  Mosquito Control in Outside Water-filled Propagation Trays
From: PTOWEN7844 at aol.com on 1997.06.16 at 07:47:13(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.

25 years ago, in my college days, I worked for the City of Virginia Beach
in mosquito control. We raised and released mosquito fish - Gambusia sp?
They were very effective in controlling mosquitos in shallow, seasonally
filled depressions.

I have also use common guppies from the pet store. Both fish are effective
if algae and other food is available in addition to larvae. I have seen
Gambusia flourshing and reproducing in water filled ruts in dirt roads.

Park,

I believe it's called window screening. Comes in non-rust plastic in roll
form as narrow as 2' and as long as you like for peanuts per foot. A
couple of clothes-hanger-wire bent into hoops will complete the tent. A
brick or other fastener at the edges will hold it in place.

If they can't get in, they won't lay eggs. And even if a couple do, the
maturing larva can't get out.

Otherwise, make the troughs deeper and get gold fish.

Put a drop or so of detergent in each tray every so often. The mosquito
larvae will drown.

for such a small area that you are discussing... how about a drop or two
of some type of insecticide... That's the way I do it....
