How do I feed live mealworms to garden birds?

When your worms are weighed and packed here at the farm they are sent with some bedding of wheat bran. As they eat this the resulting material is called frass and needs to be sieved (a normal small kitchen sieve is perfect). Because live mealworms are a bit wiggly the key to feeding them to your birds is to use a steep sided dish so that they can’t crawl out. The ones on sale are all steep sided but they also have the benefit that you can lower the cover section which stops the rain from getting in and also means that only the smaller birds can access the feeder.
