It's my understanding that it's the way males mark their territory. They're definitely not after insects in the wood because there aren't any in the siding or trim. We're surrounded by trees, too. Cedar is soft which is probably why they...'re drawn to it. It's a lot easier than working on oak, ash, or maple. I have a lot scrap cedar and I may try hanging some pieces on the side of the house, where the feeders are, during the fall when they like to go on the attack. I'll create convenient perching conditions, too.See More
