Mosquito Control in Outside Water-filled Propagation Trays

From: PTOWEN7844 at aol.com on 1997.06.16 at 14:47:13(847) Does anyone have any practical advice (based on experience) on how to control mosquitos in shallow trays used outside to propagate bog and other moisture-loving plants and not "kill" or "damage" the emerging seedlings or more established plants. I keep the water depth fairly shallow (0.5" to 1") in my propagation trays which are plastic-lined wooden boxes 2' x 8' x 3". I keep the plants in these boxes for several months, which coincides with the height of mosquito season. With no circulation or aeration of the water, the mosquitos have been quite prolific! Is there any "seedling friendly" product that would be effective against mosquitos in this situation? Any other suggestions on low-cost equipment to propagate these plants outside other than in water-filled trays? My mosquito-bitten neighbors and I will be eternally grateful for a solution. Park T.
