Does Boric Acid Kill Termites

Boric acid The Natural Termite Cure.

Boric acid, has the chemical formula H3BO3, sometimes written as B(OH)3, when dissolved in water, it is used as an insecticide. It is mined as borate from Death Valley and then undergoes a refining process to extract white crystals.

Boric acid is toxic by inhalation or if taken internally. Long term exposure to boric acid may not be healthy because research studies on dogs have shown that they develop testicular cancer, however there has been no human studies.

P.F. Harris invented the Roach Tablet in 1922 and he was the first to impregnate a tablet with boric acid as an insecticide, since then the U.S. Patent Office has had over two hundred different products registered with the same principal. Framing Lumber, a New Foundland lumber company, expanded the idea and started to treat their timber with boric acid in the fifties. Since that time there is no record of any wood being treated with boric acid and then been attacked by termites.

One of the advantages is that it is cheap and easy to get hold of any drug store or pharmacist stocks the product. Most of the commercial insecticides for termites contain boric acid in some form, either in the baits or as tablets.

One of the most effective ways to use boric acid is to make your own bait traps. Soak some wood in boric acid crystals melted in boiling water and then bury the wood in the ground near an infestation. Monitor where you have laid the baits traps and replenish them when they have been eaten. The wood you have buried the more effective the bait traps. Each termite nest has hundreds of thousands of termites and in some cases millions. As the termites carry the wood back to the colony it is stored and then eaten later. Eventually the boric acid will be eaten and it will wipe out the colony.

Boric acid works as a stomach poison to the insects and the dry powder dehydrates their exoskeleton. Homemade bait can be made by dissolving 1 teaspoon pf powdered boric acid and 10 teaspoons sugar into 2 cups of water. Soak the wood in this solution. Boric acid in this concentration is also effective against ants as well as termites.
