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

Works to get rid of bed bugs.

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.

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.

The product did not kill all bugs, after a few days of using found new live ones. So I used the powder again and still found new ones alive. Only used for a small studio dissapointed it didn't kill all of them knowing there still alive in the house is a horrible feeling

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 is the best pest control for silver fish or ants. One thing to remember the top is loose so keep a finger on it when putting it where needed or you find it flys off not exactly a light dusting ha ha.

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

Don't actually think this goes anything whatsoever haven't found any dead silverfish near by and still seeing them alive everywhere
