Well, if the squirrels already question your sanity, seeing forks on the garden will confirm their doubts.😜
They'll move to a "safer" neighbourhood in which to raise their younglings 😆
I hope it works for you, or that you find another solution. (I cannot think of a reason for plastic forks to scare away squirrels 😞)
Those plastic forks might be valuable collectors items in Europe soon 😉(the EU is planning a ban on plastic utensils to saveguard the oceans, though I still wonder how they'll make the plastic lobby eat their hats and accept it 😅)
