Freezing pollen

Freezing pollen immediately after collection is the most effective method to kill pollen moths, beetles, and their eggs and larvae. Freezing pollen at temperatures below freezing for 48-72 hours eradicates pests and preserves pollen freshness and nutritional value. Frozen pollen should be stored in airtight containers in a freezer for long-term preservation. Freezing is a reliable and non-chemical method for ensuring pest-free and high-quality stored pollen. Access to a freezer is required for this method. Freezing is particularly recommended for long-term pollen storage.
