Pest Expert Formula 'P' Cluster Fly Powder is a highly effective cluster fly killer with a long-lasting residual for maintaining cluster fly control.
Formula 'P' Cluster Fly Powder is a contact dust from Pest Expert containing the broad spectrum insecticide Permethrin, a highly effective cluster fly killer and an important part of any comprehensive cluster fly treatment.
Directions for use
Supplied in an easy-to-use puffer pack, Formula 'P' should be applied to roof timbers and other alighting surfaces and any obvious entry points or harbourages.
Ideal for applying to areas where a spray may not be suitable, e.g. close to electrical appliances or power points.
To achieve a more rapid knockdown of cluster flies, we would recommend use in conjunction with our Pest Expert Formula 'C' Cluster Fly Killer Spray and Formula 'P' Foggers or Smoke Bombs to flush out the initial cluster fly infestation.
For value for money, please see our Cluster Fly Control Kits which contain a range of our best cluster fly killer products, now including Formula 'P' Powder.
NB Contains double the quantity of Rentokil Insectrol Powder!
