The route inspections take place almost continuously from March through October. During the months of November through February sites are still inspected with relation to water management activities, fish population monitoring as well as access brushing and route modification (incorporation of new sites identified earlier in the year and revision of directions and site descriptions into the routes as necessary).
If a complaint is received and an area is inspected for the presence of adult mosquitoes, the staff member responsible for the district in which the complaint falls, will look for adult mosquitoes during the site visit and/or place a portable light trap at the site for a 12-24 hour collection.
When site inspections take place, collections of larval and or adult mosquitoes are made and brought back to the office (lab) for identification to document the species and numbers present at any given area. These inspections and surveillance techniques as well as the identification process generates and justifies the short term control measures, aids in the assessment of the disease and nuisance potential of the mosquitoes in any given area and helps to guide the long term control strategy as well.
