Boulder County Plan
Boulder County’s plan to protect residents from
the effects of West Nile Virus (WNV) is two-fold.
First, it involves an
extensive education campaign to encourage you to:
- Protect
yourself by wearing protective clothing and using insect repellent.
- Protect
your property by eliminating standing water.
Second, is the implementation of significant surveillance factors that act as indicators for WNV activity:
- Increase
in numbers of WNV carrying species of mosquito (Culex
tarsalis spp) in traps around the county.
- Increase
in numbers of infected mosquitoes found in traps.
- Increase
in numbers of "positive" dead birds.
- Identification
of horse or human cases.
Only after each of these factors have been
evaluated is adulticiding considered. It is important to remember that
chemical application for control of adult mosquitoes makes up only 6% of
the program.
More than 94% of the program is biological and physical
control of mosquito larvae prior to adult emergence. This is part of our
Integrated Pest Management (IPM) Program for
Mosquito Control.
