I was skeptical about this but we have a barn which had a small wasps nest inside. I didn't really fancy smacking it what have you, so I tried these canisters of pure joy.They are a lot smaller than I'd hoped, then again, we probably didn't want loads of the spray going everywhere. We balanced 2 on a brace across the roof space, pulled the little trigger and bosh, room fills up with fog like a night with Matthew Kelly on Stars in their eyes. - can empties in about a minute.We legged it and shut the door, returned in about an hour to find that the wasps had completely gone. No idea where they went, but after tapping down the nest, we are now jasper free!

We set all four off in the loft and left them for most of the day. When we went into the loft to retrieve them, we couldn’t see many bugs… either we set this off on a day when the bugs left or it’s not very effective

Worked well
