GrubTerra began in 2019, when our founder and CEO, Michael Servais, set out to build a company that could feed animals well and help the environment at the same time. Then he discovered black soldier fly larvae: tiny grubs that turn food waste into rich, natural protein.
He started raising the larvae himself. After a lot of trial and error, a crowdfunding campaign brought in enough early pre-orders to move GrubTerra into a full-scale production facility.
“I started GrubTerra to make the biggest positive impact on the environment that I could. Feeding chickens better turned out to be the way to do it.”
Michael Servais, Founder & CEO
Every 1 lb of our larvae upcycles about 20 lbs of food waste.
Larvae were just the beginning. As our community of flock keepers grew, so did their needs, and we grew right along with them: into holistic care for the whole backyard flock, with supplements for daily gut defense and gut support, all-in-one vitamins and a fresher coop.
And we're not stopping there. A GrubTerra feed line and products for other animals are on the way, made with the same care, because chickens are more fragile than most people realize and the people who love them deserve real peace of mind.
“I started GrubTerra to make a positive impact on our environment while giving pets and livestock the best-quality nutrition possible.”

“My hens are absolutely bonkers for these black soldier flies! … They are plump, healthy, contented birds. … These are an irreplaceable part of my hens' daily routine and health, and it's good for the environment because these flies consume waste during production.”
“I used to get a cheaper brand from China, but wanted something better for my hens. … My hens make the final decision with a taste test. … All 32 hens picked Grubterra over their old cheaper brand. They're happy with their morning treats, so I'm happy.”
“We feed Peck Purity to all of our poultry. From or chicks to our layers even our quail get it in their feed. Our egg production has improved because our flocks are healthier!”
“The black soldier fly larva are one of our flock’s favorite treats! As soon as they hear the bag rustle, they come running! Happy to have found a product that is healthy and a well loved protein source for our chickens, ducks, and goose!”
“We used to have dirty, gross eggs. Now, look at them after just 2 weeks using hen harmony!”
“I've got 30 chickens so I make 2 treat pans for them with Peck Purity on top and they can't get enough. Their poops are firm and their vents are almost sparkly clean! I give that credit to Peck Purity, love this product! Thank you, my girls love it and I'll never stop buying it.”
