Ants can invade your kitchen in search of food, quickly becoming a frustrating and unsanitary pest. These tiny pests contaminate food, trail across countertops, and can be difficult to eliminate once they establish scent trails leading back to their colony. If you’re dealing with an ant infestation, prompt action is necessary to remove ants and safeguard your home from future intrusions.
While do-it-yourself (DIY) methods can help mitigate ant problems, severe or persistent infestations—especially those involving carpenter ants—are best left to a licensed pest control expert. They can swiftly and effectively resolve the ant problem, ensuring these invaders stay out of your home for good.
Why Are There Ants in My Kitchen?
Food sources bring ants into your kitchen. There are thousands of species of ants, but the most common types you’ll find in your kitchen are pharaoh ants, pavement ants, odorous house ants, thief ants, and Argentine ants. That’s because these ant species are attracted to the sugar in food, especially noticeably sweet foods like honey and syrup. They also need water and can usually find it in and around a kitchen sink.
Importantly, ants leave behind scent trails that allow them to follow each other. This is how one or two ants can become a full infestation. The trailblazers leave a path of scent chemicals called pheromones, and other ants know to follow these pheromones to find food or water. That’s why you’ll often see ants marching in lines. Understanding this behavior is key to both finding where the ants are coming from and wiping them out.
Types of Ants in a Kitchen Infestation
Ant infestations in the kitchen can be frustrating, as these pests are drawn to food, moisture, and shelter. While all ants follow scent trails and work together to establish colonies, different species have unique behaviors that require specific control methods. Identifying the type of ant in your kitchen is essential for effective removal and prevention.
Pharaoh Ants: The Persistent Invaders
Most common in: Southern U.S., especially Florida, Texas, and the Gulf Coast
Pharaoh ants are small, yellowish ants that thrive in warm, humid environments like kitchens. They are especially problematic because they establish multiple nests, making them difficult to eliminate with standard DIY methods. They are highly attracted to sugary foods but will also feed on proteins, making any exposed food in your kitchen a target.
Pro Tip
- Patricia Zungoli, an entomologist at Clemson University, emphasizes the importance of eliminating indoor hiding spots: “The more hiding places, the greater the number of pests your home can support.” Reducing clutter in your kitchen—especially around countertops, pantries, and baseboards—removes the shelter that pavement ants seek once they’ve migrated indoors.
Pavement Ants: The Outdoor Migrants
Most common in: Northeastern, Midwestern, and Pacific Northwest states
Pavement ants typically build nests under sidewalks, driveways, and home foundations. However, they venture indoors in search of food, especially during colder months or periods of heavy rain. They are attracted to a variety of foods, including sweets, grease, and crumbs left on countertops or floors.
Pro Tip
- To help keep pavement ants from finding their way inside, This Old House Magazine recommends trimming trees and shrubs 4 to 6 inches away from your house and foundation so ants won’t have an easy pathway to crawl in.
Odorous House Ants: The Scented Foragers
Most common in: Across the U.S., but especially in the Midwest and East Coast
Odorous house ants are known for the strong, rotten coconut-like smell they emit when crushed. These ants are drawn to sweet substances like fruit juice, honey, and syrup. They often nest indoors in wall voids or under floors, making them particularly difficult to eliminate without targeted baiting strategies.
Pro Tip
- Because odorous house ants hide out in walls and floors, visible foragers represent only a fraction of the colony. According to This Old House Magazine, you need to employ a variety of controls: set up bait traps so the ants carry the pesticide back to the nest, and since ants are attracted to moisture as well as food, use a dehumidifier in damp spaces and eliminate standing water near your home.
Thief Ants: The Sneaky Scavengers
Most common in: Southern and Midwestern states
Thief ants are tiny and often mistaken for pharaoh ants, but they pose their own challenges. They get their name because they steal food from other ant colonies, but they also invade kitchens to feed on greasy and protein-rich foods, such as peanut butter and meat. Their small size allows them to slip into sealed food containers, contaminating stored goods.
Pro Tip
- While odorous house ants are often referred to as sugar ants, they will actually go for any food and water they can find—not just sweet substances. As noted in This Old House Magazine, “while they do love sweets (and are often referred to as sugar ants), they will go for any food and water.”
Argentine Ants: The Rapid Spreaders
Most common in: Southeastern and Western U.S., especially California and Georgia
Argentine ants are highly aggressive and can quickly take over a kitchen. They form massive colonies with multiple queens, allowing them to reproduce and expand rapidly. These ants are drawn to sweets and moisture, often making their way into homes through tiny cracks in search of food and water.
Pro Tip
- Tanya Drlik, a pest-management specialist at the nonprofit Bio-Integral Resource Center in Berkeley, California, notes that Argentine ants can even build nests inside your home: “The ants don’t like wet soil. They’ll actually make little bridges with their bodies” to escape when disturbed. Drlik recommends taking houseplants outside and submerging the pots in buckets of water to flush out any hidden nests in the soil.
Carpenter Ant Infestations
Most common in: Northern U.S., Pacific Northwest, and parts of the Midwest
A less common ant species to find in your kitchen is carpenter ants. While most ants are nuisance insects, carpenter ants actually damage your house. These big, blackish-red bugs burrow through wood and can cause structural damage to your home quickly. If you see piles of sawdust or wood shavings, they may be digging nests near an exposed beam. We recommend you contact the professionals immediately.
How to Get Rid of Ants in the Kitchen
According to the University of Kentucky Entomology Department, the biggest mistake that homeowners make when trying to get rid of ants is simply eliminating the ones they see with kill-on-contact spray. Here, we’ll break down four steps for getting rid of the whole colony of ants that are infesting your kitchen and then keeping them away.
Find and kill the ant colony
Follow the ants’ scent trails to track their path and locate the nest, which may be hidden in cabinets, walls, or floors. Simply killing visible ants won’t solve the problem, as more will replace them. If you find the nest, apply a non-repellent insecticide to avoid scattering the colony. If the nest is inaccessible, use bait traps or gels to lure ants into carrying poison back to their colony. Avoid spraying ants with on-contact killers while using bait. If one bait isn’t effective, try another.
Seal ants out
While you’re looking for the colony, make careful notes of the ants’ entry and exit points to your kitchen. You don’t want to seal them before the bait has a chance to work, but once you’re confident that the nest has been mostly eliminated, you can start ant-proofing your kitchen. Seal any cracks or crevices with caulk or joint compound. You can also put boric acid in crevices.
Kill remaining ants
Use a kill-on-contact spray carefully in your kitchen, avoiding food and washing any contaminated surfaces. If you prefer natural solutions, wipe away stragglers with a mix of water and dish soap or disrupt scent trails with vinegar, lemon juice, or soapy water. Don’t clean too soon if using baits, as it can interfere with their effectiveness.
Prevent ants from coming back
To prevent ants from returning, store all food—including pet food—in airtight containers and keep surfaces clean. Wipe up spills, wash dishes promptly, and keep the sink dry. Sweep, mop, and vacuum regularly to remove crumbs, and take out the trash often using sealed, durable bags.
What If I’ve Still Got Ants?
Some infestations are especially stubborn because ants can hide in tiny crevices, inside walls, or under floors, making it difficult to eliminate the entire colony. Even after using bait and sealing entry points, some ants may persist due to secondary nests or undetected food sources. In some cases, DIY treatments only target the visible ants while leaving the queen and the main colony intact, allowing the infestation to continue.
If you’ve tried multiple solutions and ants keep returning, it may be time to call a professional pest control provider. Experts have access to specialized insecticides, advanced baiting techniques, and technology like thermal imaging or moisture detection to locate hidden nests. They can also identify the specific ant species and customize a treatment plan such as fumigation to eliminate them effectively. Additionally, pest control services offer long-term prevention strategies to ensure ants don’t return, such as exterior treatments, barrier applications, and expert advice on keeping your kitchen pest-free.
