Karlsten Fly Killer Spray 300ml Aerosol – Insect Killer Spray for Flies, Wasps, Spiders, Ants, Fleas & Silverfish | Fast Acting Indoor & Outdoor Bug Spray

Best flying and crawling bug killer ever

I was really struggling to get rid of a fruit fly infestation from the summer (thanks to bananas?) eventually they were in every room. I’d get one room fly free and then turn around and they’d be in another room so I needed to do something drastic! These flies get absolutely EVERYWHERE! And all it takes is just 1 fly and the next day you’ll have hundreds more. And those hundreds more lay more and more eggs etc etc. (They can lay up to 500 eggs a day (each)!!) so it’s important to get every single last one in order to solve the problem. Anyway, nothing was working. I tried lots of different methods, sticky paper things that you hang from the ceiling, sticky window/wall stickers, natural home made and store bought ‘traps, and regular fly sprays but AGAIN nothing worked, (regular fly sprays don’t get these types of flies because they are too small for it to take effect). So I tried this spray ONCE in every room of the house and it’s killed them all completely. No flies at all now. Not even 1! It does smell awful, but it definitely works! I’d advise you to close all windows, spray the entire room then shut the door and leave the room otherwise the smell will choke you. It is a sort of citrus zesty smell but mixed with the chemicals, the smell will choke you if you remain in the room for too long. But rest assured it does the job once and for all! I also don’t grudge paying the price of £11 because it does kill them ALL. I read the reviews thinking it’ll probably be a waste of money but it definitely isn’t! And I’ve still got half a can left incase they come back next summer.

It's one of the the few sprays that actually seems to kill the flies! It's not exactly fast working but it does the job.

I had a fruit fly infestation so bad I didn’t want to enter that room. Tried fly papers etc, which only caught one. I sprayed this in the room once for a few seconds, left and shut the door. Came back 20-30 minutes later and they’d all gone except one on the wall, which I targeted right away. In the past I’ve tried ordinary fly sprays which never worked. This was incredible! I didn’t notice a smell because I shut the door to the room quickly and left. Totally worth the money for my peace of mind.Amazing!

My family and I have the biggest fear of spiders and can’t stand them in the house. Having tried all kinds of sprays and gadgets to try and rid them in the house, we discovered this on Amazon after the other spray we had sadly ran out. Recently we’ve started finding false black widows around the outside of our property and certainly didn’t want those to multiply. Maybe some would say it’s inhuman to kill them but when you have a fear, you’ll do anything to get rid of them. I was sceptical if this would work but I can say it does. It got rid of the false black widow and your usual house spiders too. The spray isn’t the cheapest but in all honesty if it gets rid of the spiders it’s worth the cost.

Kills flies after a few seconds of exposure (hold in one place), but ineffective against maggots. Smell is not unpleasant.

After finding Solitary Wood Wasps and another unknown insect burrowing into my garden sleepers, I spent a long time trying to find the right thing to treat them. I don’t mind insects in the garden, but these were creating huge piles of sawdust each day, from tunnelling inside the wood. After one application of this spray, all activity has stopped and they have gone. It smells perfectly fine, and I like that it’s an aerosol, so no drips in the garden for the dogs to be interested in. I would buy this again.

Smell is not that strong but i cover nose and mouth as a precaution when using, worked for silver fishes i had, used roughly 4 months ago and no signs of any silver fishes, fingers crossed, sprays well and goes far, effectiveness is long as only used once,
