Backed by Nature

Made in the USA

Puregrubs larvae are farm raised in the USA only. We support small farms in America. These black soldier fly grubs are 100% sustainably-grown. BSFL can consume food scraps and agricultural byproducts—transforming waste that would otherwise go to landfills into high-value protein and compost. BSFL farming can be done in compact spaces and uses significantly less water than traditional livestock, making it ideal for sustainable agriculture. When raised on American farms, BSFL keep resources local—turning nearby waste into feed and fertilizer instead of relying on imported inputs.
