Insect Repellents

Insect repellents are chemical substances that, when applied on the skin, are able to repel insects and block their attack on man. These compounds can block the insect’s approach phase to the host by deviating the flight and hence taking the insect far from the target. Insect repellents exploit their action on many insects such as mosquitoes, flies, sandflies, horseflies, fleas, mites and ticks. There are three categories of insect repellents: Physical repellents Synthetic repellents Natural-origin repellents
