§              To prevent damage under eaves, lightweight nylon or plastic netting can be attached from the overhanging eaves to the siding of the damaged building. To keep the birds from reaching through the net, leave at least three inches between the net and the siding.

§              Aluminum flashing can be used to cover existing holes or to line the corner or fascia boards of the house. You can paint it to match your siding.

§              Setting up a suet feeder in your yard may draw the birds away from your house. Keep the feeder supplied with food throughout fall, winter, and spring when natural food is scarce and the birds are hungriest because of the cold weather. Remove the feeder, or switch to suet dough,  during the hot summer months because the suet may become sticky and adhere to the bird's plumage. Suet dough melts at a higher temperature.

§              To dull the sound produced by drumming, place padding behind the area where the bird is drumming.

§              Nesting or roosting woodpecker problem

§              As long as a nest is not already established, existing holes should be plugged with wood putty. If the birds already have eggs or young, the holes can be sealed after the nestlings have fledged, usually by midsummer. The preventive measures outlined under General Woodpecker Deterrents, can then be followed to keep the woodpecker off your house.

§              If there are long trenches and holes on the wood fascia boards of your house, chances are you've got carpenter bees, and the woodpeckers have discovered them. To discourage the woodpeckers, you must get rid of the bees.

§              Carpenter bees prefer to drill into either natural or stained wood. If the wood is painted (oil base or polyurethane), there is less chance of infestation, because a hard finish deters bees.

§              If you prefer natural or stained wood, spray the area with a preventive insect control such as Cypermethrin.

§              If the bees are already established, consider using an insecticide specifically designed to control wasps and bees. It should be sprayed into the entrance holes in late evening or at night when the bees are inside the tunnels. After 24 hours, plug the tunnel entrances with a cork, wooden dowel, or wood putty to keep bees from recolonizing there.

 If your house is sided with grooved plywood, painting it will often seal core gaps, preventing insects from tunneling into the wood. If you don't want to paint your house, caulking along the sides of the vertical grooves can cover en- trances to gaps in the core. This is labor-intensive, but it is often the only way to get rid of the insects. Once the gaps are caulked, the damage should be repaired so old holes don't attract foraging woodpeckers.

For houses sided with wooden shakes, shingles, or board and batten, the most effective remedy is probably to get an exterminator to spray the outside of your house with insecticide and then replace the damaged shakes or boards. If damage is continuous and extensive, an electronic distress call system may be effective.

Yellow-bellied Sapsuckers tend to drill for sap in certain ornamental trees, such as the mountain ash. To keep sapsuckers from damaging trees (boring rings of small holes around the bark of the trunk or limbs), wrap a burlap bag or other heavy material around the damaged area. Or you could allow the woodpeckers to use the damaged tree in the hope that they will not move to other trees. Keep in mind that sapsuckers; tend to drill into trees that are already diseased or damaged.

One common complaint from homeowners is the roosting of pigeons on their new roofs. Aside from the aesthetics, the corrosive leftovers can destroy such a roof in short order. We recommend mechanical exclusion over chemical or fatal controls. In the Tri-Valley, we have Band-tailed Pigeons, which are protected, as well as Rock Doves. They act the same and are difficult for the unpracticed to distinguish in the field. For those and other reasons, it is better not to trap or kill them. A cursory search of the Web revealed the link below. This company manufacturers of combs one mounts on probable perches to discourage birds from landing. (We searched for "Bird Control")

It would be wise, probably, to consult a professional to help find the most effective solution for your situation. Our local telephone yellow pages have a heading, Bird Barriers, Repellents and Controls, where several firms are listed.
