## 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 & Potassium Chlorate at 12.5-15%.

## Questions & Answers

A: Unfortunately we cannot deliver to France at this time.

**Q: Will it kill drain flies**
A: Yes, provided that the flies are currently in the room you are treating when you sent the smoke bombs going.

**Q: Is anyone use it in flat do you know how to start ?**
A: Magdalena. This product can be used in a dwelling, however the property will need to be closed/sealed up for at least 8 hours. You will then need to open all windows and doors for at least an hour before you go back inside. I would recommend using latex gloves and a surgical face mask.

**Q: Will these kill wasps which have escaped from the nest under the floor into the lounge?**
