Karlsten Spider Killer Fogger Spray – Fast-Acting Spider Killer – One Shot Fogger for Indoor Spiders – Leaves Invisible Residue with 5 Weeks of Protection – 150ML

Does exactly what it says on the tin, my sons van had been parked up on the drive for a few months and became infested with False windows 😩 I put one in the cab and one in the back, they was all dead when I opened it up the next day. Fully recommend.

Before this I rarely went into my garage and stored junk. My brother in law emptied my garage in July - just before spider season, let off the smoke bomb and watched them flea. I refused to be around. We put up shelves and now use it to store suitcases, books, garden furniture, tools and all my garden equipment and I'm in and out regularly. When speder season started I used a water spray with mint and lemongrass to top up what the smoke bomb had done to clear the spiders. My garage connects to my utility room and normally that is wear the spiders enter my house from in their droves!! This spider season only 2 entered (I checked daily). I will be letting off another smoke bomb next summer and following the same routine.

This won’t kill EVERY spider in your home but it’ll get a lot of them. Just FYI though, it’ll set your smoke alarm off when you deploy it.

Very overpriced and didn’t notice it kill any spiders!

Killing things is not my normal approach; I am rather more towards using a spider catcher and putting them outside. But... the conservatory in our new house has proved to be home to rather more life than I could cope with. Large bulbous bodied spiders above my head whilst I'm trying to relax were just not possible to cope with and none of us wanted to be in there. Too many to catch and the hidey-holes and crevices in the structure just too many.Enter Karlsten Spider fogger spray - an unparalleled weapon of mass destruction that dealt with the problem. Set off the night before, by the following morning, a sterile conservatory.Important tip:Remove all furniture, rugs and anything you can from the room before setting it off. I did and I am glad. I didn't really want pesticide residue on the upholstery of my chairs, but more than that it's what happens when you set it off. Within minutes, they began to emerge, staggering about, abseiling down on their horrid webs and expiring suspended in mid air or falling to the floor curled up in the arachnoid foetal position. It was like watching an episode of 24. The following morning - I left the room sealed overnight - I came down to the debris field. Had my furniture been in there, it would have been disgusting, covered in bodies, webs and spiderlings. Having a clear room enabled me to simply sweep, vacuum and reoccupy. Job done.Hopefully I won't need to use another WMD again - I will be periodically applying a spider spray from now on, reviews for which suggest works well at keeping the population low. But if there is ever another excess, Karlsten spider fogger will be back in use. £12.99 for a 150ml aerosol felt like a lot of money but it's one of the best £12.99s ever spent!

Used a can of this in my brick shed ready to install false walls and a new ceiling. There are hundreds of false widows in there. I fogged it out and left it for 2 hours (it's a very small shed apposed to an entire room). I opened the door and let it air out for half an hour and stepped inside, most the spiders hadn't even moved. I decided to poke at one to see if it was dead, it moved absolutely fine, so did a few others. At this point it looks like NONE of the spiders were killed lol. Won't buy again and won't recommend.

"I was driving down the road when I saw a spider hanging in front of my window. I was so scared that I almost crashed my car!Luckily I have amazon and a weekend where the car wasn’t used. Next day delivery brings me the bomb. So it’s not easy to click down and needed the hubby to do this. It’s a difficult task when the bombs going off in your face as you try to click it into place. Anyhoo left in the middle of the car and was fearful I’d come back to some weird residue all over the car but no. Left the car overnight and opened day after to inspect and lo and behold there’s the spider, dead in the passenger seat. Not sure if they all come out of hideyholes like that or if it was luck but anyway knowing it was the right spider and it’s dead makes me feel at ease and in future think I’ll be doing these 6monthly.Overall, I would highly recommend this one use spider killer spray bomb to anyone who is afraid of spiders. It’s definitely worth the investment!and has helped keep me and my son safe, god knows what would have happened if I was on the motorway 🕷️👊

My new home backs onto an allotment and I was getting a lot of HUGE unwanted visitors. My cats were taking care of the problem but leaving their limbs in various places and I once picked up a raisin that wasn’t a raisin… that was enough disembodied spiders for me and so I spoke to Karleston about the best approach with pets in the house :)Their advice was to remove all pets, leave till dry about an hour and then it would be safe. Nobody should lick the can/bottle or drink the solution … sound adviseNo more bodies or legs found for a fair amount of time now, next up is the part of my loft that is still exposed to the elements.Word of advice block up under the door of the room your doing and move humans who don’t like spiders from the area, also.As they come out from everywhere it’s not fun and actually whilst they go quick the big ones don’t go that quick and it’s not very nice to see.But if they invading your home and you can’t deal with it sometimes you just gotta do what ya gotta do.
