Produce Storage Fumigation & Food Facility Fogging

Keeping stored produce free of pests protects quality, prevents infestations, and extends shelf life. Often grouped under "produce storage fumigation," fogging disperses EPA-registered aerosol insecticides evenly through a facility, reaching airspace, cracks, seams, and concealed surfaces. It's worth distinguishing from true gas fumigation — a separate, restricted-use process that penetrates packaged product and must be carried out by a certified applicator. This page covers fogging equipment and its applications.

Produce storage treatment runs across operations of every size, from small farm stores to large agribusiness and food-distribution facilities. Professional fogging equipment supports reliable programs that help keep produce fresh, uncontaminated, and ready for distribution.

Aerosol droplets from ULV and thermal foggers are used across a wide range of stored-product applications, including foodstuffs and materials such as tobacco and leather. Thermal fogging creates fine droplets that fill a structure's airspace, while ULV foggers deliver droplets that can be tuned to stay airborne briefly or wet structural surfaces when needed.

Treatment of Empty Storage Facilities

Thorough cleaning is the critical first step for insect control. Removing dust and debris keeps insects from sheltering out of reach — peer-reviewed reviews of stored-product IPM find that poor sanitation sharply reduces the effectiveness of aerosol treatments, because leftover residues give insects both refuge and food. Once a structure is clean, exposed insects can be controlled effectively with ULV fogging.

Residual surface treatment
When residual deposits are needed, ULV foggers set to the right droplet size deliver knockdown while also wetting surfaces. ULV fogging is especially useful in structures built from materials with deep cracks and crevices — wood or brick — where treatment has to work its way in.

Treatment of Bulk Stored Potatoes

Thermal fogging is commonly used as a sprout suppressant for potatoes stored in boxes or bulk stacks. In large bulk configurations, forced air may be needed to move the fog through the stack for even coverage.

Safety consideration: where straw is used for frost protection, handle thermal fogging equipment carefully to prevent ignition — thermal foggers run hot, and dry straw is a fire risk.

Treatment of Bagged Produce & Processing Rooms

Bagged produce and food-processing rooms are typically treated with natural pyrethrins, in formulations chosen specifically for thermal or ULV application. In these spaces, fogging is generally effective against flying insects and insects on bag surfaces — but not those sealed inside packaging, which is a limit of any aerosol.

Formulations
Oil-based formulations containing at least three percent pyrethrum are a common choice. When water-based products are used, add an appropriate carrier so droplets don't evaporate before reaching the target surfaces. Always follow the product label.

Professional Fogging Equipment for Produce Storage

ULV foggers suit mold inhibitors and disinfectants in empty cold-storage areas before filling; thermal foggers, from handheld to truck-mounted, fill the airspace of larger structures. Match the unit to the facility size and the formulation.

Application note: fog only in closed structures, keep them sealed after treatment, then ventilate fully before unprotected personnel re-enter — following the product label's restricted-entry interval. Enclosed-space applications have specific ventilation and re-entry requirements under the label.

Hurricane Ultra II ULV Fogger
Produces fine droplets ideal for knockdown of natural pyrethrum-based aerosols in processing and storage rooms.

TitanFog Pro X200 ULV Fogger
A higher-capacity ULV unit that can be set to larger droplets for residual surface treatment alongside knockdown.

Mini-Pro 8HP
An engine-driven unit whose nozzle-pressure adjustment lets operators select larger or smaller droplets for knockdown or residual work; on a wheel kit it stays portable for large-scale operations.

Dyna-Jet Model L30
An electric-powered ULV fogger for facilities that need clean, emission-free operation indoors.

Thermal options: for airspace treatment and potato sprout suppression, the Golden Eagle Model 2610 (handheld) and Piston Engine Model 1200 (truck-mounted) fill larger structures with a visible fog.
