5 Piece Feeder Pole Set with Twist In Ground Socket

Glad you like the Erva pole set!  Yes, squirrels readily climb poles and shepherds hooks.  You might consider purchasing one of the shippable squirrel baffles we carry--links are below: https://nature-niche.com/products/dome-top-squirrel-baffle-and-squirrel-guard  https://nature-niche.com/products/squirrel-baffle-squirrel-guard  Be sure to read and execute the other safeguards to keep the squirrels off, including placing the top of the baffle at least 4' above the ground surface (squirrels are good jumpers!) and locating the pole system at least 10' from lateral or other launching points like tree limbs above the feeder.  If you don't mind feeding them, providing an easily accessible squirrel feeding station away from your bird feeder may also reduce feeding pressure where you don't want them.
