We have had ants indoors year-round (summer more so) since the beginning of time in our very old old house and we’d always had numbers low’ish enough that little barriers of Diatomaceous Earth placed strategically with the occasional massacre using bleach water seemed to keep their numbers low enough where we could co-exist. Until the year before last and it was unreal. We felt like we were under siege! We tried what felt like everything non-toxic but the invasion seemed to keep intensifying. My partner would follow the single file lines of troops back to where they were centralized, bleach down the area and re-caulk or paint, or plug the hole but they’d just find another. Ian (lost his poor mind) finally hunted down the two entryways outdoors that they were using. Instead of blocking, now continually keeps little jars (those tall skinny caper jars work really well) no lid, laying on their sides with a mix of sugar and borax inside right at the entry spots (one in front of the house and the other is in back). We still see an occasional ant traipsing down the edge of a counter or up a wall, but our experience keeping the bait outdoors has been a game-changer and a mind, soul and life-saver!
