Vector Control To Spray for Aggressive Mosquitoes

Posted: Updated:
 (FOX11/CNS) - Pesticides targeting aggressive Asian tiger mosquitoes
will be sprayed tomorrow in parts of Arcadia, South El Monte and an
unincorporated area north of El Monte.

The invasive species, distinctive for its black and white stripes, can
transmit dengue and chikungunya viruses and encephalitis.

Chikungunya is a painful disease that has spread rapidly in the
Caribbean and poses "a very real risk for introduction into the United
States," according to the agencies responsible for controlling  mosquitoes.

There is no vaccine or cure for dengue or chikungunya and both illnesses
are typically debilitating, with high fever and severe joint and muscle pains
lasting a week to several months.

Two agencies will use two different treatments in infested
neighborhoods. The spraying is scheduled Wednesday between 12:30 a.m. and 5
a.m.. Both pesticides target immature and adult mosquitoes.

The Greater Los Angeles County Vector Control District will apply a mist
of Zenivex using truck-mounted foggers. The active ingredient is etofenprox,
a non-carcinogen classified by the federal Environmental Protection Agency as
low risk to humans and the environment.

The San Gabriel Valley Mosquito & Vector Control District will use
VectoBac WDG in a low-volume mist. The active ingredient, Bti, is a bio-
rational larvicide with minimal risk to humans and wildlife, according to
district authorities.

As a general precaution, officials asked residents in the immediate
areas to stay insides with the windows closed and to cover outdoor fish ponds,
pet food and water bowls during the application.

The agencies also offered tips on what residents can do to stop the
spread of this aggressive, daytime biting mosquito:
   -- immediately report any small, black and white mosquitoes or any
mosquitoes that are biting during the day;
   -- dispose of containers, recyclables, cans, buckets, old tires and trash;
   -- remove water saucers from beneath potted plants and drill drain holes
in all flower pots;
   -- do not store water in uncovered buckets or rain barrels and make sure
barrels are completely sealed; and
   -- empty bird baths and small fountains completely or clean them
thoroughly every three days.

The agencies offer free mosquitofish to maintain ponds or large fountains.

Arcadia and El Monte residents may call the San Gabriel Valley MVCD at
(626) 814-9466 to report sightings or for more information. South El Monte
residents may call the Greater Los Angeles County VCD at (562) 944-9656.
