Ingredients cypermethrin Review: Actually works and fast! Goodbye spiders - I’m genuinely impressed by the Karlsten Spider Killer spray. I live in an old house that seems to attract spiders every autumn, and this has made a noticeable difference. I sprayed around window frames, door edges, and corners, and within 24 hours I saw far fewer eight-legged visitors. It doesn’t have a strong chemical smell (more like a mild cleaning product), and it dries quickly without leaving residue. I appreciate that it’s effective both indoors and outdoors I even used it in the shed. Tip: spray again every couple of weeks if you live somewhere spider-prone. It’s not cheap, but it does what it promises, and I’d rather pay for peace of mind than wake up to spiders on the wall! Review: Kills spiders, but the bottles stop working - The solution itself is great for killing spiders. Small ones die almost instantly, larger ones will die too but will take longer. It's best use is for creating a protective barrier around window and door entrances. The only problem is that the spray function stops working when there is about 25% left in the bottle, which is very frustrating given the high price. ## Features - Use biocides safely.

Small ones die almost instantly, larger ones will die too but will take longer. It's best use is for creating a protective barrier around window and door entrances. The only problem is that the spray function stops working when there is about 25% left in the bottle, which is very frustrating given the high price. ### ⭐⭐⭐⭐⭐ It kills spiders. What more do you want *by C***Y on 30 November 2024* So for my first rental, I've managed to find myself living on a farm in a converted barn. Here's something to be aware of, for those of you who are either city dwellers or just dumb (like me), spiders really like old wooden buildings with billions of dark nooks and crannies to live in. Both outside and inside. Fun! Despite my spine-chilling dislike of spiders, I generally try to catch them and put them outside. However when the blasted thing manages to cram itself into a nook which is the corner of your window, meaning it's impossible to get in a jar, and you very stupidly put your bed directly under that window because you liked the idea of falling asleep under the stars, you have to figure out other ways of dealing with uninvited, hairy guests. (Not talking about my dad, he at least has the decency not to come over unless he's invited.) So I ordered this. Two spray bottles, one to keep to hand upstairs, and one to keep to hand downstairs. I was pretty skeptical to be honest, but I needed to try something. Anything. By this point I'd dragged my bed away from my window so I could get right up into that nook and blast it with the spray. The spider came out immediately and was clearly not having a good time as it did so, and once it was truly dead and done for, I could get rid of it quite easily. I very thoroughly saturated that nook and I have not had issues in the two years I've lived here since. I've also had the great pleasure of blasting it on spiders outside as well. Spiders seem to love climbing over my garden furniture when I store it away for the winter, so I just absolutely destroy them with the spray and that deals with them nice and quickly. I've seen other reviewers complain about the spray bottle itself not working after a while, but I honestly can't say I've had that experience - I find I need to use so little of the stuff that over two years later I still have both spray bottles on hand. It kills spiders, I can kill them at a distance, it's great. ## Frequently Bought Together - Karlsten Spider Killer Spray x2 | Double Strength Advanced Pest Control Formula for Fast Spider Elimination – Indoor & Outdoor Use - NOPE!
