Boric acid can be bought at most pharmacies or groceries stores in powdered or granular form. Use boric acid to kill pest insects with information from a professional landscaper in this free video on pest control.
I'm Bill Elzey with Showplace Lawns. Where can you buy boric acid? Boric acid is found at the local pharmacy and at the grocery store. Boric acid is used for insect control. Most times, boric acid is a powder or a granular substance. And by just merely placing it in some areas, it will attract the insects to it. Then the insects as they eat this stuff develop a sort of digestive problem and thus eliminates the insect. Don't need to scatter it. Just maybe against a crack or something like that or sit it out in some little containers so the insects are attracted to it. Again, you make, you can find the boric acid at the pharmacy or at the grocery store.
