Review: Fantastic product - highly recommend the spider spray - I can’t rate this product highly enough and am so surprised that there are quite a lot or reviews that say it doesn’t work. We have just moved into a house with a major false widow spider issue in the conservatory. There is a batton that runs along the whole width of the room that you can’t get behind and it appeared to be full of false widows. They would come out to eat on their webs but you could never kill one as they’d just disappear behind the batton. I’d wreck the webs thinking they’d move on but they’d just rebuild overnight. I have a major fear of spiders, especially false widows as they bite, so said to my husband we need to tackle this head on and buy a killer spray! This spray had loads of reviews so thought I’d give this a go although did feel it pricy at £13.99 but I was so desperate to get rid of the spiders I bought it. Well, no more false widows anywhere so as far as I’m concerned it has been worth every penny - all the webs were empty of spiders the following day (I kept checking) and before I cleaned the webs away, the webs had bugs in them which clearly weren’t being eaten so proof to me it had worked as I was seeing the spiders move onto the webs daily to eat previously. We then had one really huge false widow elsewhere (I didn’t know they could get so big) and hubbie sprayed that directly - it didn’t die instantly but it forced it out of its hiding place and whilst I could tell it was dying I killed it with a fly swat just to be on the safe side. The spray worked immediately on smaller ones nearby that I didn’t even know were there. The huge added bonus about this spray however is that it’s also killing flies and wasps that happen to fly into the conservatory - we aren’t spraying them - there’s obviously residue spray in the room from spider gate and that’s killing the flying unwelcome guests too so the statement that it works for up to 6 weeks does appear to be true. If we get a butterfly or bumble bee in we are carefully catching that and releasing it as I do suspect it would kill those too which we don’t want. Anyway, couldn’t be happier with this product. It is a shame it is released as a liquid as we do have to wipe up the excess after spraying - an atomised spray (that comes out like furniture polish spray) would be much better in my opinion and easier to spray in a targeted fashion - the liquid comes out with a very wide spread too and sometimes you just want a direct shot on one bug rather than a sweeping cover. It doesn’t have a nasty or lingering smell and I’m reassured by the safety statements on the listing too - I don’t like the idea of spraying nasty chemicals around my son especially when they appear to kills things for weeks after spraying but it says tested as safe for use in homes so I have to rely on that and was a big part of why I felt happy to try it in the first place. If the false widows didn’t give such nasty bites we’d let them be but they do so we don’t and thanks to this product we are false widow free now! We will continue to spray as a preventative measure every 5-6 weeks as the lasting impact of this spray will help keep them out of the house. Review: It works . - This does not instantly kill spiders . It appears to be a nerve agent that cause muscular contractions. Spiders therefore cannot operate for very long on the sprayed area without being disabled. I also think that it has deterrent properties because this summer there are no spider webs on my balcony outside . This absolutely is a win. This is mid July and I also notice there are nearly zero flies and midges on the balcony. Given that my balcony is outside and also subject to rainfall this chemical still works nonetheless. I have a colony of false widow spiders on the balcony which are seriously dangerous . This chemical has wiped out their operations . If you see a spider on the area you have sprayed it wont last long . I note from the reviews that some people dont realise you have to twist the block at the tip of the nozzle to open the spray . The product details says it lasts 6 weeks and this is what I have found. I use about 30% of the bottle on the first spray and use 2 bottles each summer season . ## 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 ### ⭐⭐⭐⭐⭐ Fantastic product - highly recommend the spider spray *by S***E on 4 July 2026* I can’t rate this product highly enough and am so surprised that there are quite a lot or reviews that say it doesn’t work.

I'm not sure that it worked for the 6 weeks as advertised but I was more than happy with the weeks that it did work for. Even worked outside - you know how you get millions of tiny spiders and millions of webs clinging on to the wooden balustrade on the edge of decking? Well, I had set to with a brush and got rid of all the cobwebs time after time but of course not the spiders. This time, I rid the decking of cobwebs then sprayed it with spider killer and hey presto..... we had a web-free decking for weeks. It's that time of year again when they are all creeping inside so here I am purchasing another bottle (or 2) ## Frequently Bought Together - Karlsten Spider Killer Repellent Spray High Strength Spider Killer- Lasts 6 Weeks On Surfaces Kills All Types of Spiders Ideal for Indoor and Outdoor Use - 500ml HSE Registered 10668 - Pestshield 3 x Spider & Creepy Crawly Insect Killer Spider Spray No More Spiders 200ml New - Zero In Spider Repellent - Indoor Peppermint Oil Spray for Spiders - Non-Toxic, Insect Spray For Home - Suitable for Indoor Use, Lasts up to 2-3 Weeks - 500ml --- ## 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.tn/products/47968534-spider-killer-spray-and-repellent-500ml-indoor-and-outdoor-use](https://www.desertcart.tn/products/47968534-spider-killer-spray-and-repellent-500ml-indoor-and-outdoor-use) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-04*
