A result of more than 15 years of academic research into the host-finding of mosquitoes, the BG-Sentinel is the best trap for important disease transmitting mosquitoes.

The BG-Sentinel mosquito trap:

• mimics convection currents created by a human body
• employs attractive visual cues
• releases artificial skin emanations through a large surface area

The BG-Sentinel Trap is normally used in combination with a special dispenser for added sensitivity and specificity, the BG-Lure, which releases a combination of non-toxic substances that are also found on human skin: ammonia, lactic acid, and fatty acids.

Originally designed to attract the yellow fever (or dengue) mosquito Aedes aegypti, both laboratory and field tests continue to show that the trap is also attractive for a range of other mosquitoes.

The trap is essentially a collapsible pop-up container with a white gauze covering its opening. The diameter is 36 cm (14 inches), the height 40 cm (1.3 feet). In the middle of the gauze cover, air is sucked into the trap through a black catch pipe by an electrical fan, drawing approaching mosquitoes into a catch bag (yellow arrows).

The air then exits the trap through the white gauze, generating ascending currents (red arrows). These are similar to convection currents produced by a human host, both in its direction, its geometrical structure, and, due to the addition of the BG-Lure, also in its chemical composition.

Interesting for professional researchers and mosquito specialists: the BG-Sentinel is large enough to incorporate additional attractants such as fragrant substances, small living animals, worn clothing, animal hairs, light and heat sources, etc. This makes the trap a very versatile tool for both monitoring and research.
