I don’t have any good ideas and I’m interested to see what others say.
I do have one neighbor who has her yard sprayed periodically, but I don’t know anything about the pesticide used. I wasn’t so much concerned about the food for the birds as I was about potential direct harm to the birds. However, we each successfully maintain a nest box and nesting bluebirds.
Only thoughts I have are reaching out to groups like the Audubon Society – you may even have a local chapter – and your state’s Bluebird Society, if you have one. At least, perhaps find likeminded people and go from there pooling ideas and efforts.
