Mealworm feeders

Mealworms bring birds that seldom eat seed, bluebirds and Carolina wrens among them, as well as chickadees, titmice and nuthatches. Offer a small amount in a dish they can see, such as the Birds Choice Bluebird Feeder, whose 1½ in side holes keep bigger birds out, and soak dried mealworms in water first.

Sheltered Mealworm Feeder

Bluebirds and other small birds, which slip in through the 1½ in openings while the roof keeps rain and snow off.

Keep in mind: Project FeederWatch cautions against wood feeders that cannot be washed well: wash it often and let it dry fully.

Who comes for mealworms

Project FeederWatch lists mealworms among the foods of bluebirds, Carolina wrens, chickadees, titmice, nuthatches, woodpeckers and blue jays. They matter most to bluebirds and wrens, which live mainly on insects: a Carolina wren eats little seed, though it comes to suet in winter, Cornell notes.

Dish, cup or roofed feeder

An open dish is easy for birds to find but lets every bird in. A cup behind 1½ in holes, as in the Birds Choice Bluebird Feeder or the Duncraft Sheltered Mealworm Feeder, keeps bigger birds out once the small ones have learned the way in. A clear roof keeps rain off, and a mesh floor, like the Songbird Mealworm Magnet’s, lets water drain.

Live, dried, and how much

Live mealworms wriggle and catch a bird’s eye; dried ones keep for months in a sealed tub. The RSPB, Britain’s bird charity, suggests soaking dried mealworms in water before you put them out, which softens them for nestlings and adds water to the birds’ diet. Put out a small amount once or twice a day, at the same times, rather than a full dish that sits.

Keep the dish clean

Mealworms and fruit spoil quickly in warm weather. Clear what is left at the end of the day, and every few days wash the dish in hot soapy water, rinse it and let it dry before you refill it.
