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. ## Features - Use biocides safely.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly Recommended. *by Q***Y on 29 April 2026* Repellent and Killer of Spiders! ### ⭐⭐⭐⭐ After a lot of research... *by M***. on 18 March 2025* After extensive research on bed bug treatments, I can confidently say that the effectiveness of any product depends on your preparation.

It makes them uncomfortable enough to move so you can catch them and put them outside. Have sprayed under floor vents and potential entrances from outside. Have reduced giant spiders to nothing within 10 days. Before using this spray I had maybe four giant spiders in the house scurrying across the living room floor and kitchen ceiling each night. After spraying entrance zones inc doorways, wall vents and room corners, after a few days the spiders disappeared. I think for large spiders this spray is a huge deterrent rather than something that kills them. I personally do not like killing spiders and before this spray, I tried to remove each spider but this wasn’t effective. Highly recommend spray. Allow a few days for results. ## Frequently Bought Together - Karlsten Bed Bug Killer Spray, 500ml - Fast Acting Bedbug Spray, Strong Bug Killer, Kills on Contact, Bed Bug Spray for Mattress, Bug Repellent, Bed Bug Remover for Indoor and Outdoor Use - Zero In Bed Bug & Dust Mite Killer – Bed Bug Spray for Mattress, Bed Frames & Furnishings - Fast-Acting Aerosol Surface Treatment for Immediate Results - Prevents Allergies - 300ml - Zero In Bed Bug Trap - 5-Pack, Ready-To-Use, Poison-Free Treatment, Bed Bug Detector, Monitors Infestation --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/48276045-karlsten-bed-bug-killer-spray-500ml-fast-acting-spray-strong](https://www.desertcart.pl/products/48276045-karlsten-bed-bug-killer-spray-500ml-fast-acting-spray-strong) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-06-02*
