Things You'll Need
Instructions
Get rid of any standing water on your property. Remove catchbasins, water coolers, planters or other equipment that can provide a water source for ants.
Eliminate water sources inside your home. Ants will invade your home in search of a water source. Fix any plumbing leaks and sponge off dish drainers.
Keep your house clean and sanitary to deter ants. Clean up spills and crumbs as they occur, and cover food in tightly sealed containers or in the refrigerator.
Sprinkle some boric acid around baseboards or behind appliances to kill ants that come into your home. Boric acid is deadly to ants and cockroaches but is low in toxicity to people and pets.
Caulk any cracks or holes in your home's foundation to prevent ants from entering. Use weather stripping around windows and doors to eliminate possible entry points for ants.
