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

Ok, so I'm not going to be silly enough to take macro pictures of dead spiders, because: arachnophobes. You just have to trust me. This works. Grab a couple of empty spray bottles, fill them with this stuff and spray all around your doors and windows every once in a while (maybe, one a week, or fortnight). Initially, you will see lots of invisible spiders freak out and scatter. This is initially horrifying, but ultimately a good sign. They'll die pretty fast -- even the ones the size of small mice -- which is good. But here's what's even better: preventing them. Somehow, the spiders just know your home is a death-zone, and don't return. I bought this stuff after killing 16 spiders in the home in one week. Living in the country, we had a crazy amount. Now, after this stuff, I've manually sprayed about 2 of them this entire summer. They're just nowhere - well, nowhere near us.There is a slight odour, but we don't find it nasty at all. We have a cat, and even the cat doesn't bother with the smell -- which demonstrates this stuff isn't harmful to them (unless maybe you spray them directly in the face -- I haven't tried).Overall, the price does seem a bit high, but it's 5 litres of the stuff, and works out economical vs. buying cans or bottles.Bottom line: Karlsten Spider Killer works. Don't be fooled into buying peppermint, natural citrus alternatives, or weird ultrasonic emitters; they're largely ineffective (in my own experience, and demonstrated by numerous YouTube videos).You want rid of spiders, this is what you get.

Does the job and works immediately. Noticeable absence of spiders and dust gathering webs. Seemed to work better than other brands purchased previously.

Does what it needs to keeps that out for good 2 weeks. Is very very strong. You dont wanna breath in the same room for about 4 to 6 hours minimum. Great value for money as it does get rid of creepy crawlers. Does not however kills rats (yes i tried).

I was very sceptical about this product. I would have been out in the garden daily brushing away spider webs off the gazebo etc literally a new web would be in the same place the very next day, and having tried a couple of other things after a little googling and not working I thought I'd give something like this a try. I read the reviews which are generally positive and I figured worth a try, you'll never please everyone. I wouldn't say I was tormented by the webs just more of an irritation and very conscious of them if have friends or family around. First time treating I used a garden sprayer but was going through the contents too quickly so switched to pouring some into a spray bottle and narrowing the target areas. Been a couple of weeks since I got the product and I'm amazed at how well it works. If it continues keeping them away this is will an annual purchase for that peace of mind. I've already recommended it to people.

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!

This spray did not stop the red spider ants from coming back, the ant s came back within 30 minutes to all surfaces😩😩

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.

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.
