1. Use Hermetic Grain Storage Bags (Airtight Bags)

Hermetic storage is one of the most effective and affordable methods for small-scale farmers. These are airtight bags made from special plastic materials that prevent air, moisture, and insects from getting in.

Benefits:

• Protects against insects and rodents without needing chemical preservatives
• Maintains grain quality for long periods
• Easy to use and transport

How It Works: Once grains are properly dried and placed in the bag, the airtight seal limits oxygen, which suffocates pests and prevents mold growth. Brands like PICS bags and Super-Grain bags are popular options.

How to use it:

• Always dry your grains well before sealing
• Store the bags off the ground to avoid moisture absorption
• Inspect the bags regularly for tears or holes

• Easy to construct using local materials
• Low cost for small volumes

How It Works: The grains are stored in a slatted wooden or bamboo structure that allows air to circulate. The crib is raised on stilts to keep rodents out.

How to use this method:

• Regularly check for leaks or damage
• Place in a shaded but breezy area
• Use wire mesh or guards to block rodent access

 

 

3. Making use of the Metal or Plastic Silos as grain storage

For those looking to invest in longer-term storage, metal or plastic silos are a great option. These airtight containers can hold larger volumes and are ideal for group or cooperative storage.

Benefits:

• Durable and pest-proof
• Suitable for both individual and group use
• It can last many years with good maintenance

How It Works: Grains are loaded into the silo through a top hatch. When sealed, these silos protect against insects, moisture, and rodents.
