Haven't had the problem (they instead helped me out by eating a wasp nest once) so I am guessing. They do have a good sense of smell so perhaps something pungent, for example wood vinegar smells of smoke. Cats hate citrus perhaps badgers do too?!
Or you could try the trick of scattering some chilli pepper where they are digging?!
Thanks, will try to find some smelly deterrent. Apparently male human urine should also work. We often use grapefruit peal to attract Spanish slugs, so maybe it could double as a badger deterrent .
Yeah I would try those first. Orange essential oil and some soap is cheap though and way more pungent than some rinds. You can use it to contact kill bugs too if you need to....also important to realise if you have some beneficials flying around.
