Crickets (Acheta domesticus and Related Species)

What it is

The house cricket (Acheta domesticus) and related cricket species are the primary species farmed in Western insect food operations and are among the most widely consumed insects globally across both traditional and emerging markets.

Acheta domesticus (house cricket) — the dominant farmed species in North America and Europe. Gryllus bimaculatus (two-spotted cricket) — commonly farmed in Asia. Multiple wild cricket species consumed across Mexico, Africa, Southeast Asia, and South America.

How it's made (farmed): Industrial cricket farming involves raising crickets in controlled-temperature (approximately 30°C) facilities with humidity management, in bins or stacked trays with feed (typically grain-based with moisture supplementation). Crickets complete their life cycle in approximately 6–8 weeks, reaching harvest size as mature adults. They are harvested by freezing (which kills them humanely, avoiding the chitin-hardening that occurs with heat killing prior to death), then processed by drying (in ovens or drum dryers), and either sold as whole roasted crickets, ground into cricket powder/flour, or further processed into protein isolate.

Food uses & preparation

Nutty, earthy, slightly savory with a mild grassiness. Roasted whole crickets develop Maillard flavors that are similar to roasted nuts or popcorn. Cricket powder has a mild flavor that integrates well into baked goods, smoothies, and protein products.

Nutritional Profile: Protein: 65–70% dry weight. Complete amino acids. Iron: approximately 5.2 mg/100g dry weight. Zinc: 13.8 mg/100g. B vitamins. Omega-3 fatty acids. Feed conversion: approximately 1.7 kg feed per kg body mass.

Culinary Uses (Traditional): In Mexico, multiple cricket species are consumed (see chapulines, above). In Thailand and Southeast Asia, crickets are fried and seasoned as snack foods. In East Africa (particularly Uganda and Kenya), field crickets are harvested seasonally and fried or smoked. In Japan, traditional inago (field cricket/grasshopper) preparations involve boiling in soy sauce and sugar, producing a sweet-savory preparation served as a condiment over rice.

Culinary Uses (Western): Cricket flour/powder as a protein supplement in baked goods, protein bars, smoothies. Whole roasted seasoned crickets as a snack food. Cricket-fortified pasta, chips, and crackers.
