Controlling for Aedes Mosquitoes
Challenges of Invasive Aedes
• Have rapidly spread throughout
California.
• Found in every city in LA County
• Prefer smaller water sources, making

• They lay their eggs in water sources
in people's front yards, backyards,

• Areas where mosquito control agencies
can't easily inspect

What is SIT?
• Environmentally-friendly insect pest control method
• A non-chemical control method
• The basic steps of SIT are:
• Sterilization of a target pest (mosquitoes),
• Release of sterile males in a specific area over time • Sterile males will mate with wild females
• The SIT technique results in no offspring and a
declining pest population, reducing the presence
the specific breed of virus-spreading mosquitoes
11 Different SIT Techniques
Wolbachia: Wolbachia is a common type of
bacteria found in insects. Approximately 6 in 10 of
all types of insects, including butterflies, bees, and
beetles, around the world, have Wolbachia. 00000
Wolbachia is injected into
Aedes aegypti eggs

Different SIT Techniques
Irradiation: Irradiation, such as with gamma rays and X-rays, is used to sterilize mass-reared insects so that, while they remain sexually competitive, they cannot produce offspring.

What you need to know
• Male mosquitoes do not bite and can not transmit diseases • SIT will not eliminate the use of other chemicals to control for mosquitoes.
• SIT only targets one specific type of mosquito
• Aedes aegypti
• SIT releases will have to be ongoing every
mosquito season
• The District is evaluating the use of SIT and has
not decided on a technique or when it would be
used
15 Can Mosquitoes Transmit
COVID-19?
"Mosquitoes cannot transmit
COVID-19"
-Dr. Sylvie Briand
There is no information or Director of Global Infectious Hazard Preparedness, evidence to suggest that World Health Organization
COVID-19 could be
transmitted by mosquitoes.

17 GET RID OF STANDING WATER AROUND YOUR HOME
• Once a week -empty and scrub, turn over, cover or throw out any items that hold water.
• Tip and Toss any standing water (indoors and outdoors) •REMOVE, SCRUB, FLIP OVER,
or COVER any dirty containers
that can hold water
• Drill a hole at the bottom of
open containers
