This is the same idea as the propane mosquito traps, that when run for a few weeks can eliminate a local population.

But the only places where they're useful is exurban, edge of the city kinds of places. Places where we've already disturbed the local ecosystem so much that the populations aren't kept in balance. Otherwise your other environments don't need them:

- a place where they're spraying so many pesticides that nothing survives, ie most cities

- a place where the bats, barn swallows and larval predators are so plentiful mosquitos are kept in check.

- a place where there are seasonal swarms of small bugs you simply cant put a dent in. people tend to visit these in-between seasons.
