Take all landing rate and bite counts from a standing position. Disturb the surrounding vegetation before starting the counts. Count only those mosquitoes that land within view. This permits county agencies to use one person to accomplish the jobs and is based primarily on economics. If work is conducted after sunset, the light source should have a red filter.
Red light is less repelling than white light.
Develop a standardized form to facilitate the recording and filing of information. Use real numbers on all forms. When collecting mosquitoes for identification, use some type of aspirator, either electric or lung powered. Be aware of the behavior of the species that is being monitored when interpreting data from landing rates and bite counts. Landing rates taken at mid day for a mosquito species that host-seeks at twilight may require adjustment to assess the magnitude of the problem.
