It’s harvest season, and once your garden’s bounty is safely indoors, you can continue to vigilantly protect it from pests without resorting to chemical solutions by using this clever fruit fly trap tutorial put together by the folks at apartment therapy.

I know this trick has been around for a while (because I used it to collect specimens for a science fair project when I was a kid!), but if you’ve never seen it before, it’s a handy thing to know how to do because it really works!
