County Mosquito Control Project is committed to protecting pollinators. Since 2007, the State Reclamation and
Mosquito Control Board has instituted a policy to protect bees (SRMCB bee policy) which
PCMCP follows. As part of this policy,
we do not apply adulticides when bees are active. Adulticides are applied between ½ hour after
sunset and ½ hour before sunrise.
not use any neonicotinoids in its program.
The adulticide used in our program contains two pyrethroids. Environmental testing was done on one of
these chemicals in 2010 and 2012 did not find any residuals after aerial
spraying. (2010 report and 2012 report).
However, to further protect hives we encourage beekeepers to register
their properties as no-sprays. This
allows us to identify properties where hives are present and turn off sprayers
when we are near beehives. If you move
your hives during the summer you need to tell us so we can update the database. For further information on the no-spray list
please follow the link on the left.
beekeepers want the opportunity to cover their hives when we are adulticiding, spray routes for the
following day are publicly available after 5pm and the phone number is posted
on the Home page.
