Nippon was placed on kitchen floor Thursday night. My Son and I watched in amazement as the line of Ants started coming out of a tiny hole in the skirting board next to the back door taking the bate and returning back through the hole. We were feeling very guilty. Half an hour later a steady stream started coming through the hole. Last night there was not so many. The instructions said to leave it down for 7 to 10 days. It is sad having to do this but hearing of the distressing problem the Ants have caused for some of you, it is a problem that I need to deal with. I shall keep you all posted. Thank you All again.
