Dragon Mosquito Control, Inc specializes in the development and implementation of municipal mosquito control programs. All programs are designed in accordance with Integrated Mosquito Management (IMM) best management practices and the NH Arboviral Illness Surveillance, Prevention and Response Plan. click for more information

Once a municipality has determined they have a need for mosquito control, the work can begin... in the winter. A Special Permit issued by the State of NH must be secured prior to conducting a control program. Dragon submits Special Permit applications in the winter to guarantee issuance by early spring. Applications describe in detail the mosquito management plan for the town and are accompanied by supporting surveillance data and GIS maps. Yearly, these applications are scrutinized by various NH State Agencies and a permit is issued. All control measures must be conducted in accordance with the Special Permit.
Mosquito control begins with a comprehensive look at a town’s geographical area from the sky. We identify potential mosquito habitats using satellite photos, paper maps, tips from residents and other sources. Over the past several years, Dragon has integrated GIS mapping into our control programs. This allows for geographic information to be managed, manipulated, easily displayed, and quickly understood allowing for a more efficient and effective control program. This is just one of the many ways Dragon has used technology to improve control efforts.
The next step is visiting sites on foot and sampling mosquito larvae. A thorough assessment is conducted for all potential mosquito habitats, during which wetlands are mapped and site data is collected. Contrary to popular belief, not all wetlands support mosquito larvae. Larval surveillance is conducted throughout the mosquito season.
Larviciding is only conducted after larval surveillance data has confirmed a need and action thresholds have been exceeded. This method of prescriptive larviciding is highly effective, killing immature mosquitoes before they get a chance to mature into winged adults and pose a biting risk. Following larvicide treatments, mortality assessments are performed to ensure that our approach is producing the desired results.
As the mosquito season progresses, adult mosquito surveillance begins. Surveillance is an early detection system to confirm the presence of diseases such as Eastern Equine Encephalitis (EEE) and West Nile Virus (WNV) as well as an indicator of mosquito population trends.
We deploy various types of mosquito traps depending on the targeted species. Captured mosquitoes are then frozen, identified, pooled by date & location, packed in dry ice and sent to the State Laboratory for testing. (A mosquito pool is a grouping of trapped mosquitoes by collection date, location, and species - not a specific pool of water.)
Positive EEE/WNV test results will trigger a reassessment of risk levels and immediate discussions with town officials. At this point, spraying adult mosquitoes may begin in accordance with the scope and scale outlined in town contracts. Some towns request emergency spraying only in limited areas (such as the edges of school athletic fields) while others select broad-scale treatment. All control measures are guided by adult mosquito surveillance data and disease test results.
Dragon utilizes state-of-the-art Ultra Low Volume (ULV) truck sprayers for large-scale road spraying and backpack sprayers for treatment in areas that are inaccessible to vehicles or areas that require targeted spot treatment.
