I use to get them all the time. Then I started using a product called Amdro. It goes around the perimeter of the house outside. I also used the chalk around the perimeter of the house and drew a chalk line. Then I drew a chalk line around my kitchen window where they seemed to be coming in. In the fall I washed the inside chalk line away.I used windex or a similar product on the counters and that killed them if they were there.
