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! Review: Great product - Fantastic and effective, finally something to get rid of the silverfish that works! ## Features - Use biocides safely.

I don't have issues with asthma or chest so notice if use this product get tight chest so don't apply near where sleep and keep windows open. Had it sprayed up attic and within 2hrs got 1st one as pictured. It works for few weeks as long as don't wipe away. It says to use on non porous surface, so not sure how long will last on boards up attic before needing to reapply. Bathroom tiles in corners had dead ones weeks after applied as long as don't mop and clean it off ## Frequently Bought Together - NOPE!
