More Details

Pest Expert Formula 'P' Pro Fumers are cluster fly smoke bombs for fumigating cluster fly infestations. Once lit, the Pro Fumer releases a smoke which is ideal for getting rid of cluster flies in lofts, roof spaces or other areas of the home.

The Pro Fumer is twice the size of a standard smoke bomb, and so contains double the amount of the powerful insecticide permethrin (13.25% w/w).

Each 7g Super Fumer will treat an area of approx 240 cubic m, so you will need to use 1 Fumers to treat a standard roof space in a 2-3 bedroom house.

As there is no long-lasting effect once the smoke has dispersed, we recommend use alongside residual insecticides such as Pest Expert Formula 'C+' Cluster Fly Spray and Formula 'P' Cluster Fly Powder.

How To Use Formula P Pro Fumer Carpet Beetle Smoke Bomb

  1. Consider how many fumers you need for the room to be treated. Heavy infestations may require more than one application.
  2. Clear people and animals including fish from the room before use.
  3. Place canister(s) spaced out on the floor surface on a heat resistant surface e.g. a plate on top of a sheet of aluminium foil 50cm x 50cm. IMPORTANT: THIS PRODUCT MAY EMIT SOME SPARKS UPON IGNITION. CAUTION MUST BE TAKEN WHEN LIGHTING THE PRODUCT.
  4. Make the area to be fumigated as smoke tight as possible by closing all windows etc.
  5. Open canister(s) and light the fuse on the canister furthest from your exit point first, then light the next fumer and move towards your exit point. Close the door on exit, it is not necessary to seal the door with tape.
  6. Leave for at least 2 hours but preferably overnight and then ventilate the room thoroughly.
  7. For severe infestations fumigate 3 times at 5 to 7 day intervals.

Apply at a rate of one generator per:

  • 240m3 for flying insects
