While most people believe that mosquito control is nothing more than truck or backpack-based applications of pesticide, in reality, spraying to control adult mosquitoes is just one small aspect of a well-managed integrated mosquito management program. In fact, the foundation of every effective mosquito control program is Surveillance.

What is Mosquito Surveillance and why is it necessary?
Mosquito Surveillance is the routine monitoring of both larval and adult mosquito populations over the course of an entire mosquito season. Such mosquito surveillance is critical to a successful municipal or commercial mosquito control program for several reasons:

1. Monitoring changes in mosquito populations 
2. Identifying which mosquito species are present
3. Detecting mosquito-borne diseases
4. Determining what control measures need to be conducted

Monitoring changes in mosquito populations is important because it allows mosquito control experts to track exactly where the larval and adult mosquito populations are rising or falling. These data, when compared to previous weeks or previous years, provides the knowledge we need in order to identify and predict perennial, sporadic, or new problem areas, as well as to predict possible increases in the risk of mosquito-borne diseases.

Identifying which mosquito species are present provides mosquito biologists with information they can use to locate mosquito breeding habitats, determine the severity of a nuisance mosquito outbreak, and provide knowledge about what mosquito-borne diseases may be present in a given area. Different mosquito species often display different behaviors and may require different control measures due to variations in their life histories. Many mosquitoes have different breeding habitats, activity (biting) periods, host preferences and maybe most importantly, which diseases they can transmit.

Highly trained mosquito biologists work in a lab to identify and count all of the mosquitoes that are collected and either send the appropriate species to State or University labs for testing, or test them in-house for specific diseases, such as West Nile virus. In most cases, the diseases that mosquitoes can transmit to humans and animals can be detected in the mosquitoes themselves, weeks before they can be passed on, which gives experts the opportunity to take all of the appropriate control actions in order to reduce the risk of human disease transmission.

How is Mosquito Surveillance Done?
Mosquito surveillance is typically conducted by first dividing a program area such as a city, county or industrial facility into control zones. Within each zone an experienced field technician collects mosquito larvae from standing water sources using standardized dipping techniques, while surveillance technicians set adult mosquito traps. Adult mosquito traps are left out over-night, collected the following day, and taken to a lab for counting, identification and disease testing. There are several types of adult mosquito traps used in effective mosquito surveillance programs, each with its own advantages, depending upon what specific information is desired. Some of the traps commonly used include:

• CDC Miniature Light Traps
• Gravid Traps
• New Jersey Light Traps
• BG-Sentinal Traps
• Ecovec MosquiTRAPs
• Landing Rate Counts


It is highly recommended that any municipality or large industrial operation conduct a comprehensive mosquito surveillance program as the first step towards protecting the public health of its citizens or employees. The experienced team at Vector Disease Control International (VDCI) collects and analyzes several hundred thousand mosquitoes every year for cities, counties, districts and companies across the United States.

Since 1992, Vector Disease Control International (VDCI) has taken pride in providing municipalities, mosquito abatement districts, industrial sites, planned communities, homeowners associations, and golf courses with the tools they need to run effective mosquito control programs. We are determined to protect the public health of the communities in which we operate. Our mosquito control professionals have over 100 years of combined experience in the field of public health, specifically vector disease control. We strive to provide the most effective and scientifically sound mosquito surveillance and control programs possible based on an Integrated Mosquito Management approach recommended by the American Mosquito Control Association (AMCA) and Centers for Disease Control and Prevention (CDC). VDCI is the only company in the country that can manage all aspects of an integrated mosquito management program, from surveillance to disease testing to aerial application in emergency situations.
