How to Get Rid of Ants in Your House: 12 Proven Methods That Work
Finding ants inside your home can be frustrating. At first, you may notice only a few ants on the kitchen counter or near the sink. But those few ants are usually just the beginning of a much larger colony searching for food and water.
Ants are among the most common household pests in the United States. Once they establish a trail into your home, they can quickly spread throughout kitchens, bathrooms, pantries, and even wall voids.
The good news is that most ant infestations can be controlled by removing food sources, using the right bait products, sealing entry points, and maintaining a clean home.
In this guide, you'll learn why ants invade homes, the 12 most effective ways to get rid of them, how to prevent future infestations, and when it's time to call a professional pest control company.
Even a few ants inside your home can indicate a much larger colony nearby.
Quick Answer
If you're wondering how to get rid of ants in your house, follow these proven steps:
- Identify where the ants are coming from.
- Clean up food and sugary spills immediately.
- Use ant bait stations instead of spraying individual ants.
- Seal cracks and entry points.
- Remove standing water and excess moisture.
- Trim plants touching your home.
- Call a pest control professional for severe infestations.
Following these steps will eliminate most common household ant problems and help prevent them from returning.
Why Are Ants Coming Into Your House?
Ants enter homes for one simple reason—they're searching for food, water, and shelter.
Scout ants explore your home looking for resources. Once they find food, they leave a chemical trail (called a pheromone trail) that guides the rest of the colony directly to the source.
Common things that attract ants include:
- Sugary drinks and food spills.
- Pet food left out overnight.
- Dirty dishes in the sink.
- Open food containers.
- Standing water under sinks.
- Garbage cans without tight-fitting lids.
- Crumbs on kitchen counters and floors.
Removing these food and water sources is often the first and most important step toward eliminating an infestation.
Method 1: Find the Ant Trail
Before using any treatment, spend a few minutes watching where the ants are traveling.
Look for:
- Cracks around windows and doors.
- Gaps near plumbing pipes.
- Openings around electrical outlets.
- Foundation cracks.
- Exterior walls and landscaping.
Finding the trail helps you determine where to place bait stations and where to seal entry points later.
Method 2: Eliminate Food Sources
Even the best ant bait won't solve the problem if ants continue finding food inside your home.
Make these habits part of your daily routine:
- Wipe kitchen counters after every meal.
- Sweep and vacuum regularly.
- Store dry foods in airtight containers.
- Take out the trash frequently.
- Clean up sugary spills immediately.
- Avoid leaving pet food out overnight.
Reducing available food forces ants to rely on bait, making treatments much more effective.
Ant bait stations work better than spraying visible ants because they target the entire colony.
Method 3: Use Ant Bait Stations
One of the most effective ways to eliminate an ant infestation is by using ant bait stations instead of insecticide sprays.
Worker ants carry the bait back to the colony, where it is shared with other ants—including the queen. This approach targets the source of the infestation rather than just the ants you can see.
For the best results:
- Place bait stations directly along active ant trails.
- Do not spray insecticide near the bait.
- Allow the ants to continue feeding for several days.
- Replace bait as needed until ant activity stops.
Although you may see more ants at first, this is a normal sign that the bait is attracting workers back to the colony.
Method 4: Seal Entry Points
Once you've identified where ants are entering your home, seal those openings to prevent new ants from getting inside.
Inspect common entry points such as:
- Cracks around windows and doors.
- Gaps where utility pipes enter the house.
- Openings around electrical cables.
- Foundation cracks.
- Damaged weather stripping.
Use silicone caulk or another appropriate sealant to close small openings. Blocking entry points is one of the best long-term solutions for preventing future infestations.
Method 5: Remove Standing Water
Like all living creatures, ants need water to survive. Moist areas around your home can attract ants even if food is limited.
Check for:
- Leaking faucets.
- Dripping pipes.
- Wet sponges left on countertops.
- Standing water under sinks.
- Pet water bowls left overnight.
Fixing plumbing leaks and keeping surfaces dry makes your home far less attractive to ant colonies.
Sealing cracks around your home's exterior helps stop ants before they enter.
Method 6: Try Natural Ant Repellents
If you prefer avoiding chemical pesticides, several natural remedies may help discourage ants from entering your home.
Popular natural options include:
- White vinegar mixed with water.
- Lemon juice.
- Peppermint essential oil.
- Cinnamon.
- Diatomaceous earth (food grade).
These remedies work best for minor infestations and as part of an overall prevention strategy. They may not eliminate a large colony on their own.
Method 7: Trim Trees and Shrubs
Ants often use tree branches, shrubs, and other vegetation as bridges to reach your home.
Keep plants trimmed so they don't touch:
- Your roof.
- Exterior walls.
- Windows.
- Gutters.
Removing these natural pathways can significantly reduce the number of ants entering your house.
Method 8: Keep Outdoor Trash Areas Clean
Garbage cans are a major food source for ants. If ants establish colonies around outdoor trash bins, they're much more likely to find their way inside your home.
To reduce the risk:
- Use trash cans with tight-fitting lids.
- Clean garbage bins regularly.
- Rinse food containers before disposal.
- Keep outdoor bins away from exterior doors whenever possible.

When Should You Call a Pest Control Professional?
While many ant problems can be handled with DIY methods, some infestations require professional treatment.
Consider calling a pest control company if:
- Ants keep returning after treatment.
- You discover multiple colonies around your property.
- The infestation has spread into walls or ceilings.
- You suspect carpenter ants damaging wood.
- DIY treatments have failed after several weeks.
Professional pest control technicians can identify the ant species, locate hidden nests, and apply targeted treatments that eliminate the colony more effectively.
Method 9: Remove Outdoor Ant Nests
If you locate an ant nest near your home's foundation, driveway, or garden, treating the nest directly can greatly reduce the number of ants entering your house.
Depending on the ant species, you can use:
- Outdoor ant bait granules.
- Boiling water for small visible nests.
- Approved outdoor insecticides.
- Professional pest control treatments for large colonies.
Always follow the manufacturer's instructions when using outdoor pest control products.
Method 10: Store Food Properly
Even a small amount of exposed food can attract hundreds of ants.
To reduce the risk:
- Store cereal, sugar, flour, and snacks in airtight containers.
- Keep fruit in the refrigerator during warm weather.
- Wipe food containers before placing them back in cabinets.
- Clean crumbs from kitchen drawers and pantry shelves.
Proper food storage removes one of the biggest reasons ants enter your home.
Method 11: Inspect Your Home Regularly
Routine inspections help you spot ant activity before it becomes a serious infestation.
Every few weeks, inspect:
- Kitchen cabinets.
- Bathroom sinks.
- Window frames.
- Garage corners.
- Basement walls.
- Exterior foundation.
Early detection makes treatment faster, easier, and less expensive.
Method 12: Schedule Professional Pest Control
If ants continue returning despite your best efforts, professional pest control may be the most effective solution.
Licensed technicians can:
- Identify the ant species.
- Locate hidden nests.
- Apply targeted treatments.
- Recommend long-term prevention strategies.
Keeping your home clean and sealing entry points helps prevent future ant infestations.
How to Prevent Ants from Coming Back
- Keep kitchen surfaces clean every day.
- Repair leaking pipes and faucets.
- Seal cracks around doors and windows.
- Store food in airtight containers.
- Empty trash cans regularly.
- Trim plants that touch your home.
- Inspect your home for new ant trails.
Consistent prevention is the best way to avoid another infestation.
Frequently Asked Questions
Why do ants keep coming back?
Ants usually return because food sources remain available or the original colony has not been eliminated. Sealing entry points and using bait stations together often produces the best results.
What kills ants the fastest?
Sprays kill the ants you see immediately, but bait stations are generally more effective because worker ants carry the bait back to the colony, eventually eliminating the queen.
Are natural remedies effective?
Natural remedies such as vinegar, peppermint oil, and cinnamon can discourage ants, but they are usually less effective than bait products for large infestations.
When should I call a pest control company?
If ants continue returning after several weeks of treatment, or if you suspect carpenter ants or multiple colonies, professional pest control is recommended.
Can ants damage my house?
Most household ants are simply a nuisance, but carpenter ants can tunnel through damp or damaged wood, potentially causing structural damage if left untreated.
Conclusion
Getting rid of ants requires more than simply spraying the insects you can see. The most effective approach combines proper sanitation, ant bait stations, sealing entry points, and eliminating outdoor nesting areas.
By acting quickly and following the prevention tips in this guide, you can eliminate most household ant infestations and greatly reduce the chances of them returning.
If the problem persists despite repeated treatment, don't hesitate to contact a licensed pest control professional for a complete inspection and customized treatment plan.
