lemon juice concentrate. I posted a picture of the trap I go through but it doesn’t really work.
I used the spray from one of the big box stores. It filled their holes with a foaming insecticide. Once they were out and dead I filled the wholes with caulk.
