Scarecrows? Mylar tape? Netting? It depends on how big the area is as to what might work best........

I treat for earworms and seldom have bird damage. When I have had a major earworm Grackles and Blue Jays come in mass. For a back yard patch, putting a small plastic bag over the ear works. You do have to been care full with timing. Pollination must take place before covering.

I am having trouble with birds these days pecking on the ears when ripe. I am using footies slipped over the ears when the ears are starting to fill. What are footies? They are short nylon hose.

Thanks! It is getting pretty bad. I hung some aluminum foil around the perimeter.
