Who sells boric acid?

Boric acid is available in its pure form through hardware stores, drug stores, home improvement stores and other online and physical stores that sell insecticides and similar products. Used for a variety of applications, boric acid is available over-the-counter and is typically unrestricted, but it is toxic and can be dangerous to humans and domesticated animals if ingested.

While boric acid is commonly used as an insecticide to kill household pests such as cockroaches, this natural chemical can also be used as an algaecide, fungicide and herbicide. This substance is intended to kill unwanted pests, so it should be handled and used with care.
