How Do Ants Get Inside Your House?

What Attracts Ants to Come Inside?

Ants invading your home can be a persistent nuisance, whether seasonal or year-round. These tiny pests are drawn indoors by several factors:

  • Food Sources: Ants are drawn to sweets, meats, starches, and liquids—just like humans. Even small crumbs or spills can be enough to lure them inside.

  • Moisture: Many ant species actively seek water sources, especially during dry periods. Leaky pipes, condensation, or even pet water bowls can attract ants.

  • Shelter: Ants often enter homes in search of protected spaces to nest, such as

    wall voids, areas under appliances, behind window frames, and beneath floors.

While some ants merely forage indoors and return to outdoor nests, others may establish colonies inside your home. Common indoor-nesting species include pavement ants, carpenter ants, odorous ants, thief ants, acrobat ants, and the notoriously difficult-to-control pharaoh ants. Ant activity typically peaks during warmer months in most regions, but in southern states, they can be a year-round issue. Understanding how these persistent pests find their way inside is the first step in preventing an infestation.

How Do Ants Get Inside?

Ants are incredibly resourceful when it comes to getting into homes. They can slip through tiny cracks in foundations, gaps around windows and doors, utility line openings, or damaged seals. In fact, they only need a space as small as 1/64 of an inch to find a way inside. Ants often use hidden routes like wall voids and subflooring or even hitch a ride on plants or packages. Moisture-damaged areas, poorly sealed doors, and other structural weak spots make it even easier for these persistent pests to get in.

How to Prevent Ants in the House

Preventing ants starts with making your home less inviting to these persistent pests. Though they may seem small and harmless, ants can quickly turn into a significant nuisance if ignored. By following a few simple strategies, you can create a space that naturally keeps ant invasions at bay.

  • Seal Entry Points: Use caulk to close cracks in foundations and around windows and doors. Repair any gaps where utilities enter the house.

  • Eliminate Food Sources: Clean up spills and crumbs immediately. Store food in sealed containers and empty trash regularly.

  • Reduce Moisture: Repair water leaks and address areas of standing water. Ensure proper drainage around your home's foundation.

  • Maintain Your Yard: Keep plants and tree branches trimmed away from your house. Store firewood and debris far from the foundation.

  • Regular Cleaning: Vacuum frequently, especially in eating areas. Wipe down counters and appliances to remove food residue.

By consistently following these steps, you can significantly reduce the likelihood of ant infestations in your home.

A persistent ant infestation can quickly worsen, causing damage to your home and becoming harder to control.
