Product information

The Pest Expert Formula ‘P’ Pro Smoke Bomb is a fast-acting fumigation device that will kill all cluster flies exposed to the airspace. The smoke bomb is an essential step in achieving total cluster fly eradication. Once lit, the fumer will release maximum strength Permethrin into the airspace that will kill adult cluster flies.The smoke bomb is non-residual, so carpets and furnishings will not be damaged during or after fumigation.

One of the Cluster Fly Smoke Bombs will cover larger spaces such as lofts and open-plan living areas. However, for a more intense treatment or a larger sized room, add extra twin packs as needed.

One fumer contains Permethrin at 13.25% w/w.

Directions for use

Ensure the room is as airtight as possible by closing all doors and windows.

Place the Smoke bombs on a heatproof surface, such as a plate or baking tray. Be sure to take care after use as they can become hot post-fumigation.

Light the touch paper and leave the area immediately. Leave to fumigate for 2-3 hours so the fumes have time to disperse throughout the room, then thoroughly ventilate for 1-2 hours.

NB We would recommend wearing a safety mask when using this product.


When treating cluster fly, it is always recommended to use a combination of insecticides to ensure full eradication is achieved. The Formula ‘P’ Cluster Fly Smoke Bombs are best used alongside both the Pest Expert Formula ‘P’ Powder and Pest Expert Formula ‘C’ Spray.
