FLYGRUBS® are Black Soldier Fly Larvae – a high-protein hen treat with 85x more calcium than dried mealworms. FLYGRUBS BSFL are also sustainable, organic grain free feed and naturally support your hens immune system.

A Healthier Choice

Flygrubs are nutrient dense and contain Lauric Acid (aka healthy fats), with strong antimicrobial properties to help prevent and fight bacteria, and other infections. When comparing to mealworms, which contain lower calcium levels and no Lauric Acid, which are ultimarely not as healthy as Black Soldier Fly Larvae.

Sensible Premium Treats

Flygrubs are an all-natural, premium chicken feed additive & molting supplement for layer hens. Backyard farmers want what’s best for our ladies, and when we consider the cost of alternative protein & calcium supplements, FLYGRUBS makes sense. We always recommend feeding in conjunction with a balanced layer feed.

The Earth Thanks You

We’re turning food waste destined for landfills into hen treats. Food waste in landfills produces methane that negatively affects the climate (about) 20x worse than carbon dioxide. Studies show as low as 3% of food waste is recycled worldwide! Our grub worms are a renewable feed additive, raised on traceable food and organic waste.

Farmers That Care

Flygrubs is owned and run by Americans and we care deeply about three things. Our families, our chickens, and our environment. Every step of the way, we work very closely with our farms and farmers to ensure our grubs stay healthy, USA FDA Approved and economical.
