Home Remedies to Get Rid of Big Black Ants

Updated February 21, 2017

If big black ants have invaded your home, chances are that they are carpenter ants, which are very destructive to a home. They don't eat the wood of your house; rather, carpenter ants want to make your home into pulp for the construction of a nest. Carpenter ants are notoriously difficult to get rid of, so it is in your best interests to consult a licensed and bonded exterminator. However, a number of home remedies will get rid of these big black ants for those who would rather do it themselves.

Get Rid of Nests

The only way to thoroughly eliminate carpenter ants from your home is to eliminate the nest. You must first find the nest somewhere in your home, and it is generally difficult to locate. In fact, there are two different kind of nests: the parent nest and the satellite nests. You must find the parent nest and can locate any carpenter ant nest by tapping the walls until you hear a hollow sound indicative of decaying, damaged wood. Thoroughly spray the nest area with pesticide.

Bait the Ants

If you are experiencing difficulty locating the nest, or the nest is located in an area that you cannot access, consider other ways to eliminate an invasion of carpenter ants. Bait ant food with a combination of 1 per cent boric acid and 10 per cent sugar water. This method is much more ecologically friendly, but it takes weeks or months to fully work. Do not combine pesticide with food as this will kill the worker ants before they return to the nest with the food. Always keep this mixture away from pets and children because it is harmful.

Spray Boric Acid

Electrical wiring is a preferred method of travel for big black ants. One way to ensure that ants eat boric acid, which is poisonous to them, is to spray boric acid through electrical sockets. Take care that you do not shock yourself when you spray the boric acid.

Use Baking Soda

Ants cannot expel gas from their system, so baking soda is a poisonous substance to them. Similar to the boric acid mixture, create a mixture of baking soda and a food that carpenter ants would want to eat. Icing sugar mixes well with baking soda. Mix the two in equal proportion, and leave it somewhere you know the ants go.
