BG-Sentinel

The BG-Sentinel™ is the best trap to monitor tiger mosquitoes (Aedes aegypti, Ae. albopictus and their relatives) and is used by professionals worldwide. The addition of CO2 also makes the BG-Sentinel™ an excellent trap for most other mosquito species. The catch bag is located above the fan, the specimens are not destroyed, can easily be identified and used for the determination of disease agents.

The full version comes complete with two catch bags, EU power supply (input 220 V), a battery mounting support, a 5-meter extension cable, and Sweetscent™ (increases catch rates for tiger mosquitoes.) No batteries are included - we recommend either car or motorcycle batteries with 11 Ah for every 24-hour catch period.



The BG-Sentinel mosquito trap

A result of more than 15 years of academic research into the host-finding of mosquitoes, the BG-Sentinel (a.k.a. the BG trap) is a mosquito trap used by mosquito professionals worldwide.

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
  • can be used without CO2 to specifically capture selected mosquito species
  • is an excellent general mosquito trap when used with CO2
The BG-Sentinel mosquito trap is essentially a collapsible, white fabric 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.
