Judith, sorry about the frozen pipes, very wise to keep lots of water on hand, hopefully the guy can come thaw them out for you and replace the insulation.
Sally, I started feeding the birds the dry meal worms last year and many of the birds do indeed eat them, I have seen the chickadees with them in their bill, the flickers, hairy and downy woodpeckers, nut hatches, house finches, Steller's jays, starlings, blackbirds during the spring and summer. I add them to the feeders throughout the year, I would definitely buy some for the bluebirds. We have the beautiful mountain bluebirds here in the spring and summer, sadly their numbers have been steadily declining.
Happy New Year, may 2022 be kind to everyone.
