## Overview

Pest Expert’s Formula 'P' Cluster Fly Smoke Bombs deliver professional-strength permethrin fumigation that rapidly eradicates cluster flies in large indoor areas.

## Description

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.

Review: Ideal for Cluster flys - We’ve been suffering from Cluster flys in our loft and Three of these did the job in just a few hours. Great products and very easy to use.
Review: MOTHS So far so good - I have bought these twice, once because I only did two rooms, the second time to hit every room at the same time. They work well. If I get moths again, these are my first port of call.

### ⭐⭐⭐ flea Killer
*by B***S on 2 August 2021*

It is really difficult to kill fruit flies. Look up the subject on the web and find plenty of different recipes. All perfectly useless, so this smoke bomb is the best yet. Some of the fleas will poke a finger at you, but most are happy to die. The smell from the bombs disappear quickly. So if you hate fruit flies, then this is the best way of inning them
