Have you considred building bat houses? Environmentally friendly,
affordable, and feuled by mosquitos... Bats eat a thousand mosquitos
a night, and are rumored to be much more effective than birds at
eliminating mosquitos (as they don't eat as many dragonflies). All
you need is a reliable water source for them and some cedar, and some
non-squeemish family members. Apperently they also eat some of those
grub-laying beetles that ruin you lawn.

Bats carry some pretty lethal diseases.

Bats eat a thousand mosquitos a night, and are rumored to be
much more effective than birds at eliminating mosquitos (as they
don't eat as many dragonflies). All you need is a reliable water
source for them and some cedar, and some non-squeemish
family members. Apperently they also eat some of those

I've got nothing against bats, and wouldn't mind if there were bats
flying around my place at night (there might very well be - I don't know
- it's hard to see when it's dark out).

But it's a fallacy that bats eat lots of mosquitoes.

I have no doubt that in more tropical or sub-tropical areas, rural, lots
of standing water, marshes, etc, that there are clouds of mosquitoes
where the bats can just fly around with their mouths open and collect
dozens of mosquitoes in a single pass and repeat that several times a
minute for several hours.

But in the northern half of the US and southern Canada, in urban or even
suburban residential back yards, you're not going to have these dense
clouds of mosquites and large open flyways for the bats to swoop in with
their mouths open and collect them.

Individual mosquitoes are too small to be detected by the bat's
echo-location system, and a single mosquito wouldn't give the bat enough
calories to make the effort worth it.
