Summer in San Diego brings sunshine, beach days, and unfortunately, summer pests—particularly ants. As temperatures rise, ant activity surges, and your home becomes a prime target for these persistent invaders. If you’re noticing trails of ants along windowsills, countertops, or baseboards, you’re not alone. Fortunately, there are effective ways to combat ant infestations and keep your home protected all summer long.
Protecting Your Home From Ant Infestations
Why Ants Invade During Summer
Ants are warm-weather pests. When temperatures climb and food or moisture sources outside become scarce, ants begin to explore homes in search of shelter, food, and water. San Diego’s Mediterranean climate offers ideal conditions for ant colonies to thrive, especially in residential neighborhoods with access to crumbs, leaks, and unsealed entry points.
Common ant species found in Southern California include Argentine ants, odorous house ants, and pavement ants. Of these, Argentine ants are particularly aggressive invaders. They form massive colonies and send out multiple queens, making them incredibly difficult to eliminate without professional ant control.
How to Prevent Ants From Entering Your Home
Prevention is key when it comes to keeping ants at bay. Here are some proven strategies to reduce your risk of an infestation:
1. Seal Entry Points
Ants are tiny, and it doesn’t take much for them to slip through cracks and crevices. Inspect your home’s foundation, windows, doors, and plumbing for potential entryways. Use caulk to seal gaps and weather stripping to close off under-door gaps.
2. Eliminate Food Sources
Keep food tightly sealed in containers, clean up crumbs and spills promptly, and don’t leave pet food out overnight. Ants are particularly drawn to sugary items, so be extra diligent in the kitchen and pantry.
3. Control Moisture
Leaky pipes, dripping faucets, and damp areas like under the sink can attract ants. Fix plumbing issues quickly and use a dehumidifier in particularly humid areas of the house.
4. Maintain Outdoor Landscaping
Keep trees and shrubs trimmed away from your home’s exterior, as ants often use branches as a bridge into your house. Remove dead wood, leaf litter, and any organic debris that can serve as nesting material.
5. Use Ant Baits (With Caution)
Over-the-counter ant baits can sometimes help with small infestations, but incorrect placement or usage can make the problem worse by splitting colonies. For more serious or recurring issues, professional pest control services are highly recommended.
When to Call the Pros
