How to Get Rid of Ants in the Kitchen and Keep Them Out

The best way to get rid of ants in the kitchen is to clear the trail with soapy water, follow it to the crack or pipe where ants enter and seal it, move every sweet or greasy food into containers with tight lids, and set a bait station on the trail near the entry. Clean behind and under appliances, where spills feed ants out of sight.

Why Ants Suddenly Appear in the Kitchen

Kitchen ants are foragers from a colony that is usually outside or in a wall. When a scout finds sugar, grease, crumbs or water, it lays a scent trail and others follow, which is why a few ants become a line overnight. Warm weather, rain and dry spells all push colonies to forage harder, so invasions often start suddenly.

UC IPM's ant pest notes list what household ants feed on indoors: sugar, syrup, honey, fruit juice, fats and meat. A kitchen offers all of them, along with water at the sink and dishwasher.

The fix is to take away what the kitchen offers and close the route in. For the whole-house plan and the colony outside, see our guide on how to get rid of ants.

How to Clear Ants From the Kitchen

1. Wipe the trail. Sponge it with soapy water, which kills the ants it soaks and erases the scent trail.
2. Follow it back. Trace the line away from the food to where it enters: a gap at the backsplash, a window frame, the hole where pipes come through under the sink.
3. Seal the entry. Caulk the gap, or press petroleum jelly into it until you can caulk.
4. Empty the target. Find what they were after, often a sticky jar, a torn bag or a spill, and clean it up.
5. Bait the trail. Put a bait station on the trail near the entry and leave it alone while ants feed.
6. Wait it out. Keep the area clean and do not spray near the bait; UC IPM says it can take 5 to 10 days to see fewer ants.

Cabinet by Cabinet: Where Kitchen Ants Feed

• Pantry and dry goods: move sugar, cereal, flour, crackers and pet food from bags and boxes into containers with tight lids; UC IPM advises closed containers washed clean on the outside.
• Sweets shelf: honey, syrup and jam jars collect drips on the outside and under the lid; wipe them and stand them on a tray.
• Under the sink: check for leaks and damp wood, wipe the trash cabinet and seal gaps where pipes enter the wall.
• Trash and recycling: empty food waste daily, change liners often, and rinse soda cans and bottles before they go in the bin.
• Fruit bowl: overripe fruit and juice draw ants; refrigerate ripe fruit or wipe the bowl daily.

Appliances, Floors and Kitchen Walls

Ants often feed where you cannot see. Pull out the stove and refrigerator once and clean the floor and sides, wipe the gap between the stove and counter, and clean food from the dishwasher door seal and the filter. Check the toaster and microwave for crumbs underneath.

For ants coming out of kitchen walls, behind outlets or at the backsplash, seal what you can reach and put bait stations or a small amount of gel bait at those openings, so foragers carry bait back into the wall. Do not spray into outlets or wall cavities; it kills only the ants it reaches.

Natural Kitchen Remedies: What Works

Does Dawn dish soap really kill ants? Soapy water kills ants it soaks and wipes away their trail, which makes it the best natural first step on counters. UC IPM notes some soap products such as window cleaner also kill ants on contact without leaving residues, which matters around food.

Vinegar cleans a trail like any cleaner, but there is no reliable evidence its smell keeps ants away once dry, and no single smell ants “hate” has proven to keep them out of a kitchen. Plant-oil sprays kill on contact but, per UC IPM, have limited residual activity. For homemade baits and other natural methods, the getting rid of ants section links each option.

How to Keep Ants Out of the Kitchen

A kitchen stays ant-free when there is nothing loose to find. Wipe counters and the floor along cabinets each night, keep sweets and pet food sealed, fix leaks under the sink, and take out food waste daily. Caulk gaps at the backsplash, around windows and where pipes enter, before the season ants usually arrive.

If trails keep starting from the same outside wall, set bait stations outside along that wall, where UC IPM recommends most baiting, so the colony is dealt with before ants reach the kitchen. Keep mulch and shrubs a few inches back from that wall too, since plants touching the house give ants a sheltered route to the windows.

Common Questions About Ants in the Kitchen

Key Takeaways

Kitchen ants come for sugar, grease and water, and they follow a trail from a gap you can find. Wipe the trail with soapy water, trace it back and seal the entry, move sweets and pet food into sealed containers, and bait the trail near where ants come in.

Clean behind appliances and under the sink, where spills feed ants out of sight, and keep insecticide sprays off counters and food areas. If ants keep coming after a few weeks, bait outside along the wall they come through.

Tonight, empty the cabinet the ants are visiting, wipe it out and seal what they were eating.
