Barrettine’s Bug Blaster has been designed to be a trusted, reliable and effective insecticide-free spray and aerosol, it has now been reformulated to contain a water soluble polymer that acts with a physical mode of action. 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, says the company. The product is recommended to be used against small nuisance insects appearing around the home, such as flies, ants, bed bugs and fleas.
