Freezing kills pests

You all know to freeze any dry goods you bring into your home for at least 72 hours to kill off any bugs, but did you know that you can freeze other things that may be contaminated with creepy crawlies too? For a chemical free bug treatment when you bring clothing and other textiles, books etc home, put the items in a ziplock bag and freeze them. This is especially important for second hand items. They often harbour silverfish, cockroach or moth eggs, which you can't easily see and freezing will kill them. Then you can wash the clothing and dust the books and know you won't be bringing any pests into your home.
