|We have several crews
during the season doing various tasks to monitor and control mosquitoes
throughout our District. Maybe you have seen them working out in the
field?Each seasonal employee is assigned to perform certain tasks, here
is a glimpse into what we do to control mosquitoes. Included with each
area is a link to request services, if available.
Please double check
before submitting a request that you live within our boundaries, particularly if you live in West Valley or north of 3300 South.
Standing water of
any kind has the potential to produce mosquitoes. Most of the
major locations around the District with standing water have already
been mapped, recorded and are regularly inspected and treated. We do
appreciate being notified of new or unknown mosquito sources.

A frequent source of backyard mosquitoes is ornamental ponds. To combat
this common source, we have a dedidcated team of technicians to help
homeowners enjoy these water features without steady swarms of
mosquitoes. In April, registered
homeowners receive a letter notifying them when
the season will begin and reminding them to prepare their pond(s),
us of any changes to their pond(s) or if their fish survived the
All pond owners will receive at least one of two options for
in their ornamental pond(s). Options include:
- live mosquito fish (Gambusia affinius) that aggressively eat mosquito larvae
- Altosid briquet(s) that prevent mosquito larvae from hatching into adult mosquitoes
Many ponds that have water features or such and will require both -
fish for the main portion of the pond, and briquets for water feature
portion to ensure complete control. Technicians are courteous to give a
call first, if requested, to
schedule an appointment where pets, locks, or other general access may
be a concern. Otherwise, fish or briquets are simply delivered and a
notice left on the homeowner's door noting the completed service.
Typically, a check back is completed later in the summer to make sure
the fish are thriving or briquets are working properly.
Bird baths and other water features should be emptied or cleaned regularly to minimize mosquitoes in your yard.

the heat of the summer, mosquitoes can easily
complete their life cycle in under a week making standing water in
horse troughs prime mosquito sources.
We ask horse owners
to be diligent in making sure horse troughs are emptied or cleaned at
least once a week. In attempt to help protect horses and minimize
mosquitoes we have a dedicated
technician who can give advice, information, and/or (at the
owners-request) a briquet that can provide mosquito control for up to
150 days. We are aware of the location of most horses in our District
and attempt to remind owners about maintenance with annual doorhangers.
Like humans, horses are also susceptible to West Nile virus
but have an effective vaccine available. We highly recommend all horse
owners have their horses vaccinated for West Nile virus by a licensed veterinarian.

addition to mosquitoes, the District also controls black flies which
can be a nuisance for farmers and ranchers. They bite
livestock, especially around eyes, ears and reproductive organs. Like mosquitoes, black fly
life begins in water. They however prefer flowing water (whereas mosquitoes need stagnant water)
and can be found in canals, ditches, and the Jordan River. They fly
erratically and in swarms and are not your typical picnic fly.

The western tree-hole mosquito (Aedes (Jarnellius) sierrensis) is
a common mosquito on the eastern bench areas of the Salt Lake Valley.
As its name suggests, this mosquito lays its eggs in wet tree holes
typically found in older gnarled trees. Tree-hole mosquitoes are
aggressive day biters and can be a real nuisance. They also are the primary vectors of dog heartworm.

While the main focus of the District is larval control, we do have a program designed to reduce adult mosquito
populations if they become too much of a nuisance or if there is a risk to public health. Prior to fogging (or
adulticiding) in any particular area, we place a trap to verify the
presence of a large adult mosquito population. CO2
and Gravid traps
are placed around the District May-September and results collected
weekly in order to monitor mosquito activity throughout the District. CO2 traps work by emitting carbon dioxide attracting mosquitoes.
Gravid traps specifically target egg-laying female
mosquitoes with the use of "stinky" water. Samples from both types of
traps are sent to the State Health Department weekly for West Nile
virus testing as
an indicator of the disease in the area.
addition to traps
placed weekly, we have a number of traps that can be placed upon
request. If it is determined that fogging is needed, we will proceed
with fogging an area. We do two different types of fogging - by truck
or by handheld sprayers for smaller specific areas like yards. As
required by the label, We

Are you a teacher or
know one that may be interested in having us visit a classroom? We also
do classroom presentations for 4th and 5th grade students throughout the
school year. See our Education page for more details!
You can also regularly find us at a booth at health fairs and city
event celebrations. Watch our Facebook page for upcoming dates and
We also have an entire crew dedicated to inspecting every catch basin
(also commonly known as storm drains) throughout the District multiple
throughout the summer and treating as necessary. Urban mosquitoes that
can carry West Nile virus
thrive in catch basins.
Keep an eye out for these bike crews in bright
orange protecting your neighborhood. By keeping catch basins and gutters near your
home free of debris you can minimize standing water on your street.
