A thread for tips would be a great idea.
The boric acid seems to be working for us. Seems similar to the stuff Dave uses, but it’s a very fine powder. the little sods use to be all over the place. Not been out now since October, so will be interesting to see how it all is in Jan when we go back. I placed fresh acid around all the skirting before we left, so a tell tale sign would be dead silverfish in the rooms. Last time we done this there were only a few dead ones, and no live ones munching away on my books or hiding in the cupboards.
Another tip for any nasty smells in the house or in the fridge freezer after the delights of coming back after a power cut is cat litter. Have used it a few times, but now it’s fridge and freezer off before we come home.
