Yes, after THREE visits from the exterminator, we STILL have ants. These are the most resilient ants I have ever seen! The exterminator is coming back for a fourth time next Tuesday. If they don't kill them this time, is it wrong for me to expect a refund so I can call another company?? I paid $350 for this 6-month GUARANTEED service and I got nothing!! Ants in my tub, ants in my bedroom, ants in the hallway, the living room, ants in the kitchen!! I kill about 15-30 ants every day!! I have to sweep up their little ant carcuses every morning and every night!! I kill them with my bare hands and feet!! It's disgusting. And we're not pigs, my house is clean and we don't have food lying around - the kitchen counters are wiped down several times a day and there are no crumbs about at all. It's so frustrating. Ugh, just had to vent.
