Worked well. Don't breath it in by any means. Keeps everything out and kills anything inside the house.doesnt smell great but it's not designed too. Only done effects lasts about 2 weeks. Quite easy to you it's just a spray bottle.

After extensive research on bed bug treatments, I can confidently say that the effectiveness of any product depends on your preparation. Simply spraying a little on your mattress won’t cut it—you need to remove all clothes from cupboards, spray inside them, treat cracks in the floor, the entire mattress, and all parts of the bed frame. However, the bugs can be hiding anywhere and are attracted to the carbon dioxide, so just because you don't see them, doesn't mean they are gone. The pests can hibernate for 6 months without food so it is a pain.This Bed Bug Spray does kill on contact and provides some lasting protection, but if you have a heavy infestation, one bottle won’t be enough. In my case, I had a smaller bedroom with a single bed that was heavily infested, and even with professional-grade treatments like Provecta, C40 WP, and Cimetrol RFU, it still took several applications over multiple visits to fully resolve the issue.While this is a good starting point for minor infestations or preventative treatment, you’ll need several bottles for anything more serious. By the time you buy multiple bottles, you might be better off investing in professional treatment. That’s the main reason I’m giving this 4 stars instead of 5—it works, but it’s pricey for the amount you’ll likely need.Overall, a good product, but be prepared to invest in multiple applications for best results. I also contacted the helpdesk to confirm I could spray this on the mattress and they confirmed, their customer support was very responsive and helpful.

The media could not be loaded. After having 3 spider infestations in our old place, resulting in £100s spent to kill them I always make sure I have minimum 1 of these bad boys at home. I spray every door, window, entry point of the house roughly every 6 weeks and we are 88% spider free. If one escapes in it’s easy to spray and it dies in seconds.This morning the universe tested my very real fear of spiders by sending a beast. This was the thickest and nastiest spider I’ve seen in the U.K. - I ended up pouring the solution over it as I wasn’t sure if it’ll take and the video speaks for it self.It doesn’t smell like anything, I do have a dog so just make sure you read the safety manual.I’m on my 6th bottle tbh. This is a staple in my house and will always be. The only negative is that my last bottle broke the nozzle but it’s not the end of the world

This thing is very effective against spiders. My garden was spider-infested and one-two spray at each (cluster of) spider killed them all under a few minutes. The spiders struggled for a couple of seconds and died. Sorry for them but they were overwhelming...The chemicals inside the bottle work well, but not so much for the spray nozzle. The nozzle worked smoothly, to begin with, but died entirely after only a few presses. The liquid just flows out from the nozzle down my arm into my cloth and I had to shower to clear the toxic skin absorbable chemical. I still feel a bit of burn sensation on the contacted area. Hopefully, the dosage is low enough. Apart from this, the nozzle only has a widespread action, which is good for treating a large area, but it is horrible to target the spider nests and individual spiders. I had to swap it for the one from a spider repellent bottle which uses a far better nozzle that also has a concentrated beam action.All in all, I give it 2 stars for ease to use because the chemical is easy to apply but the nozzle is the worst. 3 for stars for value - it is not a particularly cheap product why use such a horrible nozzle? Overall 3 stars, could have been better but not a bad purchase.

Excellent, I had a major problem with which can only be described as an infestation of large spiders in our garden outhouse and it was causing me a huge problem when sitting in there and also very embarrassing when guests come round and have fly carcasses and weird looking spiders descending on them very unexpectedly whilst enjoying a nice cup of tea or a drink.I don’t like using chemicals or exterminating insects, but they were a real nuisance and after sweeping them out a number of times and trying any number of other activities to try and deter them from coming inside. I had to resort to this. I don’t know why there’s been such a proliferation of spiders, and especially the large weird looking ones, this year?Anyway, I ordered this after researching what options were available and it was delivered promptly the very next day.I swept the outhouse thoroughly and then followed the instructions on the spray, which was to basically spray every nook and cranny carefully and then leave the area and wait.Over the next day and the following week I was surprised by how many spiders came out and basically dropped to the floor immobilised. There’s no sign of any webs or their occupants now and I have reclaimed my comfortable spot in the outhouse and can enjoy reading the newspaper and enjoying my tea without any unwanted insects dropping down upon me. Thanks Amazon, another good job well done.

Does not work on bed bugs, with a direct hit the insects did not die

Great spider killer spray
