Squirrels
Gray squirrels are among the most commonly observed animals. They
can be found in residential areas in almost any town or city. Generally
squirrels are non-intrusive – they are a pleasure to observe and here
in Sonoma County rarely present a problem due to high populations.
Food Attractants
Conflicts can occur when humans and squirrels live in close
proximity. Squirrel feeding can result in the loss of sweet corn,
tomatoes, and other vegetables from your garden. High squirrel
populations also can affect commercial nut production, especially
walnuts and pecans. Squirrels sometimes dig and eat flower bulbs
and newly planted seeds. Bird feeders also attract squirrels. Squirrels
are very clever problem solvers, known for feats of skill and dexterity
that amazes humans.
Occasional Problems Caused By Squirrels
When squirrels enter homes, they can become destructive because of
gnawing habits and collections of nest materials. Exterior siding
and wiring sometimes is damaged by their gnawing. In addition the
clatter of squirrel movements within the structure can be bothersome.
How To Keep Them Away
You can prevent squirrels from climbing isolated trees and utility
poles by encircling the poles with a two foot wide collar of smooth
metal six feet above the ground. Attach the collar with encircling wires
held together with springs to allow growth. Trees adjacent to
buildings should be trimmed to prevent squirrels from jumping onto
roofs.
Squirrels can be prevented from traveling on wires by installing
two-foot sections of lightweight, 2- to 3-inch-diameter plastic pipe. Slit
the pipe lengthwise and place it over the wire. The pipe will
rotate with the weight of the squirrel, causing it to tumble. WARNING: due
to the danger of electrical shock, this should only be attempted by a
qualified electrician or a representative from your utility company.
Squirrels can be excluded from buildings by closing all openings with
½ inch wire mesh or by making other necessary repairs. However,
care must be taken to ensure that no squirrels are unknowingly kept
inside the building. They would die if trapped inside an attic. If
it isn’t possible to remove young squirrels, exclusion efforts should
be delayed until the young have matured.
Naphthalene (moth balls) temporarily can discourage squirrels from
entering attics and other enclosed areas. Supplement this method by
lighting the attic. A house cat may further discourage squirrel
activity.
