Watch your clever eco hack turn into the local Bed and Breakfast for Bugs. Those stacked rocks aren't just a border anymore, they're prime real estate for every spider and beetle in the county. Congrats, you didn't just reuse materials, you built a full five star resort with zero security deposit. Guess the whole "if you build it, they will come" thing applies to pill bugs too. Your garden's edge is now a thriving ecosystem you never meant to manage. Nature saw your free housing and said THANK YOU VERY MUCH.
Feel your pain on that one. I tried the same thing with old bricks last summer and wound up hosting more millipedes than I could count. Sometimes the best green ideas come with a bunch of tiny, unexpected roommates. You've got to admire nature's ability to move into any open space, even if it wasn't part of the plan.
It's wild how many small eco choices turn into nature management projects. Like @blair_gonzalez80 finding that nest, my compost bin once attracted every raccoon on the block. We try to do one good thing, like stacking old bricks, and suddenly we're running a bug hotel. It's like the planet sees a tiny opening and sends in the welcoming committee, turning our simple reuse into a full time side gig we never signed up for.
