Product Information
The Pest Expert Formula 'P' Fogger is a cluster fly killing fumigation device which releases an insecticidal (permethrin) gas that will flush out cluster flies in lofts, roof spaces or other areas of the home. 

The Fogger works in the same way as a traditional smoke bomb; however, as it is an aerosol (ULV) and requires no naked flame, it will not trigger smoke alarms and poses no fire hazard, so is perfectly safe to activate in lofts with roof insulation etc.

One Fogger will treat an area of 150m3, which is the size of 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 Foggers as necessary.

Contains 0.2% w/w pyrethrins.

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.

Close any windows and doors and place Fogger in the centre of the area to be treated.

Remove cap and tear off plastic strip. Push down on trigger and twist slightly to lock in place. The contents will take 90 seconds to be dispersed.

Vacate area for 2-3 hours and then ventilate upon return.

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

Use when you notice signs of cluster fly activity. The Formula 'P' Fogger 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.  For value for money, please see our Cluster Fly Control Kits which contain a range of our best cluster fly treatment products.

P-Fogger does the job

Have used P-Fogger cans in previous years to clear my loft of troublesome cluster flies once a month each autumn and winter, and also woodworm in my storage shed which contains valuable hardwood timber during the spring/early summer. Easy to use, and seems effective. I very much appreciate the prompt delivery, plus the addition of a couple of pairs of blue nitrile gloves and face-mask with each consignment for safety. Can fully recommend this product to anyone who has trouble with persistent flying pests such as flies, woodworm or wasps during the respective nuisance periods. Very easy to use
