Review: Kills all known spiders dead on their feet, or in their their webs - Spider Spray, Spider Spray, does whatever the bottle says, Can it kill, spiders dead. yes it can because its a spray (homage to the Simpsons). Kills small ones dead almost immediately, bigger ones take a few sprays, but if you squirt it in the air vents 50 or so will bungay jump out, so make sure you step well back if you have a phobia (which is probably why you brought the spray in the first place. Moving to a house in the country was a big shock, especially when machete weilding spiders run at you. The spray is always on my belt like a spidey John Wayne. Have just brought again.
Review: After a lot of research... - 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.

## Questions & Answers

**Q: Sprayer ceased to work**
A: If you look at the reviews, "failure to spray" has  a frequent walk-on part.  Presumably it is just badly designed or built.  I overcame the problem by cannibalising the squirting mechanism from an almost empty spray of similar design and fit.  Of course, that works so that you can use the contents but doesn't address the design.  I was going to complain until I realised what a common fault it was with the product and concluded that it was no use knocking if there's no-one in!  Best wishes  Fontes

**Q: Can it be sprayed on leylandi**
A: 0To kill spiders on the trees? or to kill the trees?- I think it only does spiders. ( Elsan, camping toilet bleach on the roots, will kill leylandi)

**Q: i sprayed this around the flat very generously, do you think if there was any spiders around they would have come out to run for their lives?**
A: It deff kills spiders , if you spray them directly. Not sure how long it lasts as a deterrent.

**Q: Is it safe to use the moth killer in your bedroom?**
A: Save to use anywhere.

### ⭐⭐⭐⭐⭐ Improve your quality of life and enjoy open windows
*by H***H on 9 June 2023*

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
