Supplement your flock’s feed with Mealworms by the Pound Black Soldier Fly Larvae Treat. Grown in North America, these all-natural, GMO-free, dried black soldier fly larvae are easier to use than live larvae, as you can just grab a handful and toss them to your birds as needed. These little larvae are rich in protein, making them a healthy treat for your chickens, turkeys, ducks, and other fowl. You can also use them to boost the protein levels in your wild bird feeder, as they are great for bluebirds, woodpeckers, and more.
