Can I stop birds from building nests
on my house?
Birds find all kinds
of places on houses to build their nests. The porch
light fixture is a classic example. It's elevated,
stable and flat on top--perfect for a nest. The
best prevention for this is to change the flatness
on top. A forty-five degree slope will make it an
unbuildable site for birds. Another way to stop
nest-building is to attach a vertical mesh barrier
to the spot.
