Flipping birds constantly digging up my pots! Back garden completely paved over so I grow everything in pots but the birds are such vandals testing out plants so they can poke about with their bloody beaks! Any suggestions to how I can deter them?
yankee - they don't land on them! Magpies have incredible eyesight. They see the sticks and are put off from going anywhere near the pots. (It's the spacing, not the sharpness that does it - I actually tend to use bits of twig that I've pruned off things - they work just as well).
Same thing works for cats pooing in newly sown beds. (And I have a cat myself whom I'd never injure. He takes one look at the sticks and slopes off to find a better place).
I was thinking more about the cats. I was on a forum where someone suggested kebab sticks and a vet or veterinary nurse replied saying that they were very hazardous and can cause injury to cats in particular.
