I bought some tiny sparkly metal stars to keep the pigeons out of my garden. They trample in the garden every day and damage plants. I know they don’t mean to, but I’d like them to stop. I read that sparkly things will keep the pigeons away, because the sunlight hits the bits of metal and confuses/annoys the pigeons enough that they stay away. I’ll try it tomorrow. If that doesn’t work, I’ll try spraying cayenne pepper around the garden (apparently that works too).
