½ cup (100 grams) of sugar 1 ½ tablespoons borax 1 ½ cups (350 milliliters) warm water A jar Cotton balls Shallow dishes, small containers, or lids (optional)
If you don’t want to get your floors or window ledges dirty and sticky, you can place the soaked cotton ball in a small container first, and then set the container out. You can also use a shallow dish or a jar lid. Whatever container you chose to use, make sure that you don’t use it for food purposes again. Borax is very toxic to humans and pets as well.
Make sure that you won’t be using the container or utensil again for cooking or eating.
Alternatively, you can use a small puffer or duster to coat surfaces with borax so ants are less likely to see and avoid it. [6] X Expert Source Kevin CarrilloMMPC, Pest Control Specialist Expert Interview. 22 October 2019.
