Our Pest Expert Formula 'P' Pro Fumer Bed Bug Smoke Bombs contain the same powerful insecticide (permethrin) as the standard Fumer but will treat twice the area. The bed bug killer pro fumers are an integral part of any bed bug treatment, as the insecticidal smoke helps penetrate cracks and crevices where bed bugs are harbouring.

For a faster knockdown and to maintain longer-term bed bug control, Formula 'P' Pro Fumers are best used alongside residual insecticides such as Pest Expert Formula C Bed Bug Killer Spray and Formula 'P' Bed Bug Powder as the smoke has no lasting effect once it has dispersed.

Apply at a rate of one Pro Fumer per 60 cubic metres. 1 Pro Fumer is required to treat a room of approx 4m square (with a standard ceiling height). Once the Fumers have been lit, the room should be closed and left for at least 2-3 hours before re-entering and then ventilated thoroughly upon by opening all windows and doors. Heavy infestations may require more than one treatment.
