Formula ‘P+’ Cluster Fly Killer Fogger Treatment 4 x 150ml – Maximum Strength Fly Bombs for Fast-Acting Effective Control, Professional Strength for Approved Amateur Use

These bombs work great.Good value for money easy instructions.

These do exactly what they say on the tin - great product

Not sure what happened but first time very loft full of flies. Tried traps, hand held sprays ALL failed. 2 of these cans, 12 hours later when opened NOT ONE Left AMAZING PRODUCT

I've used these and the larger version made by the same company. They do kill some of the cluster flies in our loft as can be seen from the dead bodies, but quite a lot seem to survive.

Great product being struggling with a cluster of flies and must say the product is a tiny volume but packs a hell of a punch…extremely satisfied well worth the money….!

We had a swarm of cluster flies. Couldn’t get rid of them but this product cracked it!

Good product but the volume is far less than my previous purchases ( I thought I was purchasing the large size ) Not sure whether there will be sufficient “power” to do the job

Unfortunately made the mistake of ordering 4 cans of this and havent saw any improvement. The seller advised to purchase some residual spray of the same brand, but I'm reluctant to waste anymore money. Previously purchased the Johnsons brand fogger and this worked great. It also leaves a residue for up to 7mths so no follow-up spray required.
