Black ants in your home are often carpenter or sugar ants. Like all ants, black ants are difficult to get rid of, and baits made to kill entire colonies are often ineffective. If you have been unsuccessful with bait traps or you prefer not to use pesticides, you can try several natural ways to get rid of the black ants in your home. Try a combination of methods simultaneously if desired, or just test techniques one at a time until you find one that works for you.
Things You'll Need
- Water bottle
- White vinegar
- Heavy-duty trash bags
- Table salt
- Dried mint
- Cucumber peels

Fill a spray bottle with white vinegar and squirt the ants directly. Also, squirt along trails, entrances and areas where you have spotted ants. Vinegar kills ants and the smell helps deter them from coming back.
Maintain a clean kitchen, including countertops, floor and sink. At the very least, clean nightly before bed, since ants are often most active at night. Mix 1 part white vinegar and 1 part water as a natural home-cleaning solution. Also, vacuum or sweep carpeted and wood floors where food crumbs are dropped.
Take the trash out nightly. Use heavy-duty trash bags to avoid the bag from breaking or leaking as you are removing it from the home.
Follow the ants' trail to find their entrance into your home. Sprinkle this area with table salt or dried mint.
Locate the ant hill outdoors and pour three gallons of boiling water on it. This kills ants in the colony, including possibly the queen. However, black ants often nest inside the structure of your home, in which case this tactic can't be used.
Lay cucumber peels along areas where ants have been spotted. Ants don't like the smell.
