This spray is effective and works so.much better when compared to other brands. Bought last year when there was an infestation of ants but have used it this year to prevent them from entering my property, by apraying it around poasible entry points. Highly recommend.

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.

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.

This is very good product but unfortunately the spray applicator is not efficient. The design needs improvement. Otherwise I would give 5 stars

Got rid of them, but i did also steam the carpets aswell. We didn't see one again after that

Don't usually leave a review, however this was so bad, I had to. Kills small spiders, but not the big ones. You need a lot of spray to have any effect. The big ones are just waking fine and going on by there day after they are being sprayed.

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.

Used to kill a false widow who had settled in my house in an eve I could not reach into to remove. Took a good few sprays to eventually kill the spider but worked a treat. Didnt smell great and needed an air after use but well worth the money and will use again if needed.
