Does anyone know how to dry them easily September 5, 2018 at 1:20 pm #4180 Adam BanksModerator Hi – the 4 most common methods for drying insects are dehydrating, oven drying, microwave drying and freeze drying. For bird feed I doubt that freeze drying would be an economical option though. Author Posts You must be logged in to reply to this topic.
