All over the patio (unsightly), over the garden furniture and table (unhygienic) and over the climbing frame and swing where my lo's put their hands (argggh!)
I had to chip a hardened bit of bird crap off the swing the other day with a trowel and then follow this up by pouring boiling water over it to soften it and get the rest off.
I don't want to get a cat (because I am allergic and I live on a main road so it would be a squished cat). Any other ways to deter the little f*&^wits?
