While most ants are beneficial as they help control pests like flies and aphids, their invasion into your kitchen cabinets can be quite distressing. Fortunately, there are several methods to eradicate ants, such as spraying them with lemon juice or peppermint oil. If gentle measures fail, you can escalate the battle using ant traps and insecticidal chemicals.
Steps
Eradicating Ants
Sometimes, eliminating ants becomes necessary when they spread uncontrollably without any signs of stopping. Although not the ideal choice, this method should be considered when ants persistently invade your home.
Start with the least harmful methods before escalating to stronger measures. This approach is not only better for your health but also more environmentally friendly.
Disrupt the ants' trail. You can effectively and quickly deal with a marching line of ants by eliminating the ants in the line and preventing others from following their path. Identify the entry point where ants are invading your home and create a barrier, such as using Vaseline, sticky tape, or talcum powder to block the ants' access. Then, try one of the following methods to handle the ant trail:
- Dip a sponge in soapy water. Simply wipe the sponge along the ant trail to gather and rinse the ants away. Repeat as necessary until the entire trail is cleared.
- Use a multipurpose cleaner or bleach solution to spray on the ant trail. Wipe clean with a damp paper towel. Spraying the nest can also be effective, but ensure the entire nest is eradicated, as partially destroying it may encourage some species to establish new colonies, which could worsen the problem.
Eliminate scout ants. Ant colonies often send out individual ants to search for food sources. If you spot a lone ant wandering on your countertop, do not let it survive and return to its nest. It will alert the entire colony to the spilled apple juice. If the scout ant returns with reinforcements, they will follow the scent trail in a single file. Unless you plan to use bait, quickly eliminate the ants.
Eradicate ants that have settled in your pantry or dish cabinets. Use a highly attractive toxic bait to lure the ants into carrying the "spoils" back to their nest. A mixture of boric acid or borax with water and sugar is the most common ant bait. Boric acid affects ants both externally (as a powder; similar to diatomaceous earth) and internally (when ingested). Mix 1 cup of water, 2 cups of sugar, and 2 tablespoons of boric acid.
- Wait for the ants to appear. Avoid using bait to attract new ants, as it may draw in additional colonies. Once an ant trail appears, place the bait near the trail (not directly on it, as this may disrupt their return path). You can also place the bait in a secure spot in your pantry where ants frequently gather.
- If you have small children or pets (see the warning below), place the bait in a jam jar where ants can access the "food." Secure the lid and tape it shut. Poke two or three small holes in the lid large enough for ants to enter, then apply a non-toxic lure outside to advertise the treat inside. If you're concerned about the jar tipping over, place a cotton ball inside the jar above the bait.
- You can also use peanut butter. Ants' preferences vary depending on the colony's needs (sometimes sweet, sometimes greasy), so offering both increases the likelihood they will take the bait. Once the ants have fed, clean up the bait, as the toxin may lose effectiveness over time but still attract ants. You wouldn't want to attract a neighboring colony, would you?
Consider making homemade borax bait. Mix 1 tablespoon of peanut butter, 2 tablespoons of sugar, 2 teaspoons of borax, and 1 teaspoon of water. Blend thoroughly. Spread a small amount on a piece of cardboard and place it where ants congregate. Watch as they gather and carry the bait back to their nest.
- If the ants die too quickly, try using only 1.5 teaspoons of borax. The goal is for them to carry the bait back to the nest and eliminate the entire colony, including the queen.
Use a vacuum cleaner to suck up ants. Sprinkle some baby powder or diatomaceous earth on the ants, then finish them off by vacuuming them up and disposing of them in the trash. This second step is crucial to ensure that the ants don’t establish a new colony inside your vacuum cleaner.
Create a mixture of rubbing alcohol, dish soap, and water. Take a spray bottle—make sure it’s thoroughly cleaned—and add about 1 teaspoon of rubbing alcohol and 1.5 teaspoons of dish soap. Then fill the bottle with water, leaving about 2.5 cm from the top, and tighten the lid. Shake the bottle until bubbles form, and you’re ready to spray! The alcohol in the solution will effectively wipe out the ants.
Purchase a "Deep Reach" insecticide spray. This method can eliminate ants for 6-8 months, but the downside is that you’ll need to avoid the sprayed area for several hours to a few days. Be sure to read product reviews online and ask for it at home maintenance stores. You’ll need to know the area you’re treating. If you’re concerned about using potentially toxic chemicals indoors, this may not be the best solution. Avoid this method if you have young children, as their immune systems are still developing.
Attack the ant nest
This method is the least recommended—ants play a vital role in your garden and the broader ecosystem, as they help control many garden pests. Completely eliminating ants could disrupt the delicate balance of the environment and disturb the harmonious coexistence humans strive for. However, if ants are foraging or nesting in play areas or inside your home, you may need to remove them. Here are some suggestions.
Locate the ant nest. Once you find the source, carefully dig or poke into the ground and pour several liters of boiling water into the ant nest. This method can effectively eliminate the entire ant colony.
Try a homemade solution. Mix one part camphor oil with nine parts ethyl alcohol (the type with additives to make it undrinkable) or denatured alcohol containing toxic, non-consumable alcohol. Pour this mixture into the ant nest.
Eliminate the queen ant. The most effective way to eradicate ants is to destroy their source: the queen ant. The queen produces a vast number of ants, and killing her will end the colony. If possible, locate and eliminate the queen inside the nest. She is often shy and hides deep within. This method is not recommended for aggressive or biting ant species.
Keep your home clean
Persistently discourage ants from returning by ensuring your home is free of food that attracts them. Cleaning up food crumbs and enticing debris is a crucial step in eradicating ants and preventing them from entering your home.
Store food in airtight containers. This not only keeps food fresher but also traps any insect eggs inside. When the larvae hatch, they remain confined, making it easier to dispose of them and preventing an infestation in your pantry. Investing in high-quality food storage containers is well worth it.
Wipe down all surfaces. Regularly spray and clean countertops and cabinets with a mild bleach solution or vinegar mixture.
Develop a cleaning routine. Sweep, mop, and vacuum your home frequently to maintain cleanliness.
Keep sinks clean. Avoid leaving dirty dishes and standing water, which attract ants, and ensure no food debris clogs the drain. Regularly clear out any leftover scraps in the sink.
Place pet food bowls inside a larger dish. Fill the larger dish with water to create a 'moat' around the pet food bowl, making it difficult for ants to reach the food.
Prevent ants from entering your home
The best way to eliminate household pests is to deter them from even considering your home as a target. Therefore, repellents are a key focus for homeowners whose properties are prone to ant invasions.
Establish a defense line for your home. Due to their tiny size, ants can find countless entry points into your living space. Some of these paths are easy to spot, while others only become apparent when you notice a trail of ants marching through.
Use caulk. Seal windows, doors, and any cracks ants might crawl through using caulk. An added benefit is improved temperature control indoors, which can help reduce energy costs. Additionally, this method is low-risk for homes with children and pets.
Apply ant repellents around suspected entry points. Salt, chalk, baby powder, and talcum powder can be sprinkled under doors, near windows, and along walls.
- Note that there are concerns about the potential cancer risks associated with talcum powder.
Use substances and scents that ants dislike. Vinegar, peppermint oil, cinnamon, black pepper, cayenne pepper, cloves, and bay leaves are commonly believed to repel ants. However, some of these may harm pets or irritate curious children.
Create a protective buffer zone around your home. Ants often enter through bushes, trees, or overhanging branches. To address this, establish a dry, vegetation-free boundary by trimming overhanging branches and pruning plants that touch the house. Additionally, spread gravel or stones around the perimeter.
Tips
- Declutter your home, such as disposing of old furniture or newspapers, before starting ant control. Ants can hide anywhere, and you don’t want to think you’ve eliminated them only to find they’re still around!
- Clean up after meals and pet feeding. Ensure empty soda cans are discarded and living spaces remain tidy.
- Ants are attracted to aphids and scale insects, especially the sweet secretions they produce. Control aphids and scale insects on garden plants during spring and summer (when they thrive), and ants will be less likely to linger for food.
- If ants invade your trash bin, keep it outside.
- Many online sources recommend yellow cornmeal for ant control; some claim it works, while others argue it only disrupts their trails and nests without eliminating them.
- For quick, temporary solutions, multipurpose disinfectant sprays like Lysol or Windex can poison and kill ants within minutes. However, be prepared for extensive cleanup, and it may spread. This method typically only kills visible ants in accessible areas, not entire colonies.
- Sprinkle raw oats on small ant mounds. Ants will eat the oats, swell, and die.
- Apply ant powder in dark, damp corners, baseboards, or cabinets around the house. Use it only in areas inaccessible to people. (Check product instructions if unsure).
- Exercise caution with ant repellents, as they can harm you too. Avoid inhalation and keep pets away when spraying or applying chemicals.
- Do not use repellents near ant bait stations. Ants will avoid the area, rendering the bait ineffective.
- Use a lint roller to quickly and effectively remove ant trails.
- Almost any chemical cleaning spray can kill ants.
Warnings
- If an adult ingests a teaspoon of boric acid, drink two glasses of water and seek medical attention immediately.
- Wear gloves and a mask when handling ant-killing substances. At best, they can cause irritation; at worst, they can be toxic. Safety goggles are also recommended, especially when using spray insecticides. Opt for close-fitting goggles (not just those designed to block wood shavings, though some protection is better than none).
- Boric acid may be less effective in warm weather; consider using this method more frequently during spring.
- Store ant-killing products out of reach of children and pets. Many are highly toxic and should be kept in secure cabinets or high places. Always follow the instructions on the packaging.
- Planting mint around your home and garden can deter ants, but mint is invasive. Consult gardening centers before planting it directly in the ground.
- Boric acid or borax can have adverse effects upon contact. These substances may irritate the eyes; if exposed, rinse thoroughly and seek medical care if symptoms persist for more than 30 minutes.
