Cricket Farm Standard Operating Procedure Templates

FDA auditors increasingly request SOP documentation from cricket flour facilities even for Qualified Facility exemptions. SOPs also solve a problem that has nothing to do with regulators: they make your operation consistent regardless of who's doing the work, which reduces die-off events, improves FCR, and keeps your buyers' quality expectations met reliably.

This guide provides ready-to-use SOP templates for the core tasks on a commercial cricket farm. Adapt each template to your specific operation - the species, bin type, environmental targets, and procedures that match your setup.

TL;DR

• Lightly mist substrate to approximately 30-40% moisture (squeeze test: substrate clumps slightly but doesn't drip)
• Place egg carton sections or other hide structures in bin - approximately 3-4 vertical layers
• Allow 30 minutes for bin to reach ambient temperature before stocking
• Install fresh substrate at 2-3 inch depth
• Let bin sit for 2 hours before stocking if substrate required notable moisture adjustment
• If a single bin shows more than 10% of apparent population dead in one day: flag the bin, do not add new crickets, check temperature and humidity in that zone, and note in the management system
• If temperature is below 80F: treat as urgent

How to Use These Templates

Each SOP template follows the same structure:

• Purpose: What this procedure accomplishes
• Frequency: How often it's performed
• Supplies needed: What to have ready
• Procedure: Step-by-step numbered instructions
• What to log: What gets recorded in your management system
• What to do if something looks wrong: Decision tree for anomalies

Print these as laminated cards or load them into your farm management platform as reference documents. They work best when they're physically present at the point of use, not in a binder on a shelf.

SOP Template 1: Bin Setup and Stocking

Purpose: Establish a new production bin consistently, ensuring the environment is correct before stocking.

Frequency: Per new production cycle (when a bin is being started fresh after harvest)

Supplies needed: Clean bin, ventilated lid, substrate material, hide structures (egg carton sections), thermometer, spray bottle (for substrate moisture)

Procedure:

1. Confirm the bin is clean and dry. No residue from previous cycle.
2. Install fresh substrate at 2-3 inch depth. For Acheta domesticus: wheat bran or commercial insect substrate.
3. Lightly mist substrate to approximately 30-40% moisture (squeeze test: substrate clumps slightly but doesn't drip).
4. Place egg carton sections or other hide structures in bin - approximately 3-4 vertical layers.
5. Place a shallow water dish at one end.
6. Replace ventilated lid and confirm secure fit.
7. Place bin in assigned shelving position.
8. Allow 30 minutes for bin to reach ambient temperature before stocking.
9. Record bin setup in CricketOps: bin number, setup date, substrate type, assigned shelf position.

Log in management system: Bin number, setup date, substrate batch, shelf assignment

What to do if substrate is too wet or too dry: Add dry substrate or re-mist as needed. Let bin sit for 2 hours before stocking if substrate required notable moisture adjustment.

SOP Template 2: Feeding Protocol

Purpose: Provide consistent nutrition on schedule, logged per bin.

Frequency: Daily (or per farm schedule; minimum every 48 hours for adults)

Supplies needed: Feed (commercial cricket feed or formulated blend), food-grade scoop, water gel or hydration dishes

Procedure:

1. Check feed supply before starting. Don't begin feeding rounds if supply is insufficient to feed all bins.
2. Starting at the top shelf of each shelving unit, work top-to-bottom, left-to-right.
3. Remove old food dishes before adding new feed. Old feed should be removed if not consumed from the previous feeding. Note whether previous feeding was largely consumed or left - notable leftover feed may indicate a problem.
4. Add fresh feed in the appropriate quantity for the bin's current life stage and stocking count:

- Pinheads (0-7 days): fine-grind feed only, very small quantities daily

- Nymphs (7 days - 4 weeks): standard feed, daily

- Sub-adults and adults (4+ weeks): standard feed, daily or every 48 hours

1. Refresh water gel or water source in each bin.
2. Check for dead crickets during feeding. Note any obvious mortality anomalies.
3. Log feeding event in management system.

Log in management system: Date, time, feed quantity (if tracked), any anomalies noted

What to do if feed is consistently not consumed: Check bin temperature, check for signs of disease, note the bin number in your management system with "consumption anomaly" flag.

SOP Template 3: Mortality Logging

Purpose: Track die-off accurately to calculate die-off rate and identify health problems early.

Frequency: Daily (at minimum, at each feeding)

Supplies needed: Counting tray or container, management system access

Procedure:

1. During each bin check, remove any dead crickets from each bin.
2. Place removed crickets in a counting container. Count the total.
3. Log the count per bin in the management system with the date and time.
4. Dispose of dead crickets appropriately (compost or waste, not back into production).
5. If a single bin shows more than 10% of apparent population dead in one day: flag the bin, do not add new crickets, check temperature and humidity in that zone, and note in the management system.

Log in management system: Bin number, date, mortality count

What to do if high mortality is observed: Check temperature in that bin's zone. Check for signs of pathogen (unusual odor, discolored crickets, behavioral changes in surviving crickets). Isolate the bin from others if disease is suspected. Log all observations.

SOP Template 4: Environmental Check

Purpose: Verify that temperature and humidity in all production zones are within target range.

Frequency: Minimum twice daily (morning and afternoon); continuous if using automated sensors

Supplies needed: Calibrated thermometer and hygrometer (or review of automated sensor logs)

Procedure:

1. Review sensor data in CricketOps dashboard (if using automated sensors) or check thermometers in each zone.
2. Record temperature and humidity for each zone in the management system.
3. Target ranges:

- Production temperature: 85-90F (Acheta domesticus)

- Hatching temperature: 90F ±1F

- Humidity: 60-70% RH in production areas; 65-75% in hatching area

1. If any zone is outside target range: note the deviation, identify the cause (HVAC issue, thermostat drift, external temperature change), and correct.
2. If temperature is below 80F: treat as urgent. Check HVAC function immediately.
3. If temperature is above 95F: treat as emergency. Engage cooling immediately.

Log in management system: Zone, temperature, humidity, date, time, any anomalies or corrections

SOP Template 5: Harvest Procedure

Purpose: Harvest production bins efficiently and consistently, logging output accurately.

Frequency: Per harvest window (typically weeks 6-8 post-hatch for Acheta domesticus)

Supplies needed: Drum separator or sifting equipment, collection containers, scale, packing materials

Procedure:

1. Confirm harvest readiness: bin date indicates week 6+ post-hatch, visually confirm majority of crickets are adult-sized.
2. Remove water sources and food dishes from bin 12-24 hours before harvest. This allows gut to empty slightly, which is helpful for food-grade product and reduces escape risk during harvest.
3. Set up drum separator (or sifting station).
4. Transfer crickets from bin to drum separator. Process through to separate crickets from frass and substrate.
5. Weigh harvest yield on calibrated scale. Record weight.
6. Size-grade if required for your market.
7. Package into delivery containers. Label with harvest date and size grade.
8. Clean and sanitize empty bin immediately after harvest.
9. Log harvest in management system: bin number, harvest date, yield weight, any anomalies.

Log in management system: Bin number, harvest date, starting stocking count (from setup record), harvest yield weight, size grade

What to do if yield is measurably below expectation: Note the shortfall and compare against die-off rate logged during the cycle. If die-off was high, this explains the yield shortfall. If die-off was normal, check whether the cycle was harvested late (adults dying of old age) or early (crickets not fully grown).

Using SOPs for FDA Compliance

FDA auditors reviewing a cricket flour facility's food safety plan will look for documented procedures that match the preventive controls identified in the hazard analysis. Your feeding SOP supports your allergen control documentation (if your feed ingredients are tracked). Your mortality SOP supports your monitoring records. Your environmental check SOP supports your temperature monitoring records as a documented critical control point.

CricketOps stores your SOP documentation alongside your production records, so when an auditor asks to see your procedures and the records that demonstrate those procedures are being followed, everything is in one place. For the full record-keeping framework, see the cricket farm record-keeping guide.

Frequently Asked Questions

What SOPs should a cricket farm have in place?

At minimum, a commercial cricket farm should have written SOPs for: bin setup and stocking, daily feeding, daily mortality logging, environmental monitoring, harvest procedure, and post-harvest bin sanitation. Operations producing food-grade product also need SOPs for allergen control, pathogen testing, and any critical control points in their food safety plan. Start with the core production SOPs (feeding, environmental monitoring, mortality logging) and add food safety SOPs as you build toward FSMA compliance. The goal is that any trained employee can perform each task correctly from the SOP, without needing to ask you for guidance.

Do SOPs help with FDA compliance for a cricket flour producer?

Yes, and in two ways. First, SOPs are the written evidence that your food safety procedures are systematic and deliberate, not ad hoc. An FDA inspector reviewing your facility expects to see documented procedures that match your food safety plan's preventive controls. Second, SOPs improve the consistency of your actual practices - which means your monitoring records are more likely to reflect good performance rather than random variance. Inconsistent practices produce inconsistent records, and inconsistent records create compliance risk. FDA facilities that fail inspections often have food safety plans that describe practices that don't actually happen consistently on the floor.

Where can I find SOP templates for a cricket farm?

This guide provides templates for the core production SOPs. CricketOps provides additional food safety plan templates and compliance SOP templates for operations building toward FSMA Preventive Controls compliance. For generic food safety SOP templates that can be adapted for cricket flour, the Food Safety Preventive Controls Alliance (FSPCA) publishes resources in conjunction with their PCQI training program. Whatever template you start with, adapt it specifically to your operation's procedures, species, and equipment - a template that doesn't match your actual practice isn't useful for training or compliance.

How do I recover a cricket bin after an accidental temperature spike?

First, restore the target temperature for that life stage immediately. Remove any dead crickets to prevent ammonia buildup and monitor the bin closely for the next 48-72 hours. If you see continued elevated mortality, assess whether the colony has enough healthy population to recover or whether early harvest is the better option. Maintaining a detailed temperature log makes it easier to understand how severe the event was and adjust heating protocols to prevent a repeat.

What is the best way to measure temperature inside a cricket bin accurately?

A digital probe thermometer placed at mid-bin height, away from heating elements and exterior walls, gives the most representative reading for the cricket population's actual environment. Infrared (non-contact) thermometers measure surface temperature only and frequently give misleading readings in bin environments. Data-logging sensors that record continuously are preferable to manual spot-checks, since swings between readings can go undetected.

How much does electricity cost to maintain target temperatures in a cricket facility?

Energy cost varies significantly by facility size, climate, and insulation quality. A well-insulated small operation (under 30 bins) in a moderate climate typically adds $40-$80/month to electricity costs for heating. Larger commercial facilities in cold climates can spend $300-$800/month or more during winter months. Improving building insulation is usually the highest-ROI investment for reducing heating costs compared to upgrading heating equipment.
