Carpenter ants got that name because of the tunnels they create in wood when building nests. They don’t eat wood, but their tunneling is the cause of significant structural damage to homes when not taken care of. They are typically black in color, and if you can’t spot the ants themselves, you may be able to notice piles of sawdust or insulation from their tunneling or small openings in the wood of windowsills and other areas close to your home’s exterior.


Odorous house ants are known best for the sour, rotten smell they release when stepped on or smashed. They are very small, typically under ⅛ inches, and are brown in color. They are attracted to moisture, and you may find them near leaking pipes or heaters.


Moisture ants are similar in size to odorous house ants and are dark brown or yellow in color. They can build large, disruptive nests and are attracted to moisture just like their odorous cousins, so you may find nests built near bath tubs, in damp crawlspaces, near leaks in your roof, or near windows.
