Common Causes of Ants in Dishwashers

Ants are attracted to dishwashers due to the presence of food residue and moisture. Food particles left on dishes or inside the dishwasher can attract ants, as they feed on a wide range of organic matter.

Moisture is another factor that attracts ants to dishwashers. The warm, humid environment inside a dishwasher after a wash cycle provides an ideal habitat for ants to thrive.

Food Residue

Food residue can accumulate in various parts of the dishwasher, including the filter, drain, and around the door seals. When food particles are not thoroughly removed, they can attract ants and provide a food source for them.


Moisture can enter the dishwasher through various sources, such as condensation from the wash cycle, leaks in the water supply line, or improper drainage. The warm, humid environment inside the dishwasher creates a favorable condition for ants to nest and reproduce.

Preventive Measures

Preventing ants from invading your dishwasher is crucial to maintain a clean and pest-free appliance. Regular cleaning and maintenance are essential steps to deter these tiny invaders.

Cleaning the Dishwasher Filter

A clogged dishwasher filter can accumulate food debris, attracting ants. Clean the filter regularly by removing it and rinsing it thoroughly with water. Ensure no food particles or grease remain on the filter before reinserting it.

Removing Food Debris

Food debris left inside the dishwasher can entice ants. After each wash cycle, check the dishwasher for any remaining food particles. Wipe down the interior with a damp cloth or sponge to remove crumbs and spills.

Keeping the Dishwasher Dry

Moisture attracts ants. Keep the dishwasher dry by leaving the door slightly ajar after each wash cycle to allow air to circulate and prevent moisture buildup. You can also use a dishwasher drying agent to help remove excess moisture.

Natural Remedies

Ants in the dishwasher can be a nuisance. Fortunately, there are several natural remedies that can help you get rid of them without resorting to harsh chemicals.

Here are some effective natural ant repellents:

  • Vinegar: Ants despise the strong odor of vinegar. You can mix equal parts vinegar and water in a spray bottle and spray it around the dishwasher, paying particular attention to areas where ants tend to congregate.
  • Lemon juice: Similar to vinegar, lemon juice has a strong scent that ants find unappealing. You can use fresh lemon juice or mix lemon essential oil with water in a spray bottle and apply it around the dishwasher.
  • Essential oils: Certain essential oils, such as peppermint, tea tree oil, and cinnamon oil, have strong scents that repel ants. You can add a few drops of these oils to a diffuser or mix them with water in a spray bottle and spray them around the dishwasher.

In addition to these liquid repellents, you can also use solid substances to deter ants:

  • Borax: Borax is a natural mineral that is toxic to ants. You can sprinkle borax around the dishwasher, but keep it away from pets and children.
  • Diatomaceous earth: Diatomaceous earth is a fine powder made from the fossilized remains of diatoms. It is abrasive to insects and can cause them to dehydrate. You can sprinkle diatomaceous earth around the dishwasher, but avoid inhaling it.

Chemical Solutions: How To Get Rid Of Ants In Dishwasher

If natural remedies fail to deter ants, you can resort to chemical solutions. These methods are more potent but require cautious handling.

Commercial Ant Baits and Traps

Commercial ant baits and traps are designed to attract ants with sweet or protein-based lures. Once the ants take the bait, they carry it back to their colony, eliminating the entire infestation. Place these baits in areas where ants are frequently sighted.

Ant Spray or Powder

Ant spray or powder can be applied directly to ant trails or their entry points. These products contain insecticides that kill ants on contact. Ensure you follow the instructions carefully and take precautions to avoid inhaling or touching the chemicals.

Precautions When Using Chemical Solutions, How to get rid of ants in dishwasher

  • Keep chemical solutions out of reach of children and pets.
  • Wear gloves and a mask when applying ant spray or powder.
  • Ventilate the area thoroughly after using chemical solutions.
  • Dispose of used baits and traps properly.

Physical Barriers

To prevent ants from entering your dishwasher, it’s crucial to create physical barriers that they cannot penetrate. This involves sealing potential entry points and implementing measures that deter them from accessing the dishwasher.

Caulking and Sealing

Thoroughly inspect the dishwasher’s exterior for any cracks, gaps, or holes. Use caulk or sealant to fill these openings, effectively blocking ants from crawling through them. Pay particular attention to areas where hoses and wires enter the dishwasher, as these are common entry points.

Ant Traps and Barriers

Ant traps or barriers can be placed around the dishwasher’s perimeter to intercept ants before they reach the appliance. These traps contain bait that attracts ants, trapping them before they can enter the dishwasher.

Physical Barriers Using Chalk or Petroleum Jelly

Creating a physical barrier using chalk or petroleum jelly can also deter ants. Draw a line of chalk around the dishwasher’s base, as ants are reluctant to cross it. Alternatively, apply a thin layer of petroleum jelly around the dishwasher’s exterior, creating a slippery surface that makes it difficult for ants to climb.
