For example, they found a small hole (about the size of a quarter) in my wall that was drilled slightly too large when running a pipe to my AC condenser and a crack under my front steps. The exterminators will seal all but one of the holes by stuffing stainless steel wool into the holes. At the single remaining hole, they will place old fashion snap traps and monitor the hole for about a week, and then fill up that hole as well at the end of the week. Evidently, mice do not make holes by chewing (rats do), sealing is effective to keep them out.
No poison was used because you don't want dead mice rotting in your walls/ceiling.
Who is your exterminator? I called one who came and insisted he had to set poison around our entire house, inside and out, to catch the mice. I told him we had a dog who liked to eat things, and that we didn't want any poison, but he said there is "no way" to kill all the mice in my house without poison!!
I didn't hire him. Instead I bought some copper netting and stuffed it into every crack and crevice from ground level to about 2.5 feet above the ground. I set a gazillion spring traps inside the house and caught about 12 mice. Yetch. But the following year, we had no mice because we'd killed all the ones inside the house, and no new ones could get inside. No chemicals, no poisons.
But, PP, I love your exterminator's approach too! So, please tell us who he is!
