Our bird feeder has been under attack. My husband has been trying to out-clever a clever racoon, with not much luck. First he lengthened the support. That lasted a few months. Then he added long nails sticking out of the support. That worked for a while too.
Then he added a plexiglass disk.
Now he has a camera and infrared light to see how his nemesis is getting to the feeder.
Turns out, it's really impossible to out-trick the trickster.
He'll figure out a way around anything.
The final ploy? Put hot sauce on the seeds. One taste and the racoon ran away. He hasn't been seen since.
