The new super-size Pest Expert Formula 'P+' Power Fogger is an extra-large version of the regular Fogger, treating more than double the area, so is perfect for getting rid of cluster flies in large roof spaces and open-plan areas. It can also be used in smaller areas to provide a more powerful, intensive treatment.

The Power Fogger works in a similar way to conventional smoke bombs to fumigate and flush out cluster flies, but as it is an aerosol device it does not need to be lit, so there is no fire risk. Simply push-down on the trigger to release the insecticidal gas, which takes approx 5 minutes to empty. 

As the Power Fogger contains 100% natural active ingredients (pyrethrins) it is completely safe to use yet still has a rapid and powerful knockdown effect on cluster flies.

Each 530ml can has a coverage of 300 cubic m for flies.

Foggers offer no lasting protection once the gas has dispersed, so are best used in combination with a residual insecticide such as Formula 'C' Fly Spray to maintain cluster fly control.
