Cricket Farm Pest Exclusion Plan: Keeping Pests Out of Your Facility

FDA considers an inadequate pest control program to be a serious Good Manufacturing Practice (GMP) violation. For cricket flour producers, pest exclusion presents a specific irony: you're raising insects, and your facility conditions (warmth, feed, moisture) that are ideal for cricket production are also attractive to rodents and cockroaches. A cricket farm that hasn't thought carefully about pest exclusion is a facility that FDA inspectors will notice.

This guide covers how to develop a written pest exclusion plan for your facility, the physical controls required, and how to document your program in a way that satisfies FSMA GMP requirements.

TL;DR

• Rodent exclusion: Seal any gap larger than 1/4 inch in the building envelope
• Rodent exclusion: Seal any gap larger than 1/4 inch in the building envelope
• Under 21 CFR Part 117 (FSMA GMPs), pest control is a required sanitary condition
• Keep at least 2 years of pest monitoring records
• FSMA's GMP requirements (21 CFR Part 117 Subpart B) require that food facilities take effective measures to exclude pests from food processing areas and to protect food from pest contamination
• Keep all records for at least 2 years
• Shared equipment such as scoops, scales, and thermometers are common transmission vectors and should be dedicated per bin or sanitized with a 70% isopropyl alcohol solution between uses

Rodent exclusion: Seal any gap larger than 1/4 inch in the building envelope.

• FDA considers an inadequate pest control program to be a serious Good Manufacturing Practice (GMP) violation.
• A cricket farm that hasn't thought carefully about pest exclusion is a facility that FDA inspectors will notice.
• Most chemical pesticides are harmful to crickets and would contaminate your product.
• Document station locations, inspection frequency (at minimum monthly), bait consumption observations, and any rodent activity evidence.
• Never place rodent bait stations inside cricket production areas.

Pest Monitoring Schedule: Define the frequency and method for inspecting all monitoring devices.

• Store feed in sealed, pest-resistant containers or in a dedicated feed storage area with its own exclusion measures.

Why Pest Exclusion Is Especially Important for Cricket Farms

Pest control in a cricket flour facility requires a different approach than a standard food facility because you can't use many common pesticide applications inside the production area. Most chemical pesticides are harmful to crickets and would contaminate your product. This means:

• You cannot spray pesticides inside your cricket production or processing areas
• You cannot use glue boards or snap traps in locations where they could contaminate product
• Your primary pest control must come from exclusion (keeping pests out) rather than chemical elimination

This makes facility design and physical exclusion more important for a cricket farm than for most food facilities.

What a Written Pest Exclusion Plan Includes

Facility Map: A diagram of your production facility showing all pest entry points (doors, windows, vents, utility penetrations, floor drains), pest monitoring device locations (bait stations, glue boards in non-production areas, pheromone traps), and pest sighting log locations.

Entry Point Inventory: For each potential pest entry point, document the exclusion measures in place:

• Exterior doors: self-closing hardware, door sweeps, threshold seals
• Windows: screens in good repair, sealed frames
• Utility penetrations (pipes, conduit): sealed with escutcheon plates or caulk
• Roof vents and soffit vents: screened, sealed
• Floor drains: equipped with backflow prevention

Rodent Bait Station Log: Bait stations must be placed on the exterior perimeter of the building and in non-production areas where rodents might enter. Document station locations, inspection frequency (at minimum monthly), bait consumption observations, and any rodent activity evidence. Never place rodent bait stations inside cricket production areas.

Pest Monitoring Schedule: Define the frequency and method for inspecting all monitoring devices. Monthly is standard; increase frequency if pest activity is detected.

Pest Sighting Reporting Procedure: Any employee who sees a pest (rodent, cockroach, stored product pest) inside the facility should know how to report it and what happens next. The reporting procedure, the investigation, and the corrective action all need to be documented.

Pest Control Contractor Documentation: If you use a third-party pest control company, retain their service reports, which are documentation of your pest control program. Their reports should note inspection findings, any evidence of activity, and treatments applied.

Physical Exclusion Measures for Cricket Facilities

Doors: Self-closing door mechanisms on all exterior doors prevent doors from being left open. Door sweeps seal the gap at the bottom. For high-traffic loading dock doors, consider an air curtain above the entrance.

Rodent exclusion: Seal any gap larger than 1/4 inch in the building envelope. Rodents can enter through surprisingly small openings - check where pipes and conduit enter the building, where walls meet the floor, and around any utility boxes.

Stored product pest exclusion: Grain beetles, flour beetles, and similar stored product pests are attracted to cricket feed. Store feed in sealed, pest-resistant containers or in a dedicated feed storage area with its own exclusion measures. Inspect incoming feed for signs of stored product pest activity.

Moisture control: Cockroaches and rodents are attracted to water sources. Fix leaking pipes, eliminate standing water, and ensure drains are properly sealed.

Documentation for FDA Compliance

Under 21 CFR Part 117 (FSMA GMPs), pest control is a required sanitary condition. FDA inspectors will look for:

• Evidence of a written pest control program or procedure
• Pest control monitoring records (bait station inspection logs, pest sighting logs)
• Evidence of corrective action when pest activity is detected
• No evidence of active pest activity in production areas

Keep at least 2 years of pest monitoring records. If you use a contractor, retain all service reports.

Frequently Asked Questions

Does FSMA require a written pest exclusion plan for a cricket flour facility?

FSMA's GMP requirements (21 CFR Part 117 Subpart B) require that food facilities take effective measures to exclude pests from food processing areas and to protect food from pest contamination. While FSMA doesn't specify a "pest exclusion plan" document by name, FDA inspectors expect to see a documented pest control program including monitoring records, pest sighting logs, and evidence of corrective actions. The absence of written pest control documentation is a common GMP observation in FDA facility inspections. A written plan, even a simple one-page procedure with an attached monitoring log, is the standard way to demonstrate compliance.

How do I document my cricket farm pest control program for FDA?

Your pest control documentation should include: a facility map showing pest monitoring device locations, a written procedure describing your exclusion measures and monitoring schedule, a bait station inspection log showing monthly inspections with dates, findings, and any corrective actions, pest sighting reports for any incidents with the response documented, and pest control contractor service reports if you use a service. Keep all records for at least 2 years. During an FDA inspection, have this documentation organized and accessible - the ability to quickly produce records is itself evidence of a functioning program. Keeping a designated pest control folder (physical or digital) is good practice.

What pest control measures are required in a cricket flour processing facility?

Required measures under FSMA GMPs include: exclusion at all entry points (self-closing doors, sealed gaps, screened vents), perimeter rodent bait stations with documented inspection, pest monitoring inside the facility (glue boards in non-production areas, visual inspections of production areas), and documented corrective action for any pest sightings. Chemical pesticide application inside cricket production areas is not possible without contaminating your product, so exclusion is your primary tool. In processing areas (post-harvest), limited pesticide applications may be possible if timed between production runs with adequate cleaning before resuming production - consult with a pest control professional who understands food facility requirements before applying any pesticide in a processing area.

How do I prevent pathogen spread between bins during an outbreak?

Physical separation is the most effective immediate step. Move affected bins to a quarantine area if possible and establish a strict clean-to-dirty workflow so anyone handling a quarantined bin does not proceed to clean bins without changing gloves and sanitizing footwear. Shared equipment such as scoops, scales, and thermometers are common transmission vectors and should be dedicated per bin or sanitized with a 70% isopropyl alcohol solution between uses.

Are there any approved treatments for sick cricket colonies?

There are currently no approved antiviral or antibiotic treatments for cricket colonies intended for food consumption. Management of disease events relies on quarantine, early termination of affected bins, thorough disinfection, and biosecurity practices that prevent reintroduction. For non-food-grade feeder cricket operations, some producers have experimented with supportive care (optimizing temperature and feed), but evidence for efficacy against viral pathogens like AdDNV is limited.

How long should new crickets be quarantined before joining the main colony?

A minimum of 14 days is the standard recommendation for new Acheta domesticus stock. Keep quarantined crickets in a completely separate space with dedicated equipment and observe for any signs of disease or abnormal mortality during that period. Some operations extend quarantine to 21 days and do a population health check before clearing the incoming stock. The cost of quarantine space and time is small compared to the cost of an AdDNV introduction to your main production area.
