When you have unwanted visitors to your bird feeders, often a baffle will give you some relief.

If squirrels and chipmunks are running up your pole or post, we have baffles that will stop them in their tracks.  One type of baffle is cone shaped and fits most poles.  The cone spreads out at the base to prevent the squirrel/chipmunk from continuing their trek up to the feeder.  

The second design looks like a large stove pipe that attaches to the pole or 4x4 post, long enough and slippery enough to cut any traction and stop the trip to the top. This style, if needed on a pole, can only be attached to a straight pole, not one with a curve at the top that cannot be removed for mounting.  Longer larger models are also available to work with larger animals, like raccoons.
