Pest Expert Cluster Fly Killer Smoke Bombs 4 x 3.5g - Formula 'P' Fumer Cluster Fly Bomb (HSE approved and tested – professional strength product)

Excellent product. Does a good job

Fingers crossed, by the time we get back from holiday, all the cluster flies should very gone. Seemed to work well.

One was faulty but when they do work, they work!

Paid £80 last year for cluster fly treatment, that was with £10 off as my neighbour had the treatment too. I was told they could come back each year which they did, fortunately not as many. I set two smoke bombs off on a cooking tray in the loft and went out. When I came back I just had a quick Look and couldn’t see any of the flies, want to leave in 24 hours before going in properly but I’d say it’s been very effective. I wasn’t sure what to expect but the smoke just rises steadily and fills the air, no sparks or anything crazy. Bit like incense smoke but more intense. I’d say it’s a brilliant product as it’s cost around £7.50 to treat. You get a piece of paper included which tells you how much to use for the size of the area that needs treating and also for what pest you are trying to exterminate

A total waste of money. Bought 4 and every single one took alight, burnt through the centre leaving the actual poison product around the rim. They burnt down to the bottom within a minute and a half and let off very little smoke in the process. Bear in mind also, my flat is tiny and I used 4! Total waste of money. I really cannot recommend this product and, for the price paid, feel totally ripped off to be honest. Cannot show pictures as thrown away before asked to submit my review, which is a real shame.

It seemed to do the job until more moths appeared almost two weeks later. It does say that if you have a heavy infestation then to do again 5 days later. I wouldn't have said I had a heavy infestation so I didn't do again 5 days later particularly as I'd used a spray too Be warned.....it stinks and your room, and everything in it will smell for a few days. Even my air purifier didn't help much

Seemed to have done the job No more cluster flies in attic

Nice
