You need (perhaps multiple) dehumidifiers. Keep at 40-45% rel.hum. and silverfish will disappear. Don't keep food unsealed (looking at you: unwashed dishwear)

You need (perhaps multiple) dehumidifiers. Keep at 40-45% rel.hum. and silverfish will disappear. Don't keep food unsealed (looking at you: unwashed dishwear) and cockroaches will disappear. Have neither and centipedes will disappear. ---- No advice for bedbugs other than Diatomacious Earth and not bringing in used furniture / houseguests.
