Set out cucumber peels or slices in the kitchen or at the ants’ point of entry. Many ants have a natural aversion to cucumber.
Leave a few tea bags of mint tea near areas where the ants seem most active.
BLOCK THE ENTRY
Trace the ant column back to their point of entry. Set any of the following items at the entry area in a small line, which ants will not cross: cayenne pepper, citrus oil (can be soaked into a piece of string), lemon juice, cinnamon or coffee grounds.
LIGHT IT UP
Leave a small, night light on for a few nights in the area of most ant activity. The change in light can disrupt and discourage their foraging patterns.
BUILD A MOAT
If ants are attacking your pets’ food bowls, clean the floor thoroughly with hot, soapy water to eliminate the ants’ trail, then keep them from finding the food dish again by placing the food bowl into a shallow pan of soapy water
Diatomacious Earth (often referred to as “DE”) is a talc-like powder that is the fossilized remains of marine phytoplankton. When sprinkled on a bug the fine powder absorbs lipids from the waxy outer layer of insects’ exoskeletons, causing them to dehydrate.
Put small piles of cornmeal where you see ants. They eat it, take it ‘home,’ can’t digest it, and expire. It may take a week or so, especially if it rains, but it works and you don’t have the worry about pets or small children being harmed!
HOMEMADE ANT BAIT
Dissolve 1 teaspoon of boric acid and 6 tablespoons of sugar in 2 cups of water. Soak cotton balls in this bait solution. (Boric acid is a low-toxicity mineral, but do keep it away from children and pets because it can cause skin, mouth, stomach, and eye irritation.)
Place one or two cotton balls on an inverted jar lid and saturate with the mixture.
Place the jar lids along ant trails or where ants have been seen.
Replenish the liquid as it dries until the ants are gone.
Be patient! The key is to get worker ants to continually carry low doses of boric acid back to feed the ants in their nest.
