Help with winter sparrows

UGH! I am enjoying soooo many chickadees, purple finch, titmice, nuthatches, doves, cardinals, and several kinds of woodpecker at my winter bird feeders. However I am also feeding way too many sparrow. I don’t really want to take the feeders down, for the other birds. But the sparrow have been jumping all around my bluebird box which last summer had two successful brood. Trapping isn’t working (I’m only catching purple finch). Is it better to stop feeding all together or …? Thanks -
