NOPE! CP Silverfish Killer Spray - 500ml - Spray Long-Lasting, Fast Acting for Indoor and Outdoor use

The spray surprised me with how effective it is. I’d been noticing silverfish in my bathroom and storage closet, and this spray made a difference almost immediately. Within a day or two, I saw far fewer of them, and after a week, they were practically gone. The spray is easy to apply, doesn’t have an overpowering smell, and dries quickly without leaving stains. I also appreciate that the results last I only need to reapply occasionally as a preventative measure. If you’re dealing with silverfish indoors, this is definitely worth trying. Effective, simple to use, and genuinely long-lasting. Highly recommended!

Definitely kills silverfish, found some dead ones after using this.

This works, a few sprays around the surface above my boiler (critters seems to like warmth) and I haven't seen any since. BUT... (and 1 star off for this) I tried and failed to read the small print at the time (far too small) but now with a magnifying glass I have read them... it doesn't seem to mention wearing or a mask or wearing gloves. I felt unwell for a couple of hours after use with my breathing and I felt a little nauseous. The active ingredients seem to be of industrial strength and suitable for use by professionals too (says this on the small print). So it's great stuff and really strong, BUT I recommend: | 1. Opening windows | 2. Wearing a mask | 3. Wearing gloves |

If you have a Silverfish problem get this ! We had been battling them for months and things were getting to the stage where every bathroom and the kitchen was affected, we would turn the lights on and these prehistoric looking pests were zipping around. We tried “natural” sprays and diatomaceous earth but this does very little. The only way we found to really impact the population was to go full genocidal on them using this product. Spray around the skirtings of all rooms where we saw them. Sprayed into cracks, under bath panels, behind kitchen kick boards, under kitchen cabinets, in-fact everywhere we could all round the house. Within two days dead bodies started appearing, sightings of wrigglers dropped to zero. We will reapply every three weeks for the next few months to try to kill the population at every part of the life cycle.

Fantastic and effective, finally something to get rid of the silverfish that works!

Great product, haven't seen a silverfish since I've sprayed. Doesn't leave marks nor stain carpets

Sprayed this all around my home and the next morning I found 2 dead sliver fish which I was surprised about. Unfortunately I am still seeing a few live ones walking on my walls. So hopefully after a few more sprays around my home it will do the job at killing these horrible things.

Works really well, I applied it in my house to get rid of silverfish, which had appeared almost daily in the bath, I sprayed it everywhere, and amazingly, they are no more. It seems to last for a long time before reapplying too. As a bonus it also seems to deal with spiders, and worked when a large spider ran across my living room floor (I am not afraid of spiders but this one was HUGE and did make me panic... ) thanks to this the spider was no more. It has a feint smell when applying but soon disappears.
