There is no need to scare them off. All birds are naturally afraid of people. Woodpeckers are especially "flighty" and will quickly leave as soon as you come within their vision. That being said, I do suggest you install some MOVING SPIDERS but only after you treat the carpenter bee holes. This will insure your home doesn't sustain any more damage because the woodpeckers will no doubt stick around awhile since they now know your home is full of food.

At this point your strategy should be two fold. The first step will be to get some DRIONE DUST and treat all the exposed and obvious carpenter bee holes as explained in our CARPENTER BEE CONTROL article. Once treated, seal them up with the 1/2" CORKS. Next, install some of the Spiders in the same area. They'll protect the wood from further damage. If you treat well enough, the bees and larvae will all be dead within a few days. Larvae hatching over the summer will all die since the Drione will last 6-12 months when treated holes are sealed as we explain.
