Pest Expert Cluster Fly Killer Smoke Bomb 6 x 11g – Loft & Home Treatment | Professional Strength for Amateur Use – Full Loft and Home Fumigation, Fast Acting Fly Killer

Works well.

Tried loads of different methods over the years but this wiped them out. One pod in each room and we haven’t seen a moth in weeks.

I used two of these in quite a large loft space. All cluster flies were either killed for forced to leave. I use once a year in September and the flies are gone until the following summer.

This worked like magic. I can't thank the manufacturer enough. I was mortified with hundreds of cluster flies but as I suffer from COPD I was struggling to breathe using household fly spray. This smoke bomb eradicated them all on first use. I was able to light the fuse and close the bedroom door so as not to breathe in the smoke. Not a single fly left the following morning or since. I can't recommend this product highly enough. I'm so grateful. Thank you.

I have bought this product multiple times to treat cluster fly issues in various loft spaces and out-buildings on a farm. The product is easy to light, with a good wick. It does emit a large amount of smoke, so be aware of smoke alarms and be careful not to inhale. It can permeate through down-lights as mentioned in other reviews, and can impact any fabric in a room. I'd agree that the product has low residual odour but still persists for several days. You need a heat-proof base to go underneath the bomb as it does get hot as it burns. Expect to need multiple treatments, with 2x per year a good recommendation. Very effective product and would purchase again.

This is the second time I have bought this product. The first time they worked perfectly, the second time (a new purchase) they didn’t work they smoke for less than 20 seconds so you have to use more. the fact its supposed to have 11g is rubbish. I used it in a 2.5 x 3.5 space and had to use 3 of them

I must say this was great. Opened my lounge door one morning and it was absolutely over run with big bottle flies. It was actually scary to go in, there were so many and it stunk! Bought these based on previous reviews on amazon. Followed the instructions but did use 4 in the room because I thought the size was small. Sealed the door with plastic sheeting after starting them and stayed out for more than the 24 hours. Smoke had all gone when I opened it up and the carpet looked black with all the dead flies on it! Disgusting topic I know and I was very shocked it happened in my house! The culprit- a poor bird had fallen down through the chimney breast which was open at the time due to renovation. Haven’t had any more since so very happy with the result of this product.

Quite expensive, and the instructions are printed so ridiculously small, when you're making so much profit, don't try and save by making the instructions unreadable. They do work though.
