I got a cake of dried mealworms; it's sort of like a suet cake only this has no suet, just the dried mealworms. Nothing touched it. Nothing! None of the birds were interested in it at all. They adore the mealworm suet BUT I have tons & tons of bluebirds & not a single one have I seen on the mealworm suet and of course they don't eat seed soooooooooo
