I watched them yesterday, in between faffing about. I don’t think that there is any way of keeping them out. We have a hedge and fence and next doors drive between us and the little bit of woodland. Our hedge is quite long and has a huge choice of entry points for them. The combination of barriers is very efficient at keeping the deer and rabbits out so they are safe.
I’m out all day today, having a break from faffing?. I expect DH will get the gun out.
Sorry Lynne, hope you aren’t lurking!

, I had to stop feeding the birds here because of rats , not fond of them either Lynne , sorry ! Glad you are ok Pamela 
, I was not a fan of squirrels since they ganged up on me in the Botanics , about 51 yrs ago , looking for food round my feet , then one dropped to my shoulder . The fire Brigade were nearly answering my shrieks , I will try and shut up now xxx
