I read this recipe from Wikipedia.org:

Insecticidal

Boric acid was first registered in the US as an insecticide in 1948 for control of cockroaches, termites, fire ants, fleas, silverfish, and many other insects.[11] It acts as a stomach poison affecting the insects’ metabolism, and the dry powder is abrasive to the insects’ exoskeleton.

Boric acid is generally considered to be safe to use in household kitchens to control cockroaches and ants. Homemade ant bait can be made by dissolving 1 teaspoon powdered boric acid and 10 teaspoons sugar into 2 cups (500 mL) of water; this mixture can then be absorbed into cotton balls which are left near ant trails. This reportedly will be carried back into the ants’ nest, killing any ants that eat it, potentially destroying the entire colony.

I did the procedure but I dont understand what they meant by “this mixture can then be absorbed into cotton balls” because it never formed those balls.. the boric acid and the sugar totally dissolved in the water with just very tiny whites floating.. are those tiny whites it???

Does anyone have a different way of doing it?
