It is just less than a month from the time we had the pest control treatment from Pest Paramedics. However, the ants are seen crawling back this morning. And, in fact, I saw a lizard back on top of the kitchen ceiling. The man said it supposed to last two months while the advertisement says that it could be up to six months – guess not! In fact, the ant bait did not crowd any ants as mentioned by the worker.
