Pest Expert Formula ‘P’ Silverfish Killer Powder XL 300g pack size (HSE approved and tested - professional strength product)

We did have an issue with silverfish turning up in several rooms: sticky moth traps placed on the floor caught them in large quantities. I then thought to give this power a try. While we were on holidays, I distributed the powder in corners and near walls. On return, we removed the powder again. I didn't see any dead silverfish lying around. However, the moth traps now are free of them and I have not yet seen any at night again, so I feel they improved the situation a lot.

I bought this to kill silver fish. Nothing else worked, the pesticide sprays were absolutely useless, but because the powder remains on the surface it means that the bugs are constantly being killed by it. The only problem is it's so powerful that it kills all insects that come into contact with it, now I keep finding dead spiders and the odd wood louse! Terrible way to kill a living thing but at the end of the day, when the critters won't leave your home, there's sadly no other option. 10/10 for effectiveness and value for money.

This product has only one hole and you have to shake it a lot for this powder. I have powder on my skirting board and below it. I have used it start of December in the bathroom and store cupboard. Have seen only a few silverfish in the beginning and also I had to reapply once in the bathroom because of the moist condition as I have seen two silverfish. I am pleased that I am not seeing any silverfish so far but I would prefer to buy the spray instead next time.

Works to get rid of bed bugs.

Have a silver fish problem. Applied the stuff to infested areas in my house, now its been just over 3 weeks and haven't seen the little buggers since. Very happy with this product.

Super easy to use, I used it around the corners of my room and after 2 weeks of vacuuming dead silverfish, they stopped popping out at all, it's definitely been a while since I used it and haven't seen any since. The lid does come off easily so be wary of it when using it or you'll end up with a mountain of powder on your floor

Worked. Not right away had to put it down every night for a around a week but now all gone. Found a few dead ones each morning until eventually there was no silver fish left. Definitely killed them all as I checked a week later by getting up at midnight and turning lights on in bathroom. Non. Thank god. Horrible buggars

Didn’t work for silverfish
