## Overview

Pest Expert Formula ‘P+’ Cluster Fly Killer Fogger is a professional-strength aerosol treatment containing 0.2% pyrethrins designed for rapid, whole-room fumigation of cluster flies. Covering up to 150m³ per can, it activates without a naked flame, ensuring safer use in insulated or sensitive areas. The fogger leaves no stains or strong odors, making it ideal for both residential and commercial environments seeking fast, effective fly control.

## Description

The Pest Expert Formula 'P' Cluster Fly Killing Fogger is a fast-acting aerosol device containing a powerful insecticide which kills cluster flies in lofts and roof spaces. 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.
