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

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 is the BEST! When we bought our house we noticed a real problem with silverfish in the bathroom. They seriously gross me out. We thought we got rid of them with other products but they started appearing downstairs about a month ago. This stuff has worked wonders. Bought last week. Been using for about 3 days and there are DEAD silverfish everywhere. Wahoo!!!

I have a problem with silverfish and was looking for a product to help me kill their numbers off. This ticks the box and i feel has a preventitive quality to it because it doesn’t instantly kill them like the spray. This means it has a chance to go back to the nest or others and keep up the good work! Since using it and hoovering it up i find dead ones a few days after. I am also using the spray and glue traps too though. Hopefully winning!!

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

Sprayed this powder to get rid of silver fish, tiny little things that can do a lot of damage. Easy to use puffer container and it worked a treat.

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.

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

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!
