How to Get Rid of Ants
Put an end to most ant problems with inexpensive products from the home center or hardware store, and save the expense of hiring an exterminator.
I.D. the Ant
Keep it Clean to Deter Ants
A clean house is your first defense against ants. Sweep up food crumbs, wipe up spills, take out the garbage and don’t leave dirty dishes sitting around the house. This takes away the ants’ food source. Spray vinegar mixed with water around bowls of pet food to keep ants from feasting there.
Erase Ant Trails
Where you see one ant, you’re bound to see others. That’s because ants leave a scented trail that other ants follow. Sweeping or mopping isn’t enough to eliminate the scent. Instead, mix 1 part vinegar with 3 parts water in a spray bottle, then spray wherever you’ve seen ants in the past. This will stop outdoor nesting ants that entered the house to forage for food (ants that come inside are not necessarily trying to establish a nest).
Vinegar and water won’t stop ants that are already nesting indoors. You’ll need to kill them with ant bait.
Determine the Best Ant Bait
Prebait ants in areas you’ve previously seen them. Ants’ tastes change during the year. They usually prefer protein in the spring and sweets or fatty/oily foods in the summer. Set out sugar or honey, fried food and peanut butter, then see which food attracts ants. Use whichever food they prefer for bait.
Once you know what the ants like, buy and set out toxic ant bait that’s geared to their taste. Look on the bait package for words like “controls both sweet and grease eating ants.”
Wipe Out Ant Colonies
is the best way to kill ants for many sweet-loving ants. Other ants prefer solid bait. If you still have ants in house after two weeks, replace the bait containers. If that doesn’t work, how to get rid of ants next means finding the nest.
Find Ant Nests
Cut small holes in water-damaged walls to track down the ant nest. (You’re going to have to repair the walls anyway.) When you find the nest, spray it with an insecticide that contains bifenthrin, permethrin or deltamethrin (look on the label). is one brand. Be sure to fix the water leak and replace damaged wood. If you can’t track down the nest, hire a pest control service. Pros spend about 80 percent of their time hunting down nests. Their fees start at about $150, but tough cases with multiple treatments can cost $400 or more.
