Natural squirrel repellent for the garden that won't harm the chickens?
The squirrels are absolutely demolishing my tomato plants this year. They take one bite out of every tomato and move on to the next one. I've lost probably 30 tomatoes already and it's only June.
The challenge is I have free range chickens that roam through the garden area during the day so whatever I use has to be safe for them. No poison, no traps that could grab a chicken foot, nothing that would contaminate the soil the chickens scratch in.
So far I've tried:
Cayenne pepper sprinkled on the soil around the plants. Didn't do anything. Squirrels don't seem to care.
Motion activated sprinkler. Works great when it works but the chickens set it off constantly which wastes water and annoys me.
Netting over the tomato cages. Helps somewhat but squirrels are determined and they find gaps.
I have some bugmd pest defense spray that I use around the coop for bugs and I'm considering spraying it around the garden perimeter to see if the scent deters squirrels but honestly I doubt it. It's made for insects not mammals.
Has anyone found a natural repellent that actually keeps squirrels out of a garden without affecting poultry?
