Pest Expert Cluster Fly Killer Smoke Bombs 6 x 3.5g - Formula 'P' Fumer Cluster Fly Bomb (HSE approved and tested – professional strength product)

Like many house holds, I suffer the occasional infestation of cluster flies within my loft/attic. It isn't a huge issue as this product is very effective and dispatching the flies and other creepy crawlies. Lighting the fuse is very simple and it ignites well. The smoke emitted isn't the most pleasant of odours so I would recommend using a face covering for protection. Once the smoke bomb is lit, it has an almost immediate effect on the flies and acts very quickly and efficiently. It is prudent to remember that some heat is generated from the product so I find holding with some pliers worms very well. 2 treatments in a large loft area was very effective for me.

Used 2 of the 6 in roof void spaces to good effect. First raid was a slam dunk with hundreds hitting the deck! Easy to use, just follow the clear instructions for success. My guns are now silent until those Fockers return. Air raid warning yellow!

It really works on my loft. It kills all the cluster fly in one go.

These work brilliantly! I’ve used smoke bombs before and they work well, but importantly you need to repeat smoke every few days to make sure you kill most of the flies. Why? Because lots of the flies will escape during the first smoke and they leave a scent in you lift which attracts them back continuously. Buying in a multipack like this meant I could smoke my loft three times (I use three bombs at a time as I have a large loft). Brace yourself for a loft full of dead fly bodies !

Have used before with success. Arrived very quickly. Would have given 5 stars but I ordered a pack of 6 and only received 5.

Save your £18.95 as these didn’t work for us. 5 containers only arrived not 6 as stated. Then the 5 containers we did have didn’t work killing the tiny black flys in our kitchen. We got smoke and it was like something from a 90’s Disco with how much smoke we had in the kitchen, however the flys did not die and a couple of Raid cans did the trick… Quickest way to set the light to £20!

We moved into a new house and discovered lots of cluster flies coming into the bathroom, set this off one night and the next there were loads of dead flies. We are going to set two off in the loft next and fingers crossed this will keep them away. Worked a treat! Will update if they come back.

This year we had an infestation of stink bugs in the motorhome. These things like to overwinter in relatively warm and sheltered places, unfortunately they took a liking to our van. Light these in the van and they all passed away. Remember to stand them on something non-combustible as they get a bit hot as they give off a satisfying plume of smoke. Two were enough for our van. I opened all the internal doors and cupboards and it got all the bugs.
