A cheery thought.......

Permethrin is used in tropical areas to prevent mosquito-borne disease such as dengue fever and malaria. Mosquito nets used to cover beds may be treated with a solution of permethrin. This increases the effectiveness of the bed net by killing parasitic insects before they are able to find gaps or holes in the net. Malaria kills about 3 million people per year, and permethrin is believed to have very low if any toxicity (yeah, right!)in humans. Military personnel in malaria-endemic areas (like Afghanistan) may be instructed to treat their uniforms with permethrin as well. An application should last several washes.

As permethrin is a benzene based chemical , it is probably not very good for you! It is a neuro toxin, and affects neuron membranes.
