Farmers That Care

We’re Americans who care about our families, chickens, and the environment. FLYGRUBS are raised sustainably and economically. They make a great snack for ducks, songbirds, turtles, and reptiles.

Why are Backyard Chicken Farmers choosing FLYGRUBS over mealworms?

You may already be aware that Black Soldier Fly larvae are HIGH-PROTEIN hen treats with 85x MORE CALCIUM than dried mealworms. Did you also know dried BSFL is a sustainable, organic grain free feed that supports your hen's immune system ?


A daily handful helps to promote STRONGER EGGSHELLS which means HEALTHIER HENS. But it’s not all about your chickens! Your family will notice the difference too! If your family loves fresh eggs as much ours does, FLYGRUBS are your choice.


FLYGRUBS come in a resealable bag made from recycled plastic, that’s CAREFULLY PACKED into a box to ensure you don't receive broken and small pieces!


Please remember to be patient when giving your girls a NEW TREAT. It may take some time before they start to LOVE them.

Choose happiness And health for your girls.
