(2) Mosquito Control: Efficacy of Backyard Applications of Pyrethroids

Is there a source for this? I'm not sure if its a journal article,
conference abstract, or something else. Thanks...Bryon

Subject: Do Backyard Mosquito Sprays Work?

Summary:  Treatment of residential backyards with pyrethroid
insecticides to suppress mosquitoes
Both Aedes and Ochlerotatus were strongly suppressed by pyrethroid
from mist blowers for up to six weeks after treatment.
However, the fact that there was no significant effect on the Culex
mosquitoes is troubling because these are the primary vectors of many
important diseases, including those that most concern homeowners,
such as WNV... therefore, the lack of Culex control in our study was
probably due to Culex mosquitoes not contacting the treated surfaces.
Culex mosquitoes may have resting sites are higher in the tree canopy
or on structural surfaces.  If pyrethroid were applied to tree
canopies or possibly other surfaces, better Culex control might have
been
observed
