Best insecticide for adult mosquitos????
 

We live in a semi-rural area - houses 100 yards or so apart - and
have a serious problems with mosquitos bedding down around the house in
shrubs, etc. There's a row of holly next to the garage, for example,
if you agitate it with a stick, HUNDREDS of mosquitos come pouring out.
They're also collecting under our deck, and a couple of other places.

I tried spraying the holly very thoroughly, inside and out, with a
general purpose insecticide from Home Depot - Sevin. It had NO effect
on the mosquitos. What can we spray these places with to kill them?
How about malathion? And please, bunny-huggers and anti-pesticide
loonies, don't bother..

Thanks
