Deltamethrin is a synthetic pyrethroid—which means that it is effective for longer periods of time.
Deltamethrin belongs to a class of insecticides known as synthetic pyrethroids. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like deltamethrin, are often preferred to the real thing as an active ingredient because they offer the added bonus of remaining effective for longer periods of time.
Deltamethrin is a long-established and proven synthetic derivative of the natural insecticide pyrethrum. It has a very high level of safety at approved use rates and has a number of important uses World-wide. It is one of the main compounds used in the fight against malaria-carrying-mosquitoes (both as an indoor spray but also for the treatment of mosquito bed-nets).
Deltamethrin provides excellent knock-down, affecting a specific area of the insect’s nervous system. Insects are much more susceptible to deltamethrin than humans, other mammals and birds. More importantly, it is safe to use in the home around family and pets as it binds tightly to surfaces where it is applied, and is not readily dislodged. It is not volatile, so no airborne residues are generated after spray droplets have settled.
