KarlstenSpider Killer Spray Fogger x 2 Indoor Max Strength killer Destroying all Indoor Spider infestations Fast & Effective Leaving Invisible Residue For 5 Week Protection

Does work,but remember to cover smoke alarms before activating. Or fog will set them all off.

As an arachnophobe, these are an absolute dream and make my loft a less scary place. Simple to use, one hard press of the nozzle and place on a flat surface and leave the area for a couple of hours. One cannister did the job and I can see the evidence that it worked dotted about the loft. The second cannister will be useful to keep control.

killed about 80% of spiders on first go i will use the 2nd tin in 4 weeks pleased with the results

Well, I was in a hurry, and bought this as a direct spray for spiders and other insects - we had just rented a house in the countryside and it turned out to have spiders climbing up the walls every which way!So I mistook what this product was and thought it was a direct spray, not a fumigator. It's probably perfectly clear if you read the small print, but I didn't.So just be aware that this is a product that you spray into the room and leave for few hours and then it will have done its job. That's after you read the small print to be aware exactly how to use it!!!

This spider fogger is fantastic used it once 6 months ago and haven't seen a spider or insect since, highly recommended

I fogged the room a very very large spider was in. Six inch long legs. It escaped through a hole into my built in wardrobe in the bedroom next door, I kept wardrobe doors open and fogged that bedroom assuming the very very large spider would die in the wardrobe. A day later, it is seen in the wardrobe, by the time the neighbour came to collect what I hoped was a dead very very large spider, it had moved. We cleared the wardrobe floor, no sign. So we blocked the hole both sides in both rooms but I feel I will have to fog again. All the small spiders are dead. I am buying spider traps too because this monster has to go.

Not sure it really worked, some dead spiders initially but they soon returned.

Used this for my garage and bought two cause i wanted to make sure the war against the bugs would be won. Set them off and evacuated the area. Upon my return it was evident that i was the victor.Very simple to use just click it in and leave it to do its thing. Its Quality that it acts as a detterent for several weeks and doesnt have a noticable smell. Great price and will purchase again
