FLU is right. They want water. Doesn’t matter how clean you keep your house. They’ll find a spec of something and they’ll be on it.
Tell that to the ants around here. We live in CV and don’t have an ant problem, because we keep the house clean. We leave water out for the dog, have damp potted plants around, etc., but no ants. Leave food out for a couple of days, then they show up.
If anyone wants to lead ants outside with food, try a small pile of sugar.
