Woodpecker hole on your chimney?

In our annual meeting yesterday (thanks to those that attended!), one item that came up was the woodpecker/chimney nuisance.  Several homes have woodpeckers that are blasting away at holes, usually on chimneys.  Turns out that the woodpeckers are simply after the carpenter insects – bumblebees or wasps – that originally created the hole.  One resident recommended PMSI (Pest Management Services Inc) who will get rid of the insects and patch the hole.
