Very efficient
Instantly effective. A couple of points; bed-bugs smell! It's an acrid, sour odour that makes you want to take a shower. But it's not you, its them. Entering the bedroom a few hours after spraying, everything was sweet and clean again — and, sure enough, no bites last night.Other point is, if the spray won't work for you, try twisting the nozzle from 'off' to 'on'.

Doesn’t work on carpet, but does on Beds
I brought this one Bed bug killer as well as they bed bug bombs, took advice from a Friend, too buy same product, had too do two rooms my bedroom which has carpet an Children’s room got hard wooden flooring, it’s seems to have worked for the children room, it’s still on going for me, so glad that the girls gets no bites, the two bottles I received were smaller than expected, I would recommend to use this if you have wooden flooring, can also be use on furniture without it staining, the smell is okay not too strong, Am thinking of ripping up my carpet.....

Works well. Cap could be better
The spray pump cap actually stops working after few squirts of liquid. Not sure why but there is a residue blocking the pipe which appears after a day or two. Maybe the pipe getting corroded.

Spray broke
The spray stopped working after only a few sprays. Nothing I did seemed to make any difference. I can’t tell if the product is effective because I haven’t been able to use it much as yet. Can’t be bothered to send it back as I really want to use the product and stop the bugs as soon as possible, so I’ve had to decant some into another spray bottle. This isn’t good and for the price I’d expect better.

Bedbug killer
I buy this product to spray around the bed mattress and as a preventative measure, I have never had bedbugs in my house, but because I own a bed and breakfast. I want to make sure that my beautiful mattresses stay beautiful and uninhabited by unwonted guests. It does not have a nasty smell. It’s very easy to use and keeps my bedrooms safe for other people And my family

Effective and Easy to Use!
This bed bug spray works well and is easy to apply. Does what is says on the tin! The spray bottle is simple to use, and it covers a good area without much effort. It gives peace of mind knowing it kills on contact and can be used on mattresses and around the home.It feels like a strong and reliable product, and it’s good to have on hand if needed. The 500ml size is also decent and lasts a while.Overall, a solid product that does what it promises and is easy to use.
