Pest Expert Formula 'P' Fumers are carpet beetle smoke bombs for fumigating carpet beetle infestations. Once lit, they release a smoke which can penetrate into cracks and crevices to kill carpet beetles harbouring there.
Formula 'P' Fumers contain the powerful carpet beetle killing insecticide permethrin (13.25% w/w).
Each 3.5g Fumer will treat an area of approx 30 cubic m, so you will need to use 1-2 Fumers for an average-sized room of approx 4m x 4m.
As there is no long-lasting effect once the smoke has dispersed, we recommend use alongside residual insecticides such as Pest Expert Formula 'C+' Carpet Beetle Spray and Formula 'P' Carpet Beetle Powder.
