Silverfish Elimination Kit: Effective Pest Control with 24 Silverfish Paks in 1 Box | Eco-Friendly Formula | Premium USA Supply Gloves for Safe Eradication | USA Supply Pest ID Card

This does the trick. You need to use many of them- I typically use 2.5 boxes throughout my house (you can’t put just one in a large room and expect them to work), and I write the approximate date of next replacement on each pack before walking around the house, picking up the old ones and putting down new ones. If there is anything area where I tend to see more of them, I lay more down- and it seems to be best if they aren’t blocked by items. I also notice that the areas where they are seem to sometimes have little spiders nearby, which I assume are eating the silverfish… so when cleaning I given extra attention to those areas. If I replace them in the 4 months (that’s how long they seem to last before I see another one) I rarely spot one.

The only thing that actually works on silverfish!!!!!!

Really hoping this would work, it did not! Very disappointed. Waste of money.

Can’t say if this helped but seeing few silverfish after throwing the pack in every corner

They work great but you need to use a lot of them to have the best effect. They are also just boric acid so they aren't toxic like the synthetic pesticides that you spray. The silverfish are attracted to them and eat the boric acid then leave them and die later. I haven't seen one since I put all of the traps out. I would buy even more. I didn't even need to spray with the more toxic stuff I bought.
