I have determined that if you pump a Blood on the Microphone or Liberal Grouch podcast to a wireless speaker outdoors, it drives away all animals, even down to insects. There is no bird poop on my deck, and there are no rodents after my vegetable garden.
But there are downsides. It only keeps animals away as long as it’s playing, so you have to shut it off if you have a dog you need to let out or if you want to use the grill. Some people, their ears bleed, some, their bowels go to liquid, others projectile vomit. It’s worse than bird poop.
And if you play it too loud your garden will rot, so be very careful.
It may be worth it, but that’s up to you.
