Permethrin is over 2,250 times more toxic to ticks than it is to humans, and when applied to skin, less than 1% of the active ingredient is typically absorbed [1.12.1]. Understanding how toxic is permethrin to humans depends on the route of exposure and concentration.

The pivotal question remains: **is permethrin toxic to humans?** While its effectiveness is clear, understanding its safety profile is crucial for both medical and environmental applications.
