There's a particular kind of magic that happens when a kid realizes a pile of sticks and pinecones can become a five-star resort for ladybugs. Suddenly the backyard isn't just the backyard anymore — it's an ecosystem, and they're the innkeepers. Building a bug hotel is simple enough for an afternoon, costs almost nothing if you're willing to scavenge, and teaches kids that "pests" and "pollinators" aren't just vocabulary words. They're neighbors — and every one of them has a job to do in your garden.
