Professional commercial fumigation services that protect stored goods, eliminate infestations, and certify pest-free commodities for shipment and storage. Sterling Pest Control provides comprehensive pest management solutions and pest control services to customers throughout the United States.
5 Highlights of Commodity & Storage Fumigation
- Phosphine and sulfuryl fluoride treatments — We fumigate grain bins, silos, warehouses, mills, rail cars, trailers, and shipping containers using registered fumigants like aluminum phosphide and Vikane gas. Each application follows strict concentration-time product protocols to achieve complete pest mortality across all life stages, from egg to adult. Our effective treatments maintain the quality of stored grains and commodities.
- Stored-product pest eradication — Our technicians target rice weevils, Indian meal moths, khapra beetles, lesser grain borers, flour beetles, termite colonies, ants, and other commodity-destroying insects. We also address bird contamination issues. We identify the species first, then calibrate the dose and exposure period for guaranteed results based on extensive research and experience.
- Phytosanitary and pre-shipment compliance — Sterling Pest Control issues fumigation certificates that satisfy ISPM 15 standards, USDA APHIS requirements, and international quarantine regulations. Your commodities clear customs without delays.
- Gas tightness testing and sealed fumigation — We perform pressure decay tests on every structure before introducing fumigant. Airtight tarping, gas-proof sheeting, and recirculation fans ensure uniform gas distribution and penetration throughout the commodity mass.
- Full-spectrum commodity coverage — We treat wheat, rice, corn, cocoa beans, coffee, tobacco, dried fruits, citrus products, spices, timber, cotton bales, and packaged foods. Our services extend to food processing facilities and processing plants handling post-harvest commodities. Flat storage, bunker storage, cargo containers, and ship holds all fall within our service scope.
Why Choose Our Commodity & Storage Fumigation
Commodity and storage fumigation is a regulated, high-stakes operation. One miscalculated dose or a poorly sealed structure means surviving pests, rejected shipments, lost revenue, and costly business downtime. Pest issues can cause significant financial loss and impact your bottom line. As a trusted fumigation company, Sterling Pest Control removes that risk and helps you save money.
Our fumigation technicians hold state and federal certifications for restricted-use pesticides, including phosphine-generating compounds and sulfuryl fluoride. Every team member is licensed, certified, and carries current applicator licensing. They complete annual recertification through accredited continuing education programs. We don’t assign general pest control operators to fumigation jobs. We deploy highly trained fumigators who work in stored-product entomology and gas management, bringing extensive experience to every job.
We measure twice. Before any fumigant introduction, our crew conducts a thorough gas tightness test using calibrated pressure monitoring equipment. We plan each treatment and calculate the correct dosage based on commodity type, volume, temperature, and target pest species. The best approach is used for each situation. During the exposure period, we monitor gas concentration with phosphine detectors and adjust through recirculation or top-up dosing as needed.
Sterling Pest Control provides complete documentation for every treatment. We provide thorough support throughout the process. You receive a detailed fumigation certificate, treatment records, gas concentration logs, and clearance test results. These documents include everything needed to satisfy export requirements, food safety audits, HACCP critical control point verification, and regulatory inspections.
We guarantee pest elimination. If post-treatment sampling detects live target pests, we re-treat at no additional charge.
Signs You Need Commodity & Storage Fumigation
Live insects in stored grain or processed goods: You spot adult beetles crawling across the surface of bagged wheat, or small moths flutter near warehouse lighting at dusk. Rice weevils leave characteristic round exit holes in individual kernels. Flour beetles congregate in warm pockets within bulk storage. When you discover any live stored-product insect, it signals an active infestation issue that surface spraying won’t resolve. The contamination will spread if not addressed. Fumigation penetrates deep into the commodity mass where contact-based treatments can’t reach, helping you get pests out completely.
Webbing, frass, or larvae in packaged products: Indian meal moth larvae spin silken webbing across grain surfaces and inside packaging seams. Frass – the fine powdery excrement left by feeding insects – accumulates in corners of bags, between stacked pallets, and along conveyor systems. These pests can contaminate products placed in any storage area. These signs indicate a breeding population that has moved well beyond a few stray adults. Commodity fumigation with phosphine or sulfuryl fluoride permeates every place within sealed packaging and kills larvae hidden within the product itself.
Rejected shipments or failed phytosanitary inspections: A quarantine officer at the destination port intercepts your cargo and finds live pests or pest damage. The shipment gets held, re-treated at your expense, or returned. The financial impact can be severe. Pre-shipment fumigation with proper certification prevents these costly interceptions, saving time and resources while keeping your supply chain moving.
Elevated insect trap counts in storage facilities: Your Integrated Pest Management program uses pheromone traps, probe traps, or pitfall traps throughout the warehouse. When trap counts exceed the action threshold – the predetermined number that triggers intervention – fumigation becomes the corrective measure we recommend. Spot treatments and sanitation alone won’t suppress a population that has reached threshold levels across multiple monitoring stations. An IPM approach helps maintain low pest pressure and prevent future infestations.
Commodity temperature and moisture conditions favoring rapid pest reproduction: Stored grain above 70°F with moisture content exceeding 13% creates ideal breeding conditions for grain borers, psocids, and dermestid beetles. These conditions cause populations to double in weeks. Fumigation breaks the reproductive cycle, and combined with grain cooling or aeration, it prevents reinfestation. We help improve storage conditions and ensure your facility is ready for long-term commodity protection.
Our Commodity & Storage Fumigation Process
Commodity and storage fumigation is a controlled, multi-phase operation. Sterling Pest Control follows a standardized protocol for every commercial pest fumigation job. Proper planning will make the difference between success and failure.
Step 1 — Site assessment and pest survey. Our fumigation manager inspects the storage structure, identifies the target pest species, evaluates the commodity type and volume, and measures temperature and moisture conditions. We survey the facility for structural integrity, ventilation points, and potential gas leak paths. Whether the structure is a warehouse, house, or any building built for commodity storage, our research-based assessment defines the treatment area and informs our approach.
Step 2 — Sealing and preparation. Technicians seal all openings, vents, doors, and cracks using gas-proof sheeting, sealing tape, foam, and caulk. For tarpaulin fumigations, we drape and secure tarps over commodity stacks with sand snakes or water seals, with each area being clearly marked. We then conduct a pressure decay test to confirm the structure meets gas tightness standards. This form of preparation is essential for success.
Step 3 — Evacuation and safety posting. We evacuate all personnel from the treatment zone, post warning placards and danger signs at every entry point, and establish a secured buffer zone. All notification requirements are fulfilled before fumigant introduction.
Step 4 — Fumigant introduction and monitoring. Technicians wearing self-contained breathing apparatus introduce the fumigant — aluminum phosphide tablets, magnesium phosphide plates, or sulfuryl fluoride gas — at the calculated dose. Recirculation fans distribute gas evenly. We monitor concentration levels at multiple points using calibrated gas detectors throughout the entire exposure period.
Step 5 — Aeration, degassing, and clearance. After the required exposure period, we open the structure and activate exhaust fans and aeration systems to ventilate the fumigant. We measure residual gas concentrations at commodity level and in the breathing zone. The space receives clearance only after readings read below the permissible exposure limit. You receive a signed clearance certificate and full fumigation treatment documentation. Our united team ensures every step meets the highest standards.

FAQs About Commodity & Storage Fumigation
What is commodity and storage fumigation?
Commodity and storage fumigation is an integrated pest control method that introduces a lethal gas – typically phosphine or sulfuryl fluoride – into a sealed space containing stored goods. The gas penetrates the entire commodity mass, killing all life stages of stored-product insects including eggs, larvae, pupae, and adults. It treats bulk grain in silos, bagged commodities in warehouses, goods inside shipping containers, and products stored in fumigation vaults.
When should I schedule fumigation for stored products?
Schedule fumigation when insect monitoring trap counts exceed your action threshold, when you detect live pests or pest damage in stored commodities, before export shipments that require phytosanitary certification, or when a regulatory inspection identifies an infestation. Preventive fumigation on a seasonal schedule also makes sense for facilities that store grain, dried foods, or other susceptible commodities through warm months.
How long does the fumigation process take?
The full process – sealing, treatment, and aeration – typically runs three to seven days. Phosphine fumigation requires a minimum exposure period of 72 to 120 hours depending on temperature and target pest, with the structure being sealed throughout. Sulfuryl fluoride treatments can complete in 24 to 72 hours. Aeration and degassing add another 12 to 48 hours before clearance testing confirms safe re-entry.
Can fumigation damage my stored commodities?
Phosphine at proper dosage levels does not leave harmful residues on grain, dried foods, or raw agricultural commodities. Sulfuryl fluoride is registered for specific commodity types and leaves no persistent residue. Sterling Pest Control selects the fumigant matched to your commodity and follows maximum residue limit standards set by the EPA and Codex Alimentarius.
Does fumigation require us to vacate the facility?
Yes. All personnel must evacuate the treatment zone before fumigant introduction. No one re-enters until our technicians complete degassing, ventilation, and clearance testing with calibrated gas detectors. We handle all evacuation coordination, safety posting, and re-entry authorization as part of our standard service.
How do you confirm the fumigation worked?
We verify efficacy through post-treatment commodity sampling and inspection for live target pests. Gas concentration logs confirm that the required concentration-time product was maintained throughout the exposure period. You receive a fumigation certificate documenting the treatment parameters, clearance test results, and pest-free status of your stored goods.
