How to stop ants coming in the house

Updated February 21, 2017

While ants do not carry communicable diseases like other pests such as mosquitoes, they can still be bothersome, particularly when a colony moves into your home or just outside it. The best way to avoid becoming overrun with ants is to prevent them from getting into your home in the first place. By taking care to seal and properly clean your house, you can greatly reduce the likelihood of an infestation.

Use caulk to seal any openings and cracks that go from inside your home to outside. Cracks in the walls and improper seals around windows provide passageways for ants to gain access to your home.

Spray around the exterior of your home with long-lasting insecticide sprays. These sprays will create a barrier, which ants cannot cross without dying.

Search around the exterior of your house and locate the ant nest if possible, then spray with insecticide. Spraying the nest will kill a large number of the ants.

Clean your house thoroughly and keep it clean. Clean up food spills immediately. Avoid eating in bedroom or living room. Crumbs attract ants to your home as potential food sources.

Set baited ant traps near areas where ants are entering your house. The traps do not kill the ants instantly, rather they take some of the toxic bait back to the nest where other ants feed on it and eventually die.

Hire a professional exterminator if the problem persists. Exterminators will destroy the infestation, allowing you to control the problem in the future by following the previous steps.
