I have made a mixture of honey and cayenne pepper, or pancake syrup and cayenne pepper and put it on my bird feeder. The honey or pancake syrup makes the cayenne sticky. It has been very clear that the squirrels do not like the smell of the cayenne, they go to the feeder and then scamper away! It has to be replaced every couple of days or after rain.
