Experience

In a recent study in the journal Ticks and Tick-Borne Diseases, just 3 of 100 ticks successfully walked across a surface treated with a DEET solution.

The Centers for Disease Control and Prevention and the Environmental Protection Agency both say that DEET is safe when used properly, even for pregnant women.

DEET has proven to be so effective at repelling ticks that it’s often used as the standard to compare the efficacy of newer repellents, says Lars Eisen, Ph.D., a research entomologist in the Centers for Disease Control and Prevention’s Division of Vector-Borne Diseases.
