Our backyard is INFESTED with mosquitos. You could walk outside at any time
of day and within 5 minutes have 10 or 20 bites. There is no standing water
whatsoever in our yard, the gutters are clean. I think we have bad neighbors
is all.

So...

We just bought the 1 quart bottle of this:

and last night sprayed it all over the backyard with a hose end sprayer. So
far so good. I went out this morning and didnt see any mosquitos.

Has anyone else had any experience with this product or products like it?
What concentration did you use? How much have you gone through? How long has
it lasted?

Interesting! Here's the patent citation (from 1998):

I have had good luck using a permethrin spray (about $10 for enough to
treat my front and back yard twice - Home Depot). The only concern is
its effects on bees so don't spray any flowers upon which they forage.
Not toxic to humans or animals as used.
