We have recently moved house and have inherited a beautiful mature garden with a teeny tiny pond. My guess is that it is an old shallow butlers sink, that fills with rainwater. We did have a resident frog, although we haven't seen him for a couple of months. This last week, it is absolutely teeming with mosquito larvae and without a frog to eat them, I am terrified they will hatch and we will have a mosquito infestation. Emptying the 'pond' would seem like the most obvious option, and filling it with soil and plants, but it has no drainage holes and I fear that drilling some in would shatter the ceramic. I'm guessing without drainage, every time it rained, they'd get very water logged. What do we do with it?? Put fish in it and hope they eat mosquito larvae?? I'm worried the 'pond' is not deep enough for the fish to find shelter from the elements/birds. Sorry to ask such a ridiculous question, but I just can't seem to think of any bright ideas!
