Almond Storage, Warehouse Fumigation & Export Protection

California produces the majority of the world’s almonds. From orchards to handlers and export warehouses, protecting stored almonds from insect infestation is essential for export compliance, food safety audits, quality assurance, brand protection, and market access.

FSS provides almond-specific pest management services tailored to California growers, handlers, storage warehouses, and exporters.

Common Almond Storage Pests

Identifying the pest species is critical. Some insects respond differently to protectants or fumigation programs, and resistance management must be considered. Below is a list of common pests to which almonds are vulnerable.

Warehouse & Structural Fumigation for Almond Facilities

When infestations are present, structural fumigation may be necessary to eliminate 100% of pest pressure. 

FSS supports almond operations with: 

  • Phosphine fumigation for warehouses 
  • ProFume® fumigation for time-sensitive structural treatments 
  • Trailer and container fumigation 
  • Monitoring and documentation 
  • Compliance-focused execution 

Fumigation penetrates pallets, stacked product, and hard-to-reach voids — areas where surface treatments or fogging may not provide full control. 

For export-sensitive operations, full structural reset can prevent: 

  • Shipment rejection 
  • Audit findings 
  • Cross-contamination between lots 

Trailer & Container Fumigation

For inbound or outbound almond shipments: 

  • Enclosed semi-trailer fumigation 
  • Container fumigation at certified facilities 
  • Documentation (FMPs and clearance records) 
  • Temperature considerations (warming when required) 

Treating product before warehouse entry helps prevent infestation from spreading to larger storage areas.
