So I heeded all advice and cleaned my 6 swallow boxes and 2 Bluebird boxes.
I put up the Bluebird boxes with high hopes 2 years ago but no takers except the Greenbacks last year in one.
Most of the swallow boxes (5) were still clean from last year.
One swallow box had one nest atop another.
One Bluebird box had a swallow nest.
Up until 2 years ago I got swallows in all but one of the swallow boxes.
any clue as to what more I can do?
