Boric acid is a white, powdery chemical compound that has many practical uses, especially for killing insects and other pests. You might find it in ant traps or roach powder that people use to protect their homes. When insects walk through boric acid, it sticks to their bodies and eventually poisons them.

Scientists extract boron from certain rocks and minerals and combine it with other elements to create boric acid. Beyond pest control, people use boric acid in some medical products, in certain eye wash solutions, and even in some science experiments because it affects how flames burn (turning them green).

While boric acid works well for its intended purposes, it needs to be handled carefully. It can be harmful if swallowed or if too much gets on the skin, which is why products containing it usually come with clear warning labels. Adults keep it stored safely away from young children and pets, just like other household chemicals.

It has been used for over a century, making it one of those reliable substances that people have trusted for generations to solve specific problems around the house.
