Thatís just about the life cycle, give or take, depending on local conditions. And sometimes itís just easier to screen them out using insect screening, depending on where they are.
But if you can get to the galleries, you kill a female drilling her gallery by using the WD-40 directly in the hole. Inactive holes poke with a wire then ram cotton balls (soaked in xylene) into the galleries. After a few days, fill the galleries with plastic wood or caulk. You can do all this anytime, and you can do it in the daytime.
