Finally, Peace from Spiders!
This spider powder is an absolute game-changer! I was at my wit's end with spiders, but this product has genuinely delivered on its promise. It's incredibly easy to apply, and within just a day or two, I noticed a dramatic reduction in spider activity. Not only does it seem to keep them away effectively, but any unwelcome guests that do venture near are quickly dealt with. It's given me my home back without the constant fear of eight-legged surprises. Highly, highly recommend if you're battling a spider problem! Only suggestion is that you wear gloves. Obviously its for precaution but definitely worth buying. I usually apply this twice a year to places that ive seen spiders crawling in e.g. inside window, underneath door etc…

Work really well
Usually when i leave my apartment for 3 or 4 months, i come back with a lot of spider, but after using it, i couldn’t see a single one I applied it to every corner in the property (be careful with this as they will start to escape, so be ready) Note that, i’ve been using it since May 2022

Works fast on spiders
As with any insecticide, you have to be careful with it around animals. I put the powder inside the shed and next to the house, in areas dogs and cats and other mammals can't access. I can happily say that this October, my house has been spider free. Every October, houses in England get invaded by house spiders and I've always been freaked out every year because of them. This year, there seem to be more than normal. But the powder has definitely worked.

Use with caution
Only used once and both my child and I got very breathless after the use, it sais its safe but I would wear a mask if using again and open windows.

Amazon description doesn't match bottle label..
We have a issue with false Widow spiders in our conservatory..these can bite and give unpleasant side-effects, there have been a few recorded cases of hospitalisation. So Karlsten Spider Powder, seems to be a good option, as needed something that would get into holes within the roof construction of the Conservatory. The description on Amazon product pages, indicates its safe for humans. However, the label on the bottle has instructions to the contrary. (See images attached). However, very shortly after application, with mask, gloves etc.. a spider was found dead 30mins later. So it does seem to do the trick. I didn’t give a 5 star rating, due to inaccuracy, of the original description, with regard to safety. Also, the bottle needs to be at a fairly upright position to dispense the powder.

Worked a treat
I'd tried various other products before to deal with the spiders living under my decking but nothing seemed to worked, placed this round the perimeter of my decking and sprinkled it all over (the spiders come up between the gaps) and I can say since there's hardly been any since, gona buy more and use it in my shed to kill the ones living in there
