Karlsten Spider Killer Spray x2 | Double Strength Advanced Pest Control Formula for Fast Spider Elimination – Indoor & Outdoor Use

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.

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.

After using these all around windows and doors, we’ve not seen any spiders for months

Okay, so it kills spiders. HOWEVER and this is a big however.. to use this product its a complete farce!The spray just doesn’t spray and even when you think you got a working one. It WILL eventually stop working. Initially I though fine, I’ll just pour into another spray container - but even then I fond it doesn’t always spray well like other liquids would. It’s baffling! It really stresses me out because when it stops working you’re pressing and pressing (literally hurting my hand). Then I think shall I pour it, but you possibly couldn’t. You’d go broke doing that. I really don’t like purchasing it at this point however I have a phobia of spiders and that’s going to supersede and inconvenient/stress using this product.They need to get rid of these bottles and start again (or maybe it’s just the formula that doesn’t work well being sprayed if that’s the case will just have to continue to struggle).

Quite a few negative comments, don't know why, this stuff is good. We spent all Summer trying to dissuade spiders from entering our conservatory. Spent a fortune on Peppermint spray, citronella diffusers and candles and nothing worked. We must have taken over 200 spiders to the bottom of our garden. Enough is enough, don't want to kill them, but they won't listen. One spray the spider stops running, curls up and goes to spidey heaven. It's not instant but the spider won't run off. Recommended.

Holy Moley!!! This spider spray works.... I sprayed all the wall edges and behind the sofas and left it.I went to dust and Hoover behind them this weekend and OMG I found FOUR HUGE dead spiders!! I sprayed two weeks ago. Freaked the hell out of me but so happy they're dead rather than me screaming the house down and sprinting faster than Usain... I don't know how I'm going to be able to scoop them up to get rid but I swear it was not what I was expecting to find when I came to dusting.I'm going to be bankrupt though. Now I want to buy all the stock and coat every wall and floor in the house! 😊For this arachnaphobic, it does help. I swear I have NO idea where they come from through?? I have no gaps in edgings or window. Everything is sealed well... welp.

Although the contents in the bottle are great - both of the spray stopped working. This is very annoying!! I was using the first spray for a few minutes when it stopped working, I then put the other spray gun onto the bottle and the exact same thing happened again. It has left me with the only alternative to pour the liquid, which is no help whatsoever. I shall look for a better alternative. This is a shame as I believe this would have been perfect otherwise.

It does exactly what it says, kills them more or less straight away. Does make you sneeze though but a mask stops that. The only drawback to this stuff? You spray one of the little squatters and it shouts its mates. I sprayed one spider and ended up with five, it scooted them out of hiding. Must admit its brill, but maybe for arachnophobics like me, heavy boots and spare pants could be added to the package. Would definately recomend. And doesnt smell either.
