2. Primary – monitor and suppress public health vectors and their disease  Mosquitoes  Rodents  Dust Mites Secondary – monitor and suppress pests of medical importance  Bed Bugs  Spiders of medical importance  Cockroaches Integrated pest management methods MISSION

3. Many different agencies providing vector services 1)Vector district 2)Health department or health district 3)Others Multiple agencies responding in one community Statewide or province-wide service coverage does not exist Infrastructure WHO WE ARE

4. FEDERAL LAND MOSQUITO CONTROL Managed for single use; not multi-managed Managed where public health perspective is commonly absent Processes and procedures for appeals either do not exist USFW refuge policy does not allow for regional variance due to local mosquito biology

5. Inconsistent requirements for NPDES in Region 10 at state level OR and ID – not required WA – required for larvicides only; not adulticides  Limits IPM capacity  Additional risk assessment independent of EPA risk process  Does not incorporate local mosquito bionomics – non-feeding larva THE CLEANWATER ACT

6. Storm water structures – 130/mile 2

7. LABELS Label language; unclear, dual use and or inconsistent EPA PR 2005-1 notice –reviewed for 7 key improvements  Define who is “trained personnel”  Multiple usage; separate out mosquito control  Clarify environmental precaution language  Broaden consulation requirement  Clarify droplet size/application  Clarify pollinator avoidance  Clarify timing of application language Completed through registration process - ongoing

8. PUBLIC PERCEPTION AND EXPECTATION Technical language is cumbersome  “What is a pesticide?” Oregon 2004 survey – 44% television; 27% newspaper Honoring “no spray sites” - distinction between public areas and private areas Local mosquito biology is diverse  OR – 50 species; 19 disease vectors of WNV, WEE, SLE or malaria Changing human behavior
