How to Kill Indoor Ants

When you see ants in your house, you may be tempted to grab a can of pesticide and kill those you see.
That won't solve the problem, though, and might even cause the ants to split their colonies and make the problem worse. Use a homemade solution that will get poison where it matters -- to the main colony and, hopefully, the queen.

Step 1

Mix one teaspoon of boric acid with 1/3 cup of apple-mint jelly.

Step 2

Place dabs of the mixture on small pieces of cardboard and place the baits where you have seen ant activity. Place three dabs in about every 25 square feet of area. Make sure your pets and children can't get to the mixture because it is poisonous. The ants will be attracted to the mixture and will take traces of the poison back to the colony.

Step 3

Check the baits every couple of days and apply more bait or add a couple drops of water to dried-up bait.

Things You Will Need
