1 part hydrogen peroxide
8 parts water
Mix the hydrogen peroxide and water. Soak stain for 5 to 30 minutes. Launder as usual.
Baby powder or cornstarch
Pour enough baby power or cornstarch on the area of the stain to soak up oil. Wait a few minutes. Launder as directed on instruction tag.
2 to 3 ounces vinegar
1/2 tsp dishwashing liquid
Pour vinegar and dishwashing liquid into a spray bottle.
1 teaspoon boric acid (available at any drugstore)
6 tablespoons sugar
2 cups water
Thoroughly dissolve the boric acid and sugar in the water. Do this in a clear jar so you can see when all the boric acid crystals are dissolved. Then soak some cotton balls in the bait solution.
Make bait dispensers out of some old plastic cartons with lids. Punch holes in them so the ants can get inside, then put the soaked cotton balls into the containers and cover them with lids so the bait won’t dry out.
Place the bait containers wherever you see ant trails, in and/or outside the house.
Clean the containers and use fresh bait solution at least once a week.
Be patient! The key to effective control is to get worker ants to continually carry low doses of boric acid back to feed the ants in their nest. After a few weeks of using the solution, reduce the boric acid content even further, to 1/2 teaspoon, and use this weaker solution for long-term control. Boric acid is mildly repellent to ants, and using a very low dose makes it more likely that surviving ants will continue eating the bait and taking it back to the nest.
