Why Are There Ants in My Kitchen? (And How to Actually Get Rid of Them)

Every spring, the number one pest complaint across northeast Georgia is the same: ants in the kitchen. They seem to appear overnight, a few on the counter, then a trail to the cabinet, then suddenly they’re everywhere. Understanding why they’re there and how ant colonies actually work is the key to getting rid of them effectively.

Why Are They in Your Kitchen Right Now?

Ants operate on a scout-and-recruit system. A small number of forager ants leave the colony in search of food and water. When one finds a source, your counter, your pet’s bowl, the sticky ring under the honey jar, it returns to the colony leaving a chemical pheromone trail. Other ants follow that trail to the food source, reinforcing it as they return. What starts as one ant becomes a line of hundreds within hours.

Spring triggers this foraging behavior because:

• Warming temperatures increase ant activity after the winter slowdown
• Spring rains can flood underground nests and force ants to relocate and find new food
• Colony populations that built up over winter are at their largest and need the most food

Identifying What You’re Dealing With

Not all ants are the same, and treatment differs by species.

Argentine Ants, tiny (⅛ inch), light brown, traveling in very wide trails. The most common kitchen ant in Georgia. They form massive “supercolonies” that can span entire neighborhoods, with multiple queens. This is important because killing the workers you see has minimal impact on the colony.

Odorous House Ants, slightly larger, dark brown/black, and when crushed they emit a smell like rotten coconut. Very common in kitchens. Also multi-queen colonies.

Pavement Ants, small, dark, often entering from the foundation. Will trail to kitchens and bathrooms.

Carpenter Ants, much larger (¼ to ½ inch), black or black-and-red. Finding large ants in your kitchen is a different problem than small ones, carpenter ants nest in wood, and their presence inside often indicates a moisture problem in structural wood. This warrants a professional inspection.

Fire Ants, you won’t usually find these inside, but if you have large outdoor mounds near your home, they’re worth addressing before they become an inside problem.

What Not to Do

Don’t spray the trail with over-the-counter spray. This is the most common mistake. Killing the foragers you can see does not kill the colony, it just causes the colony to fracture, create new trails, and potentially spread the problem to other areas of the house. The pheromone trail may also confuse surviving ants and cause erratic foraging behavior.

Don’t use repellent barrier sprays near active bait. Repellents will prevent ants from reaching the bait, defeating the purpose.

What Actually Works: Bait

For small ant species (Argentine ants, odorous house ants), bait is the gold standard. Slow-acting bait is carried back to the colony by worker ants and fed to the queen and larvae. Because it’s slow-acting, many workers consume it and carry it home before dying. This targets the queen, the source of the infestation, not just the foragers you can see.

Bait placement tips:

• Place small amounts directly on the ant trail, not beside it
• Use sweet bait (sugar-based) in spring; ants switch to protein preferences mid-summer
• Don’t wipe down the trail with cleaners before baiting, the pheromone trail leads ants to the bait
• Be patient, it can take 48-72 hours to see results, and 1-2 weeks for full effect
• Resist the urge to spray if you still see ants while the bait is working

Preventing Re-Entry

Once the immediate infestation is addressed, take these steps to prevent recurrence:

• Store all food in sealed containers, including pet food
• Fix any leaky faucets or pipes under sinks
• Caulk gaps around plumbing penetrations under the sink
• Keep counters clean of crumbs and spills, especially sweet residue
• Pull pet food bowls up off the floor when not in use
• Apply a perimeter treatment around the exterior foundation

When to Call a Professional

Call us if:

• You’ve been battling ants for more than 2-3 weeks with no improvement
• You’re seeing large (carpenter ant-sized) ants inside
• You’re finding multiple trails in multiple rooms
• You’ve used bait but the infestation persists (the bait may not be the right formulation for your ant species, or the colony may be too large for DIY bait alone)

Kilz Pest Control provides targeted ant treatment for homes across northeast Georgia. We identify the species, find the entry points, and apply professional-grade bait and barrier treatments to resolve the infestation.
