To be honest , Kevin , when approached by one of these little buggers I do not have to time to communicate with it and make pleasant conversation as to where it is from. - Our food is their food so they will, however do what they have to do and get at it , at our expense.
So.... we let them exist , alongside us , and pick up a few scraps of cat food plus the odd fly which we swat. (them not us!)
But..... sting me once , matey and I'll bite yer head off!!!
Cheers
Negg
