Bunker Fumigation – Certified Protection for Stored & Exported Grain

Q: What pests does fumigation kill?

It targets all major grain pests, including weevils, lesser grain borers, rust-red flour beetles, and moth larvae.

What is Bunker Fumigation?

Bunker fumigation (or silo fumigation) is a specialised pest control method used to eliminate insects and pests in grain stored in outdoor bunkers. These bunkers typically hold thousands of tonnes of grain under large tarps, creating a sealed environment ideal for fumigation. This process is essential to maintain grain quality, comply with export standards, and prevent contamination from pests such as weevils, beetles, and moths.

Our Process

Here’s how we handle your silo fumigation, step by step:

Initial Enquiry: You call our team to discuss your fumigation needs.
Site Inspection: We inspect the bunker site and assess pest risks and tarp integrity.
Quote: We provide a tailored quote based on grain volume, pest load, and site logistics.
Fumigation: Our licensed technicians carry out the fumigation using DA-approved techniques.

What Are the Benefits?

✔️ Ensures grain remains pest-free and market-ready
✔️ Complies with export standards and grain buyer requirements
✔️ Treats bulk quantities of grain in a single application
✔️ Protects stored product investment during long-term storage
✔️ Delivered by DA-licensed fumigators with decades of experience

What to Expect

Once the job is booked, we arrive on-site with the necessary safety equipment and licensed gas. After safely sealing the bunker, we introduce the phospine fumigant and monitor the exposure period. Once complete, we ventilate the site and confirm safe re-entry. You’ll receive certification for compliance and peace of mind.

Some Frequently Asked Questions that we get about our Bunker Fumigation...

How long does fumigation take?

Typically 7–10 days including fumigant exposure and ventilation. The exact time varies based on grain type, volume, and site conditions.

Do bunkers need to be fully sealed?

Yes. For fumigation to be effective, bunkers must be sealed to retain the gas. If needed, we can help inspect or advise on sealing requirements.

What pests does fumigation kill?

Our phosphine fumigation targets all major grain pests, including weevils, lesser grain borers, rust-red flour beetles, and moth larvae.

Is it safe?

Yes — we’re licensed fumigators and follow strict safety procedures. Once fumigation is complete and the site is ventilated, the grain is safe to handle.
