Basic Knowledge: There are roughly 3500 different species
of mosquitoes worldwide and about 100 different species
in Europe. The perceived biting pressure is influenced by
the combination of mosquito species, the weather during
and before the mosquito season, particular events such as
floods, the climate history of the previous years and from
regional circumstances (distance to breeding areas and/or
resting areas of mosquitoes).
In addition, it is not only mosquitoes that cause the regular
‘biting pressure‘. Biting midges can also play an important
role in increasing the biting pressure in northern regions
and the countryside. Horse flies and biting flies can also be
frequently found in the countryside as well. Blackflies can
be extremely bothersome in areas with flowing waters.
Performance Range: The Biogents Mosquitaire CO2 attracts
mosquitoes within a 10 to 20 meter distance. It does not
attract mosquitoes outside of this area into your yard. The
area in which a Biogents trap reduces the mosquito popu-
lation, however, can be much larger than this range of up to
20 meters because mosquitoes will systematically explore
their surroundings. It is just a matter of time before an ex-
ploring mosquito from further away enters the range of the
trap and is caught.
Influencing Factors: The reduction of the biting pressure
by the Biogents Mosquitaire CO2 trap depends on various
factors.
1. The relation between the local population of mos-
quitoes and the new mosquitoes that fly in daily. This
depends on:
•
the species of mosquito in the area,
•
flooding events where millions of mosquitoes
hatch simultaneously and fly long distances,
•
the distance to the breeding areas of the
mosquitoes,
•
the productivity of the mosquitoes and
•
the distance to the resting areas of the
mosquitoes.
2. The number and size of the paths that mosquitoes
could use to access your property. If there are several
access paths, the BiogentsEisehans™ Protection Belt,
a system containing three Biogents traps, may be
required. (More information can be found under: www.

How you use the available resources and influencing
factors:
•
Certain mosquito species respond particularly well
to a high output of carbon dioxide.
•
Seasonal Approach:
- Begin operating the trap as early as possible on
the low level for CO2 consumption. (Please see
section ‘Positioning the trap: When and Where?’)
- Increase the amount of CO2 if the biting pressure
increases.
•
Analyse your property to determine the best
position for the trap and experiment with dif ferent
locations to determine the best. Note that
the quality of the trap location can change with
changes in wind direction.

Maintenance and Care:
A vacuum cleaner with a full bag or clogged filter
does not function properly anymore. This also
goes for the Biogents Mosquitaire CO2 trap.
Therefore, regularly check that:
I. the catch bag and funnel net are not clogged
with pollen, dirt or dust.
II. the catch bag is not too full. A halfway full catch
bag relates to tens of thousands of mosquitoes
and should be emptied.
III. the catch bag is not damaged or torn.
IV. there is still pressure in the CO2 gas cylinder.
V. the white gauze covering is still white! The white
and black contrast is an important part of the cat
ching technology of the Biogents trap and aids in
attracting mosquitoes to the intake funnel.
•
Replace the Biogents Basic dispener every six to
eight weeks.
