Hi Thanks for mentioning this. Also, if you don't want to find dead ants all over the oven, put a pan of hot water ( with a little soap added ) under the object. When they come out, they fall in. The soap or detergent makes sure they drown. This heating method also works for termites. Some exterminators actually tent the house in an insulator and just heat the house. To bad that is doesn't kill dry rot. Dwight
