It works very well
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 works!
I had a small silver fish problem in my bathroom after the property above flooded. I used this powder around the edges of the bathroom floor and the next morning, there were about 50 dead silver fish and I’ve seen no more since. Great!

Lots of dusting around but still powerful so far
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.

Didn't kill all bugs
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

Effective
Very effective, I tried the sprays first but must say this powder did the trick, in one day I noticed the difference. I had silver fish in bathroom and in a day they were gone, touch wood not seen any since. Powder easy to put down on room edges.

Works as intended
This took a couple of applications, but worked as intended.Killed the silverfish in my kitchen/dining area. I've put in down under the sink, behind the washer and under the stairs as a preventative measure at them coming back. So far, a month after initial application, so good. Recommended.
