Dealing with an ant infestation in your kitchen can be incredibly frustrating. Ants can contaminate your food, cause structural damage, and even pose health risks in some cases. Getting rid of ants for good requires patience and persistence, but it can be done through a combination of preventative measures, natural remedies, and chemical treatments if necessary. This comprehensive guide will provide tips and solutions to help you kick ants out of your kitchen once and for all.

Understanding Ant Behavior

To get rid of ants, it’s important to first understand what attracts them and how they behave.

Why Ants Are Attracted to Your Kitchen

Ants are attracted to food sources and moisture. Kitchens provide both of these elements, making them a prime target for ant infestations. Common food sources that attract ants include:

Spilled crumbs, juices, grease etc.
Pet food bowls
Open food containers and bags
Fruits and vegetables
Garbage cans and recycling bins
Leaky pipes, sinks, and appliances

Ants use pheromone trails to mark paths from their nest to food sources. Once they discover a food source in your kitchen, they can recruit more ants to follow the trail. This allows large numbers of ants to rapidly converge on your kitchen.

How Ants Get Into Your Home

There are a few common entry points ants use to get into kitchens:

Cracks and crevices – Ants can squeeze through extremely small spaces. Any cracks in walls, windows, door frames, etc provide access.
Under doors – A gap of less than 1/16 of an inch under a door is all ants need to get inside.
Plumbing penetrations – Ants will follow pipes and wiring into walls from the outside.
Vents – Kitchen vents connected to the outdoors allow ants to move in and out.

Ant Nest Location

Identifying where ants are nesting can help you find and eliminate access points. Ant nests are often located:

Outdoors – in the ground, under objects, and inside woodpiles. Outdoor nests may have trails leading inside.
In wall voids and hollow spaces.
Under appliances, cabinets, or sinks that leak moisture.
Inside panels of doors and windows.

Preventing Ants in Your Kitchen

Taking preventative measures is the best line of defense against future ant infestations.

Seal Possible Entry Points

Seal any cracks, crevices, and openings that could allow ants to enter your kitchen. This includes:

Caulking cracks in walls, floors, and ceilings
Weatherstripping under doors and windows
Sealing openings around pipes and wires
Repairing any water leaks
Screening vents

Remove Food Sources

Eliminate access to sugary, greasy, and starchy foods that attract ants.

Keep counters, floors, and sinks clear of spills and crumbs
Store food in airtight containers
Empty garbage frequently
Clean pet food bowls after each meal
Rinse recyclables before storing them
Fix any leaky appliances, pipes, and faucets

Store Attractants in Closed Containers

Keep food items that appeal to ants in tightly sealed containers, rather than leaving them exposed on counters or in cabinets. This includes things like:

Honey and syrup
Fruits and vegetables
Sugary baked goods
Greasy, crumbly, or sticky foods

Remove Indoor Plants

Houseplants provide moisture that ants use for hydration. Eliminating indoor plants in your kitchen cuts off this water source.

Manage Waste Properly

Follow good waste management practices:

Take garbage out frequently
Use lined containers with tight fitting lids
Rinse recyclables to avoid residue
Keep outdoor bins away from the house

Reduce Moisture

Fix any leaky appliances, pipes, and faucets. Thoroughly dry sinks after washing dishes. Moisture allows ants to survive and breed indoors.

How to Get Rid of Ants – Natural Remedies

If you already have an ant problem, there are several natural remedies that can help eliminate ants without using harsh chemicals.

Vinegar

White vinegar kills and repels ants. Mix equal parts vinegar and water in a spray bottle. Spray it directly on ants to kill them, and apply liberally along baseboards, windowsills, door frames, and any other areas ants frequent.

Vinegar destroys the scent trails ants use to navigate and cuts off their routes into your home. The strong odor also acts as a repellent. Reapply the vinegar solution multiple times per week until ant activity stops completely.

Diatomaceous Earth

Diatomaceous earth (DE) is a powder made from crushed fossils of aquatic organisms. The sharp edges scratch the waxy coating on ants’ exoskeletons, causing them to dehydrate and die. DE is non-toxic to humans and pets.

Apply a fine layer of diatomaceous earth along baseboards, under appliances, around pipe openings, and other places where ants enter. It will kill ants that cross over it. Reapply after cleaning or if rain gets the powder wet. Wear a dust mask when working with DE to avoid inhaling the powder.

Lemon Juice/Peels

Lemons contain citric acid and strong scents that deter ants. Squeeze lemon juice directly onto ants or saturate cotton balls and place them along ant trails. You can also rub lemon peel directly on counter edges, windowsills, and door frames. The smell with mask scent trails and repel ants. Reapply lemon juice or peels multiple times per week.

Pepper and Salt

Layer black pepper, cayenne pepper, salt, or a combination around ant nests or entry points. The coarse textures annoy ants and disrupt pheromone trails. The ingredients alsoabsorb moisture, making the areas less hospitable for ants. Reapply pepper and salt after sweeping or cleaning. Do not use this method directly on plants, as it will damage foliage.

Chalk and Baby Powder

Chalk and baby powder contain fine particles that stick to ants’ bodies, drying them out. Draw chalk lines where ants are entering your home, or pour baby powder across their trails. Both ingredients also block pheromone trails. Reapply frequently on dry days since rain and moisture erase the effectiveness.

Essential Oils

Many essential oils like peppermint, tea tree, lavender, eucalyptus, and citrus naturally deter ants with their strong scents. Mix 5-10 drops of your chosen oil in a spray bottle filled with water. Mist the oil solution in problem areas and directly on ants. The oils disrupt the scent communication ants rely on. Reapply daily as the smells fade.

Boiling Water

Pour boiling water directly onto ant nests to effectively eliminate them. This method works especially well for nests located in houseplants, yards, driveways, sidewalk cracks, and other outdoor areas around your home’s perimeter. The hot water essentially fries the ants and destroys the nest.

Ant Killers – Chemical Treatments

For serious ant infestations, you may need to use a chemical treatment in combination with natural remedies.

Boric Acid

Boric acid is one of the most effective and long-lasting chemical treatments for ant infestations. The powder is made from boron and kills ants slowly over a 1-2 week period. When ants ingest it, the boric acid erodes their stomachs and causes a fatal gradual poisoning throughout the colony. It also damages their exoskeletons on contact.

Boric acid can be used indoors and outdoors. Sprinkle it lightly in concealed areas along baseboards, inside cabinets, under appliances, behind kitchen pipes, and in other out-of-sight places where you see ants traveling. Since it is odorless and non-staining, it will not negatively impact your home’s appearance. Reapply boric acid if ant activity resumes.

Keep boric acid inaccessible to children and pets, as it can be harmful if ingested in large amounts. Avoid skin contact when applying. Wear gloves and wash hands after use.

Ant Baits and Traps

Ant baits combine food attractants and boric acid or another active ingredient. The bait lures worker ants who bring it back to the nest and transfer the poison to other members of the colony, resulting in its eventual destruction. Use ant bait stations along major ant trails and near entry points.

Ant traps like Terro provide the double impact of attracting ants with liquid bait and trapping them so they can no longer access your home. Traps allow you to pinpoint nest locations based on where large amounts become stuck. Replace spent traps until ants are gone.

Since ants often nest outdoors, strategically place baits and traps both inside and along the exterior perimeter of your home for most effective control.

Insect Growth Regulators

Insect growth regulator (IGR) products disrupt the development process of ants, preventing them from properly maturing to adulthood so they cannot reproduce. IGRs lower overall ant numbers over time. Gentrol and Raid Ant Gel are examples of IGR treatments you can apply in inconspicuous areas where ants are active. Reapply monthly.

Professional Pest Control

For very severe ant infestations, it may make sense to hire a professional exterminator. They have access to stronger chemical treatments not available for home use. Professional pest control also removes the hassle and frustrates of tackling the ants yourself. Their expertise identifying nest locations and applying specialized poison baits can eliminate ant colonies more quickly and effectively.

Frequently Asked Questions About Eliminating Ants in Kitchens

How do you know if you have an ant infestation?

Signs of an ant infestation include trails of ants along walls or cabinets, ants near food sources or water leaks, and ants emerging from cracks or holes. Seeing winged ants may indicate a nest inside the walls. Ant spottings in a few isolated areas may simply mean a few scout ants have found your home. Frequent ant sightings, especially in groups, indicate an underlying pest problem.

Why do ants keep coming back after cleaning?

If ants return shortly after removing them, it means they have an established nest nearby and active trails into your home. Cleaning alone won’t deter ants. Removing food sources and moisture should be coupled with sealing entries, applying natural repellents, and using ant poisons to eliminate the colony.

Does vinegar really get rid of ants permanently?

Vinegar kills ants on contact and helps repel future ants. However, it may not eliminate an infestation completely on its own. The effects are short-term, and reapplication is needed frequently. Vinegar is most effective when paired with ant nest removal and sealing entry points.

Are home remedies for ants as effective as chemicals?

Home remedies can be very effective for mild ant invasions. However, severe infestations often require the use of chemical insecticides applied directly into nests and along major ant trails. Using natural deterrents and ant poisons together provide the best chance for getting rid of ants permanently.

How long does it take for ants to die after using boric acid?

Boric acid solutions usually kill off ants within 1-2 weeks. Worker ants ingest the powder and carry it back to the nest, where it spreads and poisons the entire colony over a period of days to weeks. A thorough boric acid treatment will keep killing ants over several weeks before activity ceases completely.

When should I call an exterminator for ants?

Contact a professional exterminator if you have a major infestation, ants return frequently despite your best efforts, or you start noticing structural damage from carpenter ants. Exterminators have commercial-grade chemicals and expertise evaluating nest locations that the average homeowner lacks. This makes them best equipped for severe ant problems.

Prevent Ants from Returning

Getting rid of ants is only half the battle – keeping them away long-term is equally important. Here are tips to prevent future ant headaches after eliminating an infestation:

Maintain vigilance cleaning up food spills and debris where ants congregate
Take out trash and recycling daily
Fix leaky pipes and appliances immediately to avoid moisture
Adjust sprinklers to avoid excessive water collecting near the foundation
Prune trees/plants to avoid contact with the house
Seal as many cracks in walls, windows, and doors as possible
Caulk along the interior and exterior perimeter of your home
Apply boric acid or diatomaceous earth in out-of-sight areas
Place ant baits or traps outdoors around potential entry points

With diligence and persistence, you can get rid of kitchen ants for good. The key is addressing the factors that allow ants to thrive in your home and combining preventative repairs, natural deterrents, and targeted chemical treatments as needed. Maintaining good household hygiene and following ant removal best practices will help you keep your kitchen pest-free in the long run.
