Powerful Cluster Fly Powder

Formula ‘P’ Cluster Fly Powder contains a powerful permethrin insecticide which has a fast and long-lasting knockdown effect on cluster flies. 

Formula ‘P’ is ideal for application to roof timbers in lofts, and also to sash window frames and other alighting surfaces and potential points of entry to help maintain cluster fly control for several weeks.   

The powder is supplied in a 'puffer pack' to help with even distribution of the product, and is ven safe for use around electrical equipment and power points where a spray is unsuitable. 


To enable more rapid eradication, we suggest that Formula ‘P’ Cluster Fly Powder is used after fumigating with Formula ‘P’ Foggers or Smoke Bombs, which will flush out all cluster flies present at time of treatment. Formula ‘C’ Cluster Fly Spray can also be used alongside the powder for increased residual protection.


In addition, our bestselling Cluster Fly Kits contain a combination of all our cluster fly killer products along with a professional advice sheet with instructions on how to carry out a successful cluster fly treatment and are better value for money than purchasing the products individually. These Kits now include a 300g Formula 'P' powder instead of the 150g Rentokil Insectrol, providing double the quantity of insecticide!
