As far as killing them, you'd have to use something that would likely
make your tomatoes inedible, and it probably wouldn't be effective
for long.

An occasional spraying of Malathion if you get a real outbreak is quite
effective and breaks down within a few days...

Best thing is to remove all standing water after a rain so they have
no place to breed. Take a good walk around your property and look
painstakingly for standing water.

Hummingbirds eat mosquitoes, so put up some feeders and attract them
(www.hummingbirds.net is the best place for info). Bats eat them, too,
but I don't know if they're a favorite food! I've also heard that
purple martins eat them, so put up a martin house (those big multi-
bird house units on top of the tall poles).

Swallows are also effective if one has them...

But, best is the water-hunting, but--you can do so, but unless all your
neighbors are as zealous as you, you'll still get an infestation after a
rain and a week or so dry spell...
