Portable CO2 Mosquito Attractant/Surveillance System

The Walter Reed Army Institute of Research has developed a portable system to attract mosquitoes and other biting insects for pest and disease surveillance of an area. Military and public health personnel are stationed around the world which increases the possibility of acquiring a vector borne disease. It is essential to accurately identify the types of mosquitoes and the disease threat in the field so appropriate prevention and control methods can be used.

The Technology: 

Currently available light traps are not effective in collecting vectors of top priority diseases like malaria, dengue, and leishmaniasis. Surveillance using proper traps and human-like lures to attract vectors would give more accurate data, such as species and numbers of each important vector in an area. Mosquito attractants, such as carbon dioxide generators, compressed CO2 or dry ice are expensive, can be difficult to obtain in some areas, require frequent re-supply, and are too heavy for use in the field. This Army technology is smaller, lighter weight, cheaper, more easily transported, and eliminates all other materials needed to produce carbon dioxide. The Army surveillance system can be used with a wide variety of arthropod traps and could be made into a kit for use in the field.


• Portable: Weighs less than a pound
• Low cost: Cheap alternative to current mosquito attractant methods
• Simple: Easy to use, and no issues with airplane transport
• Flexible: Will work with a wide variety of arthropod traps
• Multiple markets: Military medical care, mosquito control districts, public health organizations including the CDC and WHO, research institutions and pest management companies

The Opportunity: 

• A pending PCT patent application is available for license
