I have a set of trees on an "island" planning and to keep the nice micro environment they are in a large shallow pot that has water in it. This of course creates a very humid environment and encourages the trees to grow roots towards and into the water. My problem is there is a mosquito larvae in them and I am sick of dumping and refilling as it is a monumental waste of a resource.

Does anyone know of a chemical base I can add that kills or prevents larvae? IF it were deeper I would add mosquito fish as a natural method but this isn't possible.

Company called Gemblers (online www.gemblers.com) sells several types of mosquito bait for water.
I use 30 oz. Mosquito Bits for $17 plus shipping. It will kill any larva in 12 hours or less. I also use the water on my trees, garden and flowers.

From site
"Once wet, the Mosquito BitsŪ kill the immature, aquatic stage of the mosquito. Bti (Bacillus thuringiensis israelensis) is a beneficial organism that is lethal to mosquito larvae, but harmless to fish, humans and other animals. Mosquito BitsŪ kill within 24 hours. Sprinkle the bits into standing water in an old tire, pond, rain barrel, tree hole and more to eliminate mosquito larvae. 4 oz. of bits treats up to 100 sq. ft. of water surface, regardless of depth. 30 oz. USA made. "
