5. The District’s Proactive Approach to Mosquito Control
Larval control
95%
Adult control
5%
• The bulk of our mosquito control focuses on the
immature life stages of the mosquito, which are
aquatic.
• Costs to kill mosquito larvae = $0.25/application
• Costs to kill adult mosquitoes = $100/application
• Every month the District inspects (on average)
15,000 potential breeding sites and treats them as
necessary
• To kill mosquito larvae, we primarily use a bacteria
that the mosquitoes ingest and then die. The
bacteria causes no deleterious effects to other
organisms or the environment.
Proactive
Reactive

6. Only Female Adult Mosquitoes Bite
Only the female mosquito
bites humans and other
animals.
They need an essential amino
acid found in blood to
produce their eggs.

11. How to Protect Yourself and Loved Ones From Mosquitoes

12. Mosquito fish Available for Free!
The stocking of mosquito fish for control is highly encouraged
by the District, and fish are provided to our residents free of charge.
Mosquito fish (Gambusia affinis) are small guppy like fish that can be stocked
in ornamental ponds, water troughs, bird baths, etc. to prevent mosquito breeding.
