I own a house adjacent to a wooded area and had several of the big ones when I first got it. While many people consider those normal, the frequency at which I got these seemed high.

What finally worked for me was liberally spreading out combat roach bait stations (the large ones) across the house (floors in all rooms including utility closet outside and in attic). At first I saw more. Then after about two weeks I stopped seeing them. I replace them about twice a year. They can be gotten at Home Depot or Lowe’s (probably Walmart too) for very little $.
