West Umatilla Vector Control
Districts Mosquito Control Policy:
The West Umatilla Vector Control District supports management
of vector populations when and where necessary by means of
an integrated program designed to benefit or to have minimal
effects on people, domestic animals, wildlife and the environment.
This integrated pest management policy recognizes that vector
populations cannot always be eliminated, but often must be
suppressed to tolerable levels for the well being of humans,
and wildlife. Selection of scientifically sound suppression
methods must be based upon consideration of what is ecologically
economically in the long-term interest of humankind.
The following principles are to be followed:
- Vector control measures should only be undertaken when
there is adequate justification based upon surveillance data.
- The combination of methods for vector control should be
chosen after careful consideration of the efficacy, health
ecological effects and cost versus benefits of the various
options; including public education, legal action, natural
control, elimination of the breeding sources, and pesticide
- Vector breeding sources, whether natural or created by
human activity, should be altered in such a manner as to
least undesirable impact on the environment.
- Pesticides and application methods should be used in the
most efficient and least hazardous manner in accordance
laws, regulations and available scientific data. The registered
label requirements for pesticide use should be followed.
When choices are available among effective pesticides, those
the least hazard to non-target organisms should be used.
Pesticides should be chosen and used in a manner that will
development of resistance in vector populations.
- Personnel involved in the Vector Control program should
be properly trained and supervised, certified in accordance
laws and regulations, and should keep current with improvements
in management techniques through continuing education and/or
All methods and materials used by the District
are based on these principals.
