Can I ask people to consider not using fake cobwebs in their gardens as a Halloween decoration. Firstly, they are really harmful to wildlife. Birds and other flying insects get caught in them and can’t easily disentangle themselves and secondly they are made out of plastics which are non biodegradable meaning they last forever.
Stick to actual pumpkins that animals can at least eat once you’re done with them.
