I'm jealous, I want an outdoor pond! Do you have a hard time keeping it full? Do you fill it with rain water, or well water?
Are mozzies, mosquitoes?
We do have those, and there is a natural control I have used, it is a spray and you must have a state license here to use it.
It's called a biological Larvicide, the active ingredient is:
bacillus thuringiensis - species- israelensis - strain 65-52
It is a "nematode" that attacks mosquito larva. Works like a charm.
But why have a pond if you weren't going to keep fish!
