In the summer months, armies of ants invade many homes and gardens. For many homeowners, it can feel like a losing battle trying to fight thousands of ants with sprays, powders and traps. This battle becomes even more challenging for those determined to get rid of ants without resorting to harmful chemicals. Fortunately, a number of organic products may be effective at fighting ants without posing a health risk to family, pets or the environment.
Water
It's hard to find an ant-control product that's more natural than water. If fire ants in your garden pose a threat to your children or pets, Oklahoma State University recommends pouring boiling hot water directly onto the mound. Use extreme caution to avoid burns when transporting the water, and plan to apply about 3 gallons of water to each mound. The ants that aren't killed right away will be traumatized enough to steer clear of your yard.
If you feel this method is too dangerous, North Carolina State University recommends filling a bucket with warm soapy water. Carefully dig the mound out with a shovel and drop it into the water to kill ants naturally.
Boric Acid
Boric acid is an all-natural mineral found all over the world. According to the North Dakota State University Extension Service, boric acid also offers an effective way to kill ants organically. Mix one cup water, one-half cup sugar and 1-1/2 teaspoons boric acid in a jar and shake well. Pour this solution into a series of jars, then fill each jar with cotton balls. Punch holes in the top of each jar and leave them around your home to act as ant traps. The ants carry the boric acid back to the hive, where it acts as a poison to kill off the entire colony.
Diatomaceous Earth
Diatomaceous earth consists of finely-ground rock and small fossilized algae or sea creatures. According to the University of California Integrated Pest Management Program, this product offers a non-toxic method of ant control that remains effective as long as it stays dry. When ants consume diatomaceous earth, it dries out their exoskeletons, leaving them dead or extremely vulnerable. Sprinkle this product indoors and out, but keep it protected from moisture to maximize ant control. If you have small children or pets in your household, you may want to purchase food-grade diatomaceous earth, which is safe for human and animal consumption.
Grits
Horticulturists at North Dakota State University Expansion suggest leaving grits out for ants to feast on. When ants consume dry grits, the food expands in their stomach and kills them. This method of ant control takes time, but requires no harmful chemicals.
