Mosquito Ecology
Invasive Aedes
▪ Daytime biting
▪ Container breeders; don’t
need much water
▪ VERY aggressive biters
▪ Breed indoors
▪ Extremely challenging to
control
▪ Eggs can survive
desiccation
▪ New disease threats
‘regular’ mosquitoes
▪ Mostly dawn/dusk biting
▪ Breed in marshes, creeks, stormwater system, containers, anywhere with water
▪ Not so aggressive
▪ Rarely breed indoors
▪ Under control with existing methods
▪ Can destroy eggs by dumping out
▪ Transmit disease

Keeping Invasive Aedes Out
▪ Don’t introduce
plants or containers
▪ Check for
eggs/larvae
▪ Eliminate breeding
habitat
▪ Report suspected
sightings

Red Flags for Invasive Aedes
Appearance
▪ Small size
▪ Dark-colored or black body
▪ White striped/banded legs
▪ ‘lyre’ shape (aegypti) or
stripe (albopictus) on
thorax
▪ Just looks ‘different’ than
usual mosquitoes
Behavior
▪ Daytime bites,
especially in
urban/suburban
areas
▪ Biting indoors
▪ Very aggressive biting
▪ ‘ankle-biting’
![Page 31: Invasive Aedes Mosquitoes in California - CAPCA...Surveillance and Control of Aedes aegypti and Aedes albopictus in the United States (CDC) Guidance for Surveillance of and Response](https://reader034.vdocument.in/reader034/viewer/2022042113/5e8f29607a261d18a855a5ea/html5/thumbnails/31.jpg)
If You Suspect Invasive Aedes:
▪ Catch or kill (without squashing!) for identification
▪ Note location, environment, date, and time of day
▪ Contact your local vector control district or ag department to report and provide sample

Why Can’t You Just Kill Them?

Physical Control
▪ Eliminate containers
▪ Clean up garbage and
other debris
▪ Focus on permanent
solutions – not just
dumping out water
▪ Resident participation
and cooperation
required
![Page 36: Invasive Aedes Mosquitoes in California - CAPCA...Surveillance and Control of Aedes aegypti and Aedes albopictus in the United States (CDC) Guidance for Surveillance of and Response](https://reader034.vdocument.in/reader034/viewer/2022042113/5e8f29607a261d18a855a5ea/html5/thumbnails/36.jpg)
Larviciding
▪ Bacterial larvicides
▪ Insect growth
regulators
▪ Oils (BVA-2, etc.)
▪ Large-scale
larvicide
applications may
be useful

Beyond the 5 D’s
▪ Dump & drain standing water
▪ Dress in long pants and sleeves
▪ Stay inside at dusk & dawn
▪ Use a repellent containing DEET
▪ Defend your home with window
screens

Plan Ahead
▪ Start the planning process NOW
▪ Consider resources and future needs
▪ Make cooperative agreements with
neighboring jurisdictions
▪ Meet with your local mosquito/vector
control agency
▪ Prepare the public for the arrival of
invasive Aedes
