Make your own anticide using the active ingredient in Ant-Rid:
1. Grind and mix well equal portions (by volume) of sodium borate (aka 20 Mule-Team Borax) and plain table sugar using a mortar and pestle. I use about a teaspoon of each, storing extra in a small ziplock bag.
2. Sprinkle about 1/4 to 1/2 teaspoon of the mix in a very shallow container, such as a jar lid.
3. Use a spray bottle to slightly dampen the powder; stir around a bit. You don't want it to be sloppy wet.
4. Set the lid(s) wherever you see ants.
5. Bye-bye ants!
