This is perhaps the easiest way to catch worms and it’s absolutely free. Better yet, no digging is involved. So where do you catch worms? Well, in your own backyard, of course! Below is a video that shows how to capture earthworms without digging in the ground. Get what you need for fishing, food for your pet, or for starting a worm farm. All you need is one garden fork and fine moist soil. This method will not work with dry soil. The author of the video mentions, however, that if you have dry soil then you can lay a wet carpet down on the ground and the moisture underneath the carpet will attract worms to live there.
