Pre-treatment Surveillance

Following inundation of breeding sites, Mosquito Operations Officers survey the sites to establish the presence of hatched larvae, the stage of larval development, numbers of larvae on a particular site, water depth and extent of inundation.  They also record the details of the site and any particulars that may be useful in the process of undertaking treatments.


There are more than 30 breeding sites across the City of Mandurah and surveying is conducted regularly. Many hours are spent undertaking this surveying, and this ground work is a vital component within mosquito management, providing essential information to the program to guide effective treatments.


The pre and post treatment surveillance aids the Mosquito Management team to plan the most effective treatment.
