How to Freeze Bird Seeds

Freeze and properly store store-bought bird seed to prevent infestation.

The best reason to freeze bird seed is to prevent or stop an infestation. Bird seed, when sitting in storage is particularly susceptible to contamination from Indian meal moths. These moths lay their eggs in bird seed. When their larvae hatch, they feed on the seed. Freezing temperatures will kill any eggs or larvae currently in your seed supply. To prevent another infestation, store your bird seed in sealable air-tight plastic or glass containers.

Things You'll Need

• Freezer bags

Instructions

1. Scoop the bird seed out of the bag and into individual freezer bags. Fill each bag to the brim and then seal it shut.

2. Place the bags in the freezer (a deep freeze is ideal) for 48 hours.

3. Take the bags out and allow the seed to return to room temperature.

4. Freeze the seed again for another 48 hours. According to the Colorado State University Extension Service, this freezing and thawing cycle will increase the effectiveness of the cold treatment.

Tips & Warnings

• Indian meal moths won't stop at bird seed. All of the grain products of your home are at risk, especially if the infestation originated in your home. Sweep out your pantry (especially the area where you stored the bird food) to remove any moth eggs that may have been laid there.

• If you see active moths, set flour moth pheremone traps (available at many home and garden centers) to catch them.
