Baking soda is that quiet household multi-tool that doesn't seek attention, but then it shows up everywhere: in baking, in the fridge, in cleaning tricks, and now in home pest control. It's not glamorous, it doesn't have the "alpine freshness" perfume, and it doesn't promise instant miracles — but that's exactly why it's interesting. It's a simple, cheap, dry, slightly alkaline substance that can help create a less hospitable environment for some little intruders in your home.
