The Pest Expert Formula 'P' Cluster Fly Smoke Bombs are a fumigation device for eradicating cluster fly infestations in your home or loft and an essential part of any cluster fly treatment.
The Formula 'P' Fumer is a cluster fly killing smoke bomb which releases an insecticidal (permethrin) smoke and is ideal for getting rid of cluster flies in lofts, roof spaces or other areas of the home.
One smoke bomb will treat a room of approx 6m x 8m (standard ceiling height) and one twinpack should be sufficient to eradicate a cluster fly problem in a standard roof space in a 2-3 bedroom house. To treat a cluster fly infestation in a larger loft area or several rooms add extra Fumers as necessary.
Contain Permethrin at 13.25% w/w.
Directions for use
Check roof spaces for bats or evidence of bats.
Pets/children should be kept out of area at time of treatment and until gas has completely dispersed (2-3 hours). Any fish tanks should be removed and water tanks in lofts should be covered.
Make the area to be fumigated as smoke tight as possible by closing all windows, doors etc.
Place smoke bomb(s) on a heat-resistant surface, for example a biscuit tin lid or an old plate. Handle with care after use as they can become quite hot.
Light the fuse and vacate the room/area. Leave for at least 2-3 hours for the smoke to disperse and then ventilate the room thoroughly.
NB We would recommend wearing a safety mask when using this product.
Use when you notice signs of cluster fly activity. The Pest Expert Formula 'P' Fumer is an essential component in the treatment of a cluster fly infestation and is best used in combination with a residual insecticide such as Pest Expert Formula 'C' Cluster Fly Spray for longer-lasting cluster fly control.
