On a rainy day, you may see hordes of ants marching into your house. They're searching for dry shelter, food and water, and who can blame them even if they're unwelcome guests? Here's how to ward off these industrious fellows.
Steps:
1. Follow the ant line to its source. It might be a window, molding crevice or floor crack.
2. Form a temporary barrier at the source with boric acid or laundry detergent in powder form.
3. Remove any food the ants have attacked and discard it in a garbage can outside your house.
4. If the ants have invaded the kitchen garbage can, bring it outside, hose it down and wash it with dishwashing liquid and water.
5. Put food the ants have not found in zipper-lock plastic bags or in plastic containers with sealable lids. Or put these items in the refrigerator.
6. Remember that ants can penetrate metal-threaded lids on glass jars. Seal these jars in zipper-lock plastic bags. Glass jars are immune from ants only when sealed with a rubber gasket.
7. Seal all food items in your cupboards, especially sugar, honey, maple syrup, grains, cereals, cookies, jams and breads.
8. Once you've secured the food, vacuum up the ant line, along with a bit of cornstarch, which helps suffocate them inside the bag. Or wash them away with dishwashing liquid, water and a rag if you prefer.
9. Use dishwashing liquid and hot water to wash the area around the ant line and erase any scent of the trail.
10. Seal the area where the ants entered; caulk windows and cracks and weather-strip doors (see How to Fix a Drafty Door). Apply duct tape or petroleum jelly over holes as a temporary fix.
11. Go outside and see if you can determine where the ants entered the house. If they used a branch as a bridge to the house, trim it.
12. Check the area in an hour. If you see any single ants, or scouts, searching the area, squash them. They're scoping out the area for future invasions.
13. If you wish to wipe out the ant population, use ant traps that contain boric acid. The returning ants poison the entire colony. Ants play a beneficial role in gardens, however, so only do this if absolutely necessary.
Overall Tips:
Some natural ant deterrents include crumbled bay leaves, cinnamon, peppermint leaves and cayenne pepper.
If an indoor plant is infested with ants, bring it outside and flood it several times with a hose to remove them.
Insecticidal sprays kill only the ants you spray--a very small percentage of the colony--and won't prevent future invasions. If you use a spray, keep children and pets away from sprayed areas.
Overall Warnings:
Carpenter ants, which are large with smooth backs, burrow into wood and cause structural damage. Keep piles of decaying wood away from the house as this attracts them.
