What Is the Right Way to Mix Boric Acid and Water?
Though boric acid is water soluble, mixing boric acid and water together should be done carefully to avoid the possibility of inhaling boric acid, which, if ingested, is harmful to animals including humans; individuals who are mixing boric acid and water may want to wear a dust mask or some other form of protection during the mixing process. Heating the water prior to mixing in boric acid may be helpful in aiding with quick dissolution.
Boric acid is a common household pesticide that is easy to use and disperse, thanks in part to its ease of solubility in water. Pests like ants and roaches can be killed with a solution of boric acid and water. In some cases, sugar can be added to the boric acid and water solution to attract pests like ants, ensuring they consume the poison.
