I'm sure that this topic has come up before, but ......has anyone found a fox deterrent. The little blitters want to dig holes in my raised beds - I am netting everything but the courgettes are straining at the netting and I can't face taking the netting off and coming back the next day to find the whole lot dug up. And No, I can't face spending all night down there guarding them either!!!! Any ideas would be very gratefully received!
