Ants in the house usually mean a nearby colony has found access to food, moisture, or shelter inside your home. The most effective way to get rid of ants is to eliminate attractants, place ant bait near active trails, and seal the small gaps ants use to enter. While sprays may kill visible ants quickly, bait works better long-term because worker ants carry it back to the nest.
Whether you're dealing with tiny ants in the kitchen, black ants near windows, or recurring ant trails along baseboards, early treatment helps prevent a small problem from turning into a larger ant infestation.
Why are ants getting into your house?
Ants come inside looking for food, water, and shelter. They can squeeze through openings as small as 1/16 of an inch, making gaps around windows, doors, plumbing lines, and house foundations all potential entry points. Once a scout finds a resource, it leaves a chemical trail that guides the rest of the colony. Knowing what's drawing them in makes it easier to address the source.
Common indoor ant attractants include:
- Food crumbs, spills, and unsecured pantry items
- Standing water from leaky pipes, drains, or condensation
- Pet food left in bowls overnight
- Warmth and moisture in bathrooms, basements, and crawl spaces
What kills ants?
Understanding what kills ants helps you choose the right method. Contact sprays kill on sight but don't reach the colony. Ant bait is generally the more effective solution because foraging workers carry it back to the nest, where it works through the broader population over time. For most indoor ant problems, bait is the recommended starting point for ant control.
Potential ant control methods:
- Ant bait stations: Place near active trails and entry points; give ants time to carry bait back to the colony rather than disturbing the trail.
- Granular or gel bait: Works well in kitchens, under appliances, and in pantry areas.
- Sprays and dusts: Effective for cracks, baseboards, and direct entry point treatment.
Keep in mind that each ant control method works differently. Contact sprays kill visible ants immediately, but they usually do not eliminate the colony. Ant bait is often more effective because worker ants carry the bait back to the nest, allowing it to spread through the colony over time.
For persistent, hard-to-locate, or large indoor ant infestations, or ants inside walls, professional ant control may be necessary to locate hidden nests and apply targeted treatment.
How to get rid of ants in the kitchen
The kitchen is the most common location for indoor ant activity. Getting rid of ants in the kitchen starts with removing the food and moisture that bring them in, then treating active trails with bait.
Kitchen ant control steps:
- Store food in sealed, airtight containers
- Clean crumbs, grease, and spills daily, including under and behind appliances
- Empty and wash pet food bowls after each meal
- Fix leaky pipes or dripping faucets under the sink
- Place bait stations along baseboards, under the sink, and behind appliances
How to get rid of ants naturally
For those looking to get rid of ants naturally, several home remedies for ants can help limit activity when used consistently.
Natural methods that can help deter ants:
- White vinegar: Wipe along active trails to disrupt the pheromone path.
- Diatomaceous earth: Sprinkle the powder in areas where you’ve located ants.
- Peppermint or tea tree oil: Apply around entry points to deter trailing.
- Dish soap and water: A simple contact spray for visible ants on surfaces.
“One great option is diatomaceous earth. This fine powder, made from fossilized algae, is completely non-toxic to humans and pets but deadly to many insects including ants,” said Isaac Rockwell, Aptive's in-house entomologist. “It works by damaging the exoskeletons of insects, causing them to dehydrate and die. Just sprinkle it in areas where pests are seen or likely to be present. Food-grade diatomaceous earth is the safest option for home use.”
Keep in mind that while natural remedies for ants may help reduce activity temporarily, they typically work best for smaller problems or alongside bait-based ant control. Severe ant infestations often require a more comprehensive treatment approach.

Dealing with carpenter ants specifically? Unlike sugar ants, carpenter ants tunnel through wood and require targeted treatment as they are difficult to locate and can cause structural damage.
How to keep ants away long-term
Keeping ants away requires addressing the structural and environmental conditions that invite them back. Combining indoor and outdoor steps gives the most consistent results.
Long-term steps to keep ants away:
- Seal cracks and gaps around windows, door frames, and plumbing entry points with caulk
- Keep gutters clean and redirect moisture away from the foundation
- Trim trees and shrubs that touch the exterior of your home
- Store firewood elevated and away from the house
- Treat the yard perimeter and locate active nests near the foundation to address how to get rid of ants outside before they make their way in

Ants in the house FAQs
Q: How to get rid of ants in the house quickly?
The fastest approach is to vacuum up visible ants immediately, then wipe active trails with a vinegar solution to disrupt the pheromone path. Follow up by placing ant bait stations near areas of activity. Bait takes a few days to work through the colony, but combining immediate cleanup with bait gives you both a fast reduction in visible ants and longer results.
Q: What scent keeps ants away?
Strong smells like peppermint oil, tea tree oil, citrus, and vinegar may help deter ants by disrupting their pheromone trails. While these scents can reduce activity temporarily, they typically work best alongside baiting, sanitation, and sealing entry points.
Q: Why are there ants in my house?
Ants come inside searching for food, water, and shelter. Common triggers include food crumbs or spills left on surfaces, leaky pipes or standing water, and pet food left out overnight. They can enter through tiny cracks around windows, doors, and plumbing lines. Once one ant finds a resource and leaves a pheromone trail, others follow quickly. Removing attractants and sealing entry points are the most effective first steps.
Q: Do ants go away on their own?
In most cases, ants do not go away on their own. Once a colony has identified a food or water source inside your home, it will continue sending workers until that source is removed. Small trails can grow into a larger ant infestation over time if left unaddressed. Eliminating attractants and treating active trails promptly gives you the best chance of resolving the problem before it becomes harder to manage.
