Never had trouble with those for using vinegar to remove ant trails. If you've got aphids and fruit flies getting in too, maybe that's the first thing to solve!

Never had trouble with those for using vinegar to remove ant trails. If you've got aphids and fruit flies getting in too, maybe that's the first thing to solve! As for the rest, I certainly don't imagine it working all the time everywhere, but for the local pavement ant colony's roughly annual sortie into my kitchen it's fine. And what do you find of idealism in my not wanting to poison the room I feed myself in?
