Pest Expert Formula ‘P’ Cluster Fly Powder is a powerful permethrin dust (0.5% w/w) which kills cluster flies.
Supplied in an easy-to-use puffer pack to enable precise application to alighting surfaces including window frames, roof timbers and areas where a water based spray is not feasible.
Formula 'P' Cluster Fly Powder should only be used in areas inaccessible to pets and where it can remain undisturbed. Unlike sprays, it can be used safely around plug sockets and electrical devices.
For best results we recommend use alongside Pest Expert Formula 'C+' Cluster Fly Spray as the combination of different active ingredients enables a faster and more effective knockdown of cluster fly infestations.
