water insecticide for mosquitos that is safe for plants?

[Jason_mazzy]

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 Bits® 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 Bits® 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. "
