Review: Works - It's the only one that actually works!!! I've tried all of the other brands none of them got rid of midgies, but this one works wear a mask folks this is strong stuff. It's a pity it's so expensive.
Review: Does what it says. - Arrived on time and safely packaged, works well on all insects and bugs, only thing is it is a very strong smell, sprayed in morning and still smelt it way in to the evening 12 hours later so i would advise to ventilate room as it doesn't matter how long you leave it for smell to disappear, overall does what it suppose to do, good value for money because it will last a long time.

### ⭐⭐⭐⭐ Dont breathe the air
*by P***A on 6 May 2026*

Works efficiently . Smell was strong but didmt linger. Not sure how effective it is but it would be useful to have more info about whether it kills eggs and all stages ...whether it continues killing them where it has been sprayed , whether it needs to actually be sprayed on the bugs to kill them . I used for carpet beetle and moth infestation and threw out all carpets (wool) underlay and gripper.
