Ants are some of the most common pests in lawns and houses. Although most ant species are harmless to humans, ants can infest a house in search of food. Some species -- such as carpenter ants -- may even weaken the wooden structure of a house. Boric acid, the active ingredient in borax, can be an effective means of ant control. Borax is preferred over some other ant control products because it is considered safe around animals and children.
Mix 2 2/3 tbsp. borax, 1 2/3 cup sugar, and 1 gallon of warm water in a large pot or mixing bowl. Stir the mixture until the sugar and borax dissolve. The warmer the water, the quicker the sugar will dissolve.
Pour the solution into a garden sprayer tank according to the directions of your sprayer.
Spray the borax solution around the perimeter of the ant nest or any other problem areas. Any sprayed surface must be thoroughly saturated to ensure it leaves enough sugar to attract the ants, and enough borax to kill them. Several small puddles around the perimeter of the ant nest make an effective and lethal bait.
Repeat the process on a daily basis until the ants die or move to a new location.
