Peppermint Spray  

If you love the refreshing scent of peppermint, ants decidedly do not.

Create a peppermint spray by mixing water with peppermint essential oil and generously spray it near the entry points and along their trails.

Lemon Juice 

Lemon juice is more than just a refreshing drink on a hot day; it’s also an ant deterrent! Squeeze some fresh lemon juice near wall cracks and crevices where ants may be sneaking in. 

Sugar and Borax Bait  

This one’s a bit sneaky, but highly effective. Mix equal parts sugar and borax, and sprinkle this deadly bait near ant entry points.

The sugar lures them in, while the borax spells doom for the unsuspecting ants.

Soap Water Spray 

This simple solution is a game-changer. Mix a few drops of dish soap with water and spray it directly on the ants.

The soap breaks down their exoskeleton, causing them to dehydrate and perish.


Cinnamon doesn’t just add a warm, cozy aroma to your baked goods; it also disrupts ant trails.

Sprinkle cinnamon powder near ant-infested areas, and they’ll think twice before crossing it.

Cayenne Pepper or Black Pepper

Spice up your ant control with some cayenne pepper or black pepper.

Ants despise these fiery spices, so sprinkle some near their entry points or along their trails.


Time for some burning questions and their concise, straightforward answers!
