Pole Squirrel Baffles that block squirrels from bird feeders make them squirrel proof. These Bird feeder Pole Squirrel baffles block squirrel attacks from below. That is they stop squirrels from climbing up the pole. Cone Squirrel Baffles are wrap around baffles and nice to use on shepherd staff poles or 1" diameter bird feeder poles to squirrel proof the poles. The wrap around style can also be useful because the pole does not have to be disassembled to mount. The cylinder style baffles are used on 1" diameter poles or 4x4 posts. They need to be able to slip down over the pole for mounting. These baffles are very effective and do a good job. The height can be set for either style with their mounting hardware to be the most effective, usually about 4 to 4.5 feet off of the ground.
