Boric acid kills ticks by sticking to their legs and causing dehydration and poisoning of the food supply when they return to the colony.
Many commercial tick and other insect control products contain boric acid as the “secret ingredient.” This naturally white, powdery substance is odorless and more environmentally friendly than most insecticides.
Sprinkle boric acid in your home and yard or places where you know ticks are located. By creating a layer that ticks must crawl over, you will ensure the substance will reach the nervous system.
Apply boric acid to an embedded tick to kill and remove the tick. Boric acid also works as a disinfectant and wound healing agent once the tick is removed.
While boric acid is a relatively nontoxic chemical, it may damage or kill plants and plant roots. It is also toxic when consumed in large doses by children and animals.
