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 or BGS trap)
is a mosquito trap used by mosquito professionals
The BG-Sentinel mosquito trap:
- mimics convection currents created by a human
- 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
Used in combination with the BG-Lure, a dispenser
which releases a combination of non-toxic substances
that are also found on human skin (ammonia, lactic acid,
and caproic acid), the BG-Sentinel is especially
attractive for the yellow fever (or dengue) mosquito, Aedes (Stegomyia) aegypti,
the Asian tiger mosquito, Aedes
(Stegomyia) albopictus, the
southern house mosquito, Culex
quinquefasciatus, and selected
With the addition of carbon dioxide, the
BG-Sentinel is an exellent surveillance tool for
mosquitoes in general.
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
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.
