My house used to get INFESTED with house centipedes in the spring and fall - we’d find 1-2 a day, and not just in the basement or ground floor of our house, but in our BEDROOM. We re-did our backyard, tearing out the deck that connected to the house, and found that the grading of the backyard underneath the deck actually drained water TOWARDS the house, resulting in lovely dark and damp conditions that house centipedes absolutely love. Since we got rid of that deck? We now only see maybe 1-2 a month in the busy season. I’m not sad to see them go, and haven’t seen an uptick in spiders or other buggies either. So I’m guessing all that damp under the deck was also a nice breeding ground for all those other bugs too.
Edit - despite being so infested with them, nobody in my house was ever bitten by a house centipede, for what it’s worth.
