The guiding force for all control operations in any IMM program is based upon the data obtained through regular surveillance.
Larval surveillance is performed through the inspection of water-holding areas and containers. Frequently, a dipper is used to sample the water for the presence of larvae. For the collection of adult mosquitoes, Tangipahoa Mosquito Abatement uses various traps and techniques to capture different species to be identified and counted. This aids in providing optimal control methods for the most affected areas.
