Anyone here have a backyard pond?

Anyone here have a backyard pond?

We transferred everything from our old pond (rocks, liner, the whole gamut)at the old house but still haven't gotten a new one dug in here yet. Meanwhile, I have two big tubs -- one of cattails, another of papyrus. The cattails stay outdoors through the winter, the papyrus I'll be moving outdoors soon. However, with the mosquito problem and the 'West Nile Virus' going around, I'm concerned about the containers with still water as a breeding ground. Any suggestions --short of getting off my butt and getting the new pond built -- about possibilities for preventing this, either some kind of plant-safe spray, or something? And aside from my question I still want to know of others who have ponds :) !
