Wild bird products that make a difference


EnterraGrubs™ are shaping up to be a breakthrough in bird food for the reason most important to bird feeding hobbyists everywhere: Black Soldier Fly larvae, more than mealworms, better fulfill every bird lovers’ desire for more birds to visit their feeders.

Mealworms are a good source of protein, but they can’t compete with the Black Soldier Fly larvae’s irresistible appeal to birds. EnterraGrubs™ contain a naturally high level of calcium, plus an ideal calcium:phosphorus ratio that promotes strong bones and healthy reproduction in many bird species.

EnterraGrubs™ contain a naturally high level of calcium, plus an ideal calcium:phosphorus ratio that promotes strong bones and healthy reproduction in many bird species. The high level of lauric acid, which has antimicrobial benefits, provides a more balanced fatty acid profile to provide an energy boost during the winter or reproductive periods.

Insects are a natural component of the diets of many bird species. In North America, approximately half of all bird species consume insects at some point during the year.

How EnterraGrubs™ benefits wild birds



Mealworms can’t compete with the amount of calcium found in our grubs. Combined with the natural calcium-to-phosphorus ratio of 1.5-2.5:1 for EnterraGrubs™, compared to 0.12:1 for mealworms, birds absorb more of the high calcium content from the grubs. This encourages healthy bones, eggshells and reproduction, helping the bird species you and your customers love to thrive.



Trial results have shown that 50% more birds visited feeders with EnterraGrubs™ than dried mealworms when given the option. They also consumed EnterraGrubs™ at a 48% faster rate, helping them gain the nutrients they need quicker.



The high-quality of the Black Soldier Fly larvae starts with the feedstock – being raised on 100% government-approved, pre-consumer food waste like fruits, vegetables and grain. Being produced in North America means the grubs can also be reliably shipped and cost less in transportation.
