Like Cindy said, get some Mosquito Dunks. You can get them at Lowes, Home Depot etc. I take a pair of scissors and cut off bits and stick them in the drain trays under my plants in the greenhouse and anywhere where water might accumulate. I also use about a quarter of a dunk in all of my watering cans. Problem solved. It's a biologic control .. not a poison/chemical - Bacillus thuringiensis israelensis - a naturally occurring soil bacteria.
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
