It’s been 2 months and applied first 2-3 days, since then no silverfish. It’s really effective and no odour as it says on the packaging. Review: Fast acting and effective! - 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! ## Features - Use biocides safely.

It’s been 2 months and applied first 2-3 days, since then no silverfish. It’s really effective and no odour as it says on the packaging. ### ⭐⭐⭐⭐⭐ Fast acting and effective! *by M***E on 1 December 2025* The spray surprised me with how effective it is.

BUT... *by S***X on 6 August 2025* 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 | ## Frequently Bought Together - NOPE!
