W.C.
I had ants at one of my ants, and I have some really bad news for you. For every ant you see, there are 25 ants you don't see. Yuck!
They were in my dishwasher, my stove, my counter, and my sink....and I had babies. My husband could care less.
I finally told him, it was the ants or me. Make a choice. Then we got an exterminator to take care of it. Hah!
They came out once to do the inside and did the outside once a year. Then I stopped the service. They were back in a month. d_ _ _ buggers! So I had to resume the service. Just outside.
They do have the chemical now available on the market but I wouldn't touch it--let the pros do it.
