Starting a cricket farm requires a climate-controlled space, the right species, a reliable feeding program, and a plan for what you’ll do with the harvest. The startup costs are relatively low compared to traditional livestock, and crickets convert feed into protein far more efficiently. Here’s what you need to know to get from empty room to functioning farm.
Choosing the Right Species
Three species dominate commercial cricket farming: the house cricket (Acheta domesticus), the banded cricket (Gryllodes sigillatus), and the two-spotted cricket (Gryllus bimaculatus). Your choice depends on what you’re raising them for and how much risk you’re willing to take.
The house cricket is the most widely farmed and best-studied species. It’s the default for human food production in North America and Europe. The catch is that it’s vulnerable to a specific virus, Acheta domesticus densovirus, which has collapsed entire commercial colonies in the United States. If this virus gets into your stock, you can lose everything.
The banded cricket has gained popularity specifically because it resists that virus. Taste-wise, defatted banded crickets are indistinguishable from house crickets. When sold whole, the flavor differs slightly due to fat content, but for most processed products this doesn’t matter. The two-spotted cricket matures faster, reaching harvest size in about 42 days compared to 49 for house crickets, which means faster turnover per bin. Many farms now keep banded or two-spotted crickets as their primary stock and maintain house crickets only as a secondary line.
Setting Up Your Space
Most cricket farms use vertical bin systems to maximize floor space. A standard commercial setup uses open-air plastic bins roughly 3 feet wide, 5 feet long, and 2.5 feet deep, stacked on shelving units. Each bin holds around 4,000 crickets. You can fit dozens of bins in a modest room, which is why cricket farming works in warehouses, garages, basements, and shipping containers.
Inside each bin, you’ll need vertical surfaces for the crickets to climb and hide. Egg cartons or corrugated cardboard panels stacked vertically give crickets the surface area they need while preventing overcrowding on the floor. A shallow water dish with sponges or water crystals prevents drowning while keeping humidity up. Feed trays should be easy to remove and clean daily.
Stocking density matters more than most beginners realize. Overcrowding stresses crickets and weakens their immune systems, making them more vulnerable to viral outbreaks. Lower densities produce healthier batches. Start with fewer crickets per bin than you think you need and scale up as you learn how your specific setup handles airflow, waste, and humidity.
Temperature and Humidity Control
Crickets are cold-blooded, so your environmental controls directly determine how fast they grow, how successfully eggs hatch, and whether your colony thrives or stalls. The target temperature for adult rearing and egg production is around 29 to 34°C (84 to 93°F), with an average near 31°C (88°F). Humidity during this phase should stay between 50% and 85%, ideally around 70%.
Egg incubation requires slightly more precision. House cricket eggs hatch best at 30°C (86°F) with relative humidity between 65% and 75%. Two-spotted cricket eggs prefer 31°C at 70% humidity. Even a few degrees off can dramatically reduce hatch rates, so invest in a reliable thermostat and hygrometer for your egg incubation area. Many farms keep a separate, smaller incubation chamber where conditions can be tightly controlled.
For nymph growth, temperatures in the 27 to 32°C range (80 to 90°F) produce the best weight gain. The simplest approach is to keep your entire facility at a steady 30°C with humidity around 70%, which covers all life stages reasonably well. Space heaters with thermostats work for small operations. Larger farms use HVAC systems or radiant heating panels. In dry climates, you may need a humidifier or misting system.
Understanding the Life Cycle
Crickets go through three stages: egg, nymph, and adult. There is no pupal stage like butterflies or beetles, which simplifies management considerably.
Eggs incubated at 25°C hatch in about two to three weeks. At higher temperatures closer to 30°C, hatching accelerates. The relationship follows a predictable curve: for every degree above 14°C, development speeds up. At optimal incubation temperatures, you can expect hatching in 10 to 14 days.
Nymphs look like tiny adults without wings. They molt multiple times over the next six to seven weeks, growing larger with each molt. House crickets reach adult size in roughly 49 days from hatching, while two-spotted crickets get there in about 42 days. Adults are ready for harvest once they’ve reached full size, or you can keep a portion as breeders. Adult females lay eggs in moist substrate (coconut coir or damp peat moss works well) within days of their final molt, and a healthy colony will continuously cycle through all three stages once established.
To maintain a steady harvest, stagger your bins so new batches start every week or two. This way you always have bins at different stages of development, providing consistent output rather than boom-and-bust cycles.
Feeding for Fast Growth
Crickets are omnivores, and what you feed them directly affects how fast they grow and how efficiently they convert that feed into body mass. The feed conversion ratio (FCR) for house crickets ranges from about 1.5 to 1.8, meaning they need only 1.5 to 1.8 pounds of feed to produce one pound of body weight. For comparison, cattle require roughly 6 to 8 pounds of feed per pound of weight gain. This efficiency is one of the biggest economic advantages of cricket farming.
The key variable is protein content. Crickets thrive on diets with 18 to 22% protein, and higher-protein feeds produce the best feed conversion. A 22% protein diet yields an FCR around 1.5, while a 16% protein diet pushes FCR up to 1.8, meaning you’re spending more on feed for the same amount of cricket. Poultry starter feed (available at any farm supply store) typically hits the right protein range and is the most common base feed for small and mid-size cricket farms.
Supplementing dry feed with fresh vegetables or fruit scraps adds moisture and micronutrients. Pumpkin pulp, leafy greens, and carrots all work well. Fresh foods also reduce the need for separate water sources, though you should still provide water crystals or damp sponges. Remove uneaten fresh food daily to prevent mold, which can devastate a bin quickly.
Harvesting and Processing
The standard humane method for killing crickets is cold exposure. Placing them in a freezer renders them unconscious as their body temperature drops, and they die without signs of distress. This is the most practical method for small to mid-size farms and is widely accepted in the industry.
After freezing, you have several processing options depending on your end market. For whole dried crickets, oven drying at low temperatures (around 200°F for several hours) or freeze-drying produces a shelf-stable product. For cricket powder or flour, dried crickets go through a grinder. Some processors skip the drying step entirely and grind frozen crickets directly, though this requires immediate further processing or cold storage since the high moisture content makes the product perishable.
Drying is the most common first step because it reduces weight for storage and shipping, extends shelf life, and makes grinding easier. Solar drying, oven drying, microwave drying, and freeze-drying are all used commercially. Freeze-drying preserves protein quality best but costs the most. Oven drying is the most accessible for new farms.
Navigating Food Safety Regulations
In the United States, the FDA regulates insects sold as human food under the same framework as any other food product. Crickets must be raised specifically for human consumption following current Good Manufacturing Practices (cGMP). You cannot collect wild crickets or repurpose pet-feeder crickets for human food due to contamination risks.
The regulatory landscape has a notable quirk. Edible insects don’t require explicit pre-market FDA approval. Instead, they fall under the “Generally Recognized as Safe” (GRAS) framework, where a manufacturer can self-determine that their product is safe based on scientific evidence or a long history of human consumption. This self-determination is voluntary, and the FDA doesn’t need to be notified. While this lowers the barrier to entry, it also means you bear full responsibility for food safety.
The cGMP rules present an ironic challenge for cricket farmers: federal food safety regulations require that “no pests shall be allowed in any area of a food plant,” and the legal definition of “pests” includes insects. In practice, regulators understand the difference between farmed crickets and pest contamination, but your facility needs to demonstrate clear containment. Keep your farming area clean, prevent wild insects from entering, and document your sanitation procedures. If you’re selling across state lines, register your facility with the FDA as a food production establishment. State and local health departments may have additional requirements, so check with your county before selling.
Revenue Streams and Economics
Cricket farms generate income from multiple products. Whole live crickets sell to pet owners and reptile breeders at roughly $10 to $20 per thousand. Dried crickets and cricket powder command higher prices in the human food market, where protein bars, snack foods, and cricket flour are the main retail categories. A third revenue stream that many new farmers overlook is frass, the cricket waste product.
Cricket frass is a surprisingly valuable organic fertilizer. It contains nitrogen, phosphorus, and potassium in a ratio of approximately 4.7:1:1.2, which is close to the proportions found in many commercial NPK fertilizers. It can be sold to gardeners, organic farms, and hydroponic operations. Since you’re producing frass continuously as a byproduct of farming, it’s essentially free revenue once you set up packaging and sales channels.
The biggest ongoing costs are feed, heating, and labor. Feed is your largest expense, but the favorable conversion ratio keeps costs per pound of output low compared to traditional animal protein. Heating can be significant in cold climates, since you need to maintain tropical temperatures year-round. Labor scales with the number of bins: each bin needs daily feeding, water checks, waste removal, and monitoring. Start small enough that you can manage the work yourself, learn the rhythms of the colony, and expand once your processes are dialed in.
Preventing Disease and Colony Collapse
The single biggest threat to a cricket farm is viral disease, particularly the Acheta domesticus densovirus. This virus spreads rapidly through dense populations and can wipe out an entire facility’s stock. Prevention is far easier than treatment, because there is no treatment.
Biosecurity starts with your source stock. Buy from reputable breeders with documented disease-free colonies. Quarantine new crickets in a separate area for at least one full growth cycle before introducing them to your main population. Keep separate tools and containers for each batch, and wash your hands between handling different bins. Consider farming banded crickets as your primary species, since they’re resistant to the densovirus that devastates house crickets.
Beyond viral threats, maintain good hygiene by removing dead crickets and frass regularly, ensuring adequate ventilation to prevent ammonia buildup, and keeping humidity in the right range to discourage mold. High-quality nutrition and reasonable stocking densities reduce stress and keep immune systems stronger across your colony.
