How do I get rid of flying ants in my house?

The best way to get rid of flying ants, or carpenter ants, in a home is to locate the nest, drill 1/8-inch holes into the wall and inject desiccant dusts such as silica gel, diatomaceous earth or boric acid directly into the nest area. Because indoor nests often originate from parent colonies outside, these outside colonies should also be searched for and eliminated using commercial insect spray.
