Odorous House Ant
This ant can be difficult to control because it establishes multiple subcolonies and may nest in such a wide variety of sites. The keys to control are to find the colonies and subcolonies and treat them directly.
Where the colonies cannot be found, baits may be attempted; however, several baits may be required before positive results are seen. Regular inspections and service are necessary to find and treat new colonies as they move in from neighboring properties.
Eliminate piles of lumber, bricks, or other debris that could serve as a nesting site for ants.
Keep landscape mulch less than 2 inches thick and at least 12 inches away from foundations.
Ensure the sprinkler system does not spray directly onto the foundation.
Seal as many cracks in the home’s exterior as possible.
Keep tree and shrub branches trimmed to prevent them from touching the building.
