Ants in Washington

Washington ants build tiny mounds in lawns in the warmer months of the year. But one should not be fooled by the small size of the mounds. They could house tens or hundreds of ants.

The common big black ants of Washington State are the biting carpenter ants, while the small black ant species native to the state is the odorous house ant. If you see black ants with red heads in the state, they are likely to be the western thatching ants.
