Bug Blaster, the trusted, reliable and effective insecticide-free spray has now been reformulated to contain a water soluble polymer that acts as a physical mode of action. The insect is coated with a polymer when Bug Blaster is applied to the insect, the liquid polymer coating immobilises the insect and as a secondary consequence of this film coating, the insect dies. There is no residual action of this formulation as Bug Blaster contains no insecticide and the knockdown is rapid.
