Thank you for all your suggestions. I think contacting local wildlife groups sounds like a good idea and possibly trying to intercept females before they reach the pond. I will certainly give it a try.
We made the pond more than 20 years ago and the wildlife just arrived. At first we had frogs, toads and newts but newts eat frogspawn so the frogs now go somewhere else. Generally speaking, it gives us a great deal of pleasure, but I do feel sorry for those poor toads - gang rape followed by murder - who needs EastEnders?
