Heavy rain drives ants up from their flooded homes. If the rain has been heavy enough, the entire colony may search out a new place to live. The ants will look for an area that has been unaffected by the flooding, and one of the prime locations is close to a home. Getting rid of these pests can be done by making a simple toxic bait from Borax and sugar. The Borax is poisonous and almost immediately fatal to ants once it has been ingested.
Mix 1 cup of 20 Mule Team Borax with 3 cups of sugar.
Poke holes in the plastic containers, about 1 inch from the top, with the scissors. Make sure the holes are large enough for the ants to enter and exit easily.
Fill the containers halfway with the Borax/sugar mix.
Add enough water to make the sugar syrupy.
Place peanut butter around the rim of the plastic container, and then put the lid on. The smell of the peanut butter will draw the ants to investigate and find the sugar mix.
Place the bait containers around the house near areas you have seen ant activity. The ants will take the bait back to the colony to feed, and kill the queen and other worker ants.
