How can I identify your vector control technicians?
Our vector control technicians wear a uniform with the District
name clearly visible on the shoulder patches, and upon request
can show their District badge and ID. Laboratory staff may work
out of uniform when conducting disease surveillance activities,
but will have a District badge and ID.
To get to know the technician(s) and other staff who work in your
area, visit our staff profile pages.
If West Nile virus is detected in the community, the District’s
initial response will be to intensify its efforts to locate and
reduce mosquito breeding sites, increase its levels of
larviciding in those areas in which West Nile virus has been
found, and increase trapping of adult mosquitoes for disease
testing. Reducing the adult mosquito population with pesticides
(adulticides) registered by the US Environmental Protection
Agency (EPA) will be done if necessary to prevent human illness
or to suppress a heavy nuisance infestation of mosquitoes.
West Nile Virus is a mosquito-borne virus that originated in
Africa. It first appeared in the United States in 1999 and it
moved West until it reached California in 2003. It is present
throughout the year, although illness is often associated with
peaks during hot summer months.
Zika virus has been in the news often recently,
and District staff members have received many questions from the
family, friends, members of the public, and the media. Here are a
few of the most common questions, and their answers:
When outdoors in areas where there may be ticks, wear long
pants and sleeves. Don’t wear shorts, sleeveless shirts, or
sandals. Tuck pants into socks or boots, and shirts into pants.
Light-colored clothing makes it easier to see ticks before they
attach to the skin.
The insect repellents that work for mosquitoes are effective
against ticks. Look for formulas containing DEET. These should be
applied according to the label instructions only.
What’s the difference between yellow jackets and bees?
Yellow jackets feed on other insects as well as nectar, while
bees feed only on nectar. Bees can only sting once while
yellowjackets can sting multiple times. Yellowjackets have black
and yellow stripes and shiny bodies while bees are fuzzy and
brownish. Bees typically build hives in hollow trees high above
the ground. Their hives contain wax combs. Yellowjackets build
round paper nests either under the ground or hanging from tree
branches. Bees produce honey and feed on nectar and pollen from
