Well howdy, fellow worm farmers! I’ve been a worm rancher for a few years now. They’re great for fishing. They’re good for your garden. And they tear into kitchen scraps like a pack of wild hogs. Very tiny, very numerous, wild hogs. But worm bins can develop problems.
One problem that creeps up from time-to-time in the life of a worm farmer is fruit flies. If you keep your bins outdoors flies are no big deal, but if you keep them inside they can beproblematic. Here’s how to prevent and eliminate fruit fly infestation in your work bins.
Add a digestible bedding material to the top of your bins! I like to use sawdust or shredded paper, as I have both in abundance. You can use pieces of cardboard to the same affect. What I do is fill a five-gallon bucket halfway with bedding material. Then I start adding water, and mix until the material is soft and fully saturated. I cover the top of the bin with about a half inch of bedding material. Fruit flies won’t dig for their food, so this layer will discourage them from making your worm farm their forever-home, laying eggs, and making your worm bins the family estate. Over time your worms will eat the bedding, turning more trash into black gold for your garden.
Bonus Tip: Already have flies in your worm bins? Not to worry! Grab your Shop-Vac and go to town. You can easily suck up the majority of your fruit flies by popping open the kid of your bin and sucking them up in mid-air.
