Brilliant stuff ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by E***A on 12 July 2026* Love this product. Keeps all small creatures out of my conservatory and house. For 1 to 2 months. Just smell is strong when spraying it. ### ⭐⭐⭐⭐⭐ Very very effective! *by B***E on 11 July 2026* Highly recommend! Very effective for killing spiders! Great value for money! Very strong smell when spraying and lasts a good length of time! We buy this product time and time again! Highly recommend investing in a spray bottle to use this product though! ### ⭐⭐⭐⭐⭐ 3rd year running ... *by P***O on 9 June 2026* I first came about this product when I payed over £150 to get pest controllers specialising specifically in spiders, to come make my home spiderproof. They sprayed some cloudy chemical that seemed to work, though not along as they had claimed (6 months). After a few visits by them, they recommended this product after the second summer. I have used it since 2024 and it had worked a treat. I saw 0 spiders, I mean ZERO throughout the year of 2024, two or three in 2025 (months in spring before I used the spray,as I dont use it through the winter months), and so far only once this year (again in early March). I recommend it and confident i will see very little of the monsters again this year. ## Frequently Bought Together - Karlsten Spider Killer 5 Litre - Fast and Effective Spider Killer | Lasts 6 Weeks On Surfaces | Kills All Types of Spiders | Ideal for Indoor and Outdoor Use - Spear & Jackson 5LPAPS 5 Litre Pump Action Pressure Sprayer - Spear & Jackson 2LPAPS 2L Pump Action Pressure Sprayer, WHITE AND RED --- ## 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.dk/products/326236023-spider-killer-5-litre-fast-and-effective-spider-killer-lasts](https://www.desertcart.dk/products/326236023-spider-killer-5-litre-fast-and-effective-spider-killer-lasts) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-08-30*
