What is used to stop squirrels from traveling on wires?

• A. 2-foot sections of 2- to 3-inch diameter plastic pipe split lengthwise
• B. Electrical tape
• C. Foam insulation tube
• D. Metal conduit

Answer: (A)

Preventing squirrels from moving along wires relies on creating a smooth barrier that they cannot grip. A split-length piece of smooth plastic pipe wrapped around the wire provides that barrier: the slick surface and the lack of a gripable edge make it hard for a squirrel to climb, effectively stopping travel along the cable. Using about two-foot-long sections with a diameter around two to three inches lets you cover the relevant portions of the wire and snap the pipe around without needing to thread the wire through. This method is practical, durable, and easy to install in the field. In contrast, electrical tape tends to peel or bunch, foam insulation can compress or be gnawed, and metal conduit is heavier and less adaptable as a barrier, making them less effective for this purpose.
