If you’re like me, sometimes you get sick of buying your own bait. One of my buddies showed me this handy tip for catching nightcrawlers at home and now I do it all the time.
To catch some worms, grab a small cup full of ammonia, or any ammonia-containing chemical such as many glass cleaning products, and pour the ammonia onto any small, concentrated patch of soil outdoors. The ammonia depletes the oxygen below the surface temporarily, and worms have no choice but to crawl to the surface for air. You’ll be surprised at the quantities. Once they start getting to the surface, take your pickings.
With this tip in mind, you can be catching plenty of “home-grown” nightcrawlers in no time. And saving money too!
