High squirrel populations also can affect commercial nut production, especially walnuts and pecans. Squirrels sometimes dig and eat flower bulbs and newly planted seeds. 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.
Shooting is effective where local laws permit the discharge of firearms.
Hunting can be a useful method to control squirrel numbers, but adequate hunting pressure is essential. Attach the collar with encircling wires held together with springs to allow for tree growth. Trees adjacent to buildings should be trimmed to prevent squirrels from jumping onto roofs. Slit the plastic pipe lengthwise and place it over the wire. The pipe will rotate with the weight of the squirrel, causing it to tumble.
