Insect repellents are substances applied on to the surfaces, skin or clothes to prevent insects from landing or climbing on them. Synthetic repellents are more effective and long lasting than natural repellents. These repellents help to prevent and control the outbreak of insect-borne diseases like malaria, dengue fever, bubonic plague etc. Insects such as flea, fly, mosquito and tick are the common vectors for carrying these diseases.
