Get mosquito dunks. They are safe for finned, and other friends, and deadly
to mosquito larvae.

I have a small ornamental pond (500 gallons) and there are mosquito
larvae in it. I DO NOT want to use fish as larvae control so need to
know about chemical treatments. The pond serves as a large water dish
for my six cats so I need something which kills the mosquitos, but is
safe for cats. Any proven suggestions?
