Controlling Moisture ants

Carton nests resemble hard clods of soil and may be fashioned around areas such as plumbing pipes, sill plates, or wall studs. You may not notice a moisture ant infestation until you open up a wall or see the winged reproductive swarm, typically during late summer in the Pacific Northwest. This can cause homeowners to panic when they see the winged ants pouring out of a window sill, kitchen, or bathroom. 

Moisture ants frequently build their nests in previously damaged wood. But some moisture ant colonies make their nests against the foundation of homes. Their tunneling can cause further structural damage when ignored. If you have a moisture ant problem, it is likely a secondary symptom to an underlying issue with moisture damage that requires remediation.

Chemical pesticides alone will not get rid of a moisture ant infestation. However, periodic applications can definitely slow them down until a more permanent solution can be made. It is recommended to remove the source that has attracted them, like rotting wood, and replace the damaged material to completely rid your structure of moisture ants.
