Diving Beetles

I have a new wildlife pond only about 3mths old. It is roughly 11ft x 7ft x 2ft deep. Well planted and now is infested with Giant Diving Beetles. I dont have a problem with them being there but they are reaching plague proportions with the pond now full of their larvae. I really had hoped many other species would have moved in giving a better balance. Should I remove some of them or leave it to reach its own balance through time. I believe the beetles are voracious feeders so will new species get a chance to develop.

Giant Diving Beetles (Dytiscus marginalis)are fierce beasties and so are their larvae which are known as "water tigers" They will certainly attack fish, frogs, tadpoles and anything else that moves. Best way of reducing the population is to wait before putting anything edible in your new pond. Frogs and newts make take a year or so to find it and if you don't put any fish in, then the beetles will have to go elsewhere for dinner. Is there another pond nearby where they are coming from? If so, you may never get rid of them. Personaly, I would just leave them, the newts and the frogs to sort a balance out betwen themselves and forget all about stocking your pond with goldfish or other aliens. You will have a much more interesting pond without them. Goldfish eat all the tadpoles too and you need them to grow into frogs to keep down your slug population. It's all about balance.
