To build one, you'll need a rod or piece of PVC pipe, some superglue, a piece of string, a paper clip, and—perhaps the most elusive requirement of the bunch—an empty cassette tape case that can open and close easily. To avoid harming the spider, we suggest positioning the open case near it with the rod's help, then let the creature come to you. The project is a clever alternative to your more basic paper towel and cup approach.
Check out the full post below for a step-by-step guide, including pictures, on how to build the catcher. If you have other spider-friendly trapping methods, we'd love to hear them.
