Karlsten Spider Killer Indoor/Outdoor Ultra Strong 10 Litres With 1.2 Metre Extension hose Ready To Use

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.

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!

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.

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).

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

…..I’m so terrified of spiders. I use all sorts of everything to try and prevent them, and, I’m so sorry, to also permanently stop them in their tracks. Approximately every 4 weeks, I spray my homemade peppermint oil spray all over my soft furniture, including cushions, and I wipe it around all windows and doors. I place peppermint soaked cotton wool balls in drawers and cupboards. I have done this for years. It is time consuming etc, but well worth it. Peppermint doesn’t stop them permanently though, once a spider (or spiders) are in, they are blinking well, in. This is when this spray then plays its part. Again, every 3 to four weeks, I spray this spray all around my skirting boards / edges of my rooms, all over my home. Hoovering first, and then leaving any hoovering for at least 3 days, after spraying. I spray it using a 5L garden sprayer container - makes the job so much easier and quicker than a handheld spray bottle. My local area also experiences silverfish often. I am not at all scared of silverfish, however they are not nice to have in your home, even though harmless. I find this spray works on both spiders and silverfish. My evidence for that is that I find expired spiders and silverfish around my home occasionally - usually near the skirting board. Whenever I come across a live spider or silverfish - which thankfully isn’t often - they are extremely slow, really slow, strolling (not running at all) across wherever it is they are. It is clear to me on these occasions that they have walked across this spray and are slowly expiring (I’m so sorry) as a result. I also use those electric fly swatter rackets things (1 in every room, including my car) and use this on any live spider or silverfish that I do come across. This method is instant, I find the rackets work better on spiders than they do on flies lol. I have been using this spray for around 4 or so years now. I always have a container of it at the ready I can genuinely and thoroughly recommend it.

As you can see in the video . I was following that big hairy @$$ spider and because i was panicking i might lose it and my daughter get heart attack i just keep spray on it . It took about 2 or 3 minutes to stop moving finally but it killed the little one quicker. In other hand amount i spray on that spider could kill elephant 🐘 🤣🤣😜. I think probably one spray would have been enough and would take same time as that many. So now at least we know it works there is ni smell and i just put it in empty glass cleaner bottle after i washed it probably and let it dry. So far like a good quality because im sure you guys know must this spider repellent or killer don't work. Value for money and easy to spray so gar very happy with performance lets see how long stay active on the floor. Update : it moved around 1 meter before almost stop moving in the picture
