Pest Expert Formula 'P' Cluster Fly Smoke Bombs (Twin Pack)

Our Price: £6.95

Cluster Fly Smoke Bombs - Twin Pack

Pest Expert Formula 'P' Fumer Cluster Fly Smoke Bombs (or smoke generators) are the perfect solution for getting rid of cluster flies in lofts and roofspaces. They are an excellent fly killer, and an integral part of any fly treatment programme, providing a fast and highly effective method of killing flies and many other insect pests.

Apply at a rate of one smoke bomb per 120 cubic metres. One smoke bomb will typically treat a room of approx 6m x 8m (assuming a standard ceiling height), so two would be required to treat a standard loft space. Once lit, the room/loft should be closed and left for at least 2-3 hours and then ventilated thoroughly upon reentering. Heavy infestations may require more than one treatment.

As smoke bombs have no residual value once the smoke disperses, to help maintain successful fly control they are best used in combination with Formula 'C' Fly Spray.

Unbeatable Value! Stock up and pay only £2.72 per smoke bomb, when ordering 11 or more twinpacks.

Fast delivery. Excellent product, got rid of Cluster fly problem I had for years.

James Elliott-Hampshire-5 Stars

Problem with cluster flies. Used the Pest Expert Formula P Cluster Fly Super Fumer Smoke Bomb 11g. Easy to use. Totally effective. I had underestimated the problem - after seeing only a few flies - but once I used the product it was clear the problem was much bigger. Unfortunately, it does appear to be an annual problem now, but one single use of this product and it prevents it being one for another year. Definitely recommend. Quick to post too.

We've had a cluster fly infestation for a while. The products from pest control supermarket are great. I've just used the smoke bombs for cluster flies, easy and safe to use. I rang up before buying for advice and they were really helpful and explained all the possible solutions clearly. The cluster flies are now all gone. Not a single one of the blighters left. I've also bought a few other products to make sure they don't come back. Thanks pest control supermarket.

David-Turners Hill-5 Stars

Very prompt delivery, excellent products.

We had a problem with cluster flies, visited the website. It said use smoke bombs once the first frost has passed when the flies will be in the roof voids. We did. There must have been tens of thousands and we killed the lot for £40. Much cheaper than pest control companies. We repeat once a year to prevent recurrence. works like a dream - no more flies !!
