The BG-Counter 2 is an electronic device that counts mos-
quitoesastheyythroughandwirelesslytransmitsthedata
toacloudserver.Dierentiationofmosquitoesfromsmaller
or larger insects, and from other objects such as dust or rain
particles, is based on size and wing beat. Mosquitoes, small
Diptera such as chironomid midges and fungus gnats, and
otherinsectswithasimilarsizecannotbereliablydieren-
tiated.Therefore,toimproveclassicationaccuracy,theBG-
Counter 2 utilizes carbon dioxide (CO2) to attract only blood
sucking insects. By using CO2as an attractant the accuracy
of correctly counted mosquitoes is in the range of 80-90 %.
Accuracy may vary from location to location and should be
veriedfromtimetotime(seeaccuracyofcounts).
We recommend to use the BG-Counter 2 in combination with
BG-Counter 2 Description and Set-Up
a BG-Trap Station and a BG-Pro trap. The trap removes the
insects after they are counted, avoiding multiple counts of
the same insect. To ensure accurate counts, collected mos-
quitoes must not escape from the trap.
Equipped with basic sensors, the BG-Counter 2 also samples
local environmental data such as temperature, humidity
and light. The system is supported by the BG-Counter App,
a web application for storage of mosquito counts as well as
geospatial and environmental data. Via the BG-Counter App
you can remotely switch the trap and the BG-Counter 2 on
ando.Italsoallowsyoutosetupvaryingtimeschedulesto
run the trap and control the application times of CO2. The app
includes an analyzer tool that allows you to vizualize graphs,
maps and tables of your monitoring data. You can analyze
daily, weekly, or monthly trends of single or multiple traps.
The BG-Counter 2 is the next generation version of the BG-
Counter.Itoersthefollowingimprovementsoverthepre-
vious model:
1. Internal antenna
2. Notaectedbyeventualsunsetof3Gnetwork
3. Improved protection against corrosion and environmen-
talinuences
BG-Counter 2
4. Better insect classication accuracy through improved
algorithms
5. 4G Cellular Communication Module, works on the LTE
cellular network
6. The BG-Counter 2 comes with a BG-Pro trap (counter ver-
sion with 12 V fan).

Set-Up with the BG-Trap Station (recommended)
1. Assemble BG-Pro parts
Follow the assembly instructions for the BG-Pro. See ma-
nual at » www.biogents.com.
In case you have already a BG-Pro:
• Do not add a UV light.
• Do not add a funnel.
• Always run the BG-Counter 2 with the 12V BG-Counter
fan included in the contents of the BG-Counter 2.
• If you do not use a BG-Trap Station, attach the tripod to
place the trap on the ground.
2. Add a BG-Lure
We recomend to add a BG-Lure into the body of the BG-
Pro [F1]. When using the BG-Lure in addition to CO2, it
acts as an synergist and can multiply your mosquito catch
rates and increase the accuracy of the BG-Counter 2.
Central upper bracket
WARNING
The BG-Counter 2 runs on 12 V. Never connect the BG-Counter 2 to a voltage
above 14.4 V.
When using the BG-Counter 2, always conrm that the rated voltage on the
fan label is 12 V (Biogents SKU 10042). Do not connect a 6 V fan!
3. Assemble the BG-Trap Station
Assemble the stand by xing the beams on the lower
plate with the enclosed socket screws. Place the upper
plateontheotherendsofthebeamsandalsoxthem

the central upper bracket of the BG-Pro [F3]. Continue
to insert the screw through one of the holes of the trap
holderoftheBG-Trapstation[F4]andxitwithanut.
Repeat this process with another screw and the second
hole.TheBG-Proshouldnowbermlyattachedtothe
BG-Trap station [F5].
5. For routine operation of the BG-Counter 2, we recom-
mend to not install a catch bag.
A catch bag and funnel net can be installed when the
trap and BG-Counter 2 are run only overnight or for a
few hours, with the aim to manually inspect the catch
bag:
Attach a funnel net and a catch bag to the bottom part
of the BG-Counter 2 [F6]. The funnel net is important to
avoid double counts of insects crawling out.
For more information about this topic see chapter “De-
termination of Counting Accuracy”.
6. Place the BG-Counter 2 into the opening on top of the
trap[F7]andturnitclockwiseuntilittstight.
7. Connect the fan to the BG-Counter 2
Connect the red fan adapter cable with the fan cable of
the trap. Please pay attention to always connect with
the arrow in line with the black marking line [F8].

Option 1: Power cord with transformer
This is recommended if AC power is available at the counter location.
• Use only the provided AC adapter, and conrmlocaloutletstylebefore
ordering:
• US: Nema 1-15
• Europe: CEE 7
Only connect to outdoor AC outlets with a weather-proof cover comply-
ing with local electrical codes.
3 options to connect the
BG-Counter 2 to power via
the 12 V power connection
Option 2: 12 V battery (provided by user)
This is recommended if the counter is operated in a location for a few days,
before being serviced or moved. The minimum number of hours of operation
possible with a full battery can be calculated as follows:
Operation hours = Battery capacity (Ah) x 2.
For example, with a battery capacity of 60 Ah (Ampere hours), the counter and
fan can be operated for at least 60 x 2 = 120 hours = 5 full days.
Use only “deep cycle” lead-acid batteries. Normal car batteries are not desig-
ned for continuous charge/discharge cycling, and thus would have signicantly
reduced lifetime.
• Connect battery using battery cable
Connecting the BG-Counter 2 to Power: 3 Options

10
Option 3: Solar panel with solar battery
This is recommended when the system needs to be operated autonomously for extended periods of time.
While the trap/Counter are usually placed in a shady location, the solar panel should be placed in a sunny spot nearby; the
charge controller and battery should be placed near the counter.

WARNING
When setting up solar system connections, it is mandatory to follow these instructions!
1. Never connect the BG-Counter 2 to the charge controller unless a fully charged 12 V battery is connec-
ted rst.
2. Never disconnect the battery without rst disconnecting the BG-Counter 2.
3. Do not alter the wires provided with the solar sytem

1. Automatic start-up
TheBG-Counter2hasnoon/oswitchorotherbuttons.It
automatically starts when connected to 12 V power.
2. Battery check
After the counter is connected to power, there will be from 1
to 4 beeps, depending on battery voltage.
• 4beepsmeanthebatteryissucientlycharged
• If you hear 1-3 beeps, it indicates that the battery is low
and needs charging. The counting function, fan, and CO2
willbeountilthevoltageincreasesto>11.8V
• If there is no beep at all, see chapter Troubleshooting /
Trap does not start up
3. Cellular connection check
Following the battery check, the device proceeds to check
the strength of the cellular connection. This usually takes
less than 30 seconds, but may take several minutes, for ex-
ample, if the counter has been moved to a new location with
adierentcellularprovider.
At the end of the check, the counter indicates signal strength
as follows:
• 1-5 long beeps: corresponding to 1-5 bars of signal
• 2 short beeps: no signal, no cellular connection possible
If no cellular connection is available, the counter can still be
operated. Data will be stored internally, and transmitted the
next time a connection is available.
4. Fan and CO2 ow check
After powering up, the fan and CO2valve are switched on
until the next round 15-minute interval (for example, if po-
wered up at 16:03 until 16:15). This provides time for the
operatortoconrmthattheBG-Pro12Vfanisworking,and
the CO2owison.
Conrmfanoperationvisuallybylookingintothetrapfun-
nel, or by holding a piece of tissue paper above the funnel.
By default, the CO2owisadjustedto50g/h.TheCO2dosing
valveislocatedinsidethecounterhousing.Itbrieyturnson
andoevery4seconds.
Check for the presence of CO2 ow as follows:
• Make sure that the CO2tank valve open
• You should listen a click sound from the valve
• You should listen a hissing sound from the CO2release port
5. Counter check
You can verify the functioning of the counter by throwing
a small object (for example a small piece of paper) into the
trap funnel. A short beep indicates that the counter has re-
gistered the object.

Determination of Counting Accuracy
Catch bag
For routine operation, it is not recommended to use a catch
bagasitmightlluptooquicklyandresultincountinger-
rors. For routine operation with the BG-Counter 2, the BG-Pro
is used without a catch bag. Mosquitoes are sucked through
the ventilator and end up dead at the bottom of the trap.
A catch bag can be installed when the BG-Counter 2 runs
only for a few hours in order to check if the number of coun-
ted mosquitoes by the BG-Counter 2 corresponds with the
actual number of collected mosquitoes. In this way the accu-
racy of the BG-Counter 2 can be determined.
Protect the trap from predators
When comparing manual catch bag counts to electronic
counts, note that mosquitoes can “disappear” from the catch
bag:
Mosquitoes and other insects may be “stolen” by ants, spi-
ders, or geckos. Therefore, make sure for all calibration ex-
periments that ants or other predators have no access to the
catch bag. You can protect the trap by placing a water sur-
face around it, or by adding glue or PTFE to all trap parts that
might be accessible for predators.
Check CO2 settings
The accuracy of the BG-Counter 2 strongly depends on the
presence of CO2. Make sure that CO2is turned on during the
whole time range that you select for determination of the
Counter‘saccuracy.Werecommendaow-rateof50g/h.
Compare
If you make sure that mosquitoes do not leave the catch bag
after they have been sucked in, the accuracy of the BG-Coun-
ter 2 for correctly counted mosquitoes is expected to range
between 80% and 90%.
Make sure to compare the catch bag results with the electro-
nic results reported for the same time interval!
This means, that you should install and take out the catch
bag as close as possible to a round 15 min intervall. Make
a note of the exact time range in which your catch bag was
attached to the BG-Counter 2 (e.g. the time range of your
manual counts. After downloading the raw data of the BG-
Counter 2 (p. 30), make sure to only consider the number of
mosquitoes that were counted in the same time range!
The BG-Counter 2 is reset every time the power is disconnected and re-connected, and the start-up sequence commences as
described above.
Daily
Check the dashboard of the BG-Counter 2 web app for
warnings or error messages. If a fan or voltage problem is
indicated, or there are no new transmissions, take corrective
actions immediately.
Every 2 weeks
Inspect and clean the counter and trap, as necessary:
• Remove everything that deters mosquitoes from ente-
ring the trap such as spider webs, leaves, and dirt.
• Empty the catch bag.
• Wipe the counter housing and the inside of the funnel
to remove dust or other contaminants.
Depending on local conditions, more frequent service
may be required.
CO2
• ReplaceorllCO2tank as necessary.
• Access the web app and update the CO2trap settings at
each replacement (blue “Fill CO2” button).
BG-Lure
• Replace the BG-Lure every 5 months.

The BG-Counter App is a multifunctional tool that allows you
to manage your BG-Counter/s. You can for example remotely
switchtrapsintheeldonandoandsetupvaryingtime
schedules for the traps and application times of CO2. There
aredashboardnoticationicons,whenoneofyourtrapshas
an issue, such as for example connection problems, ventila-
tor fail, or low CO2level. Furthermore, you have access to all
collected mosquito count data, and local environmental data
such as temperature, humidity, or ambient light. The web
app includes an analyzer tool that you can use for explora-
tory analysis of the catch count data of single or multiple
traps. You can for example compare the mean catch rates of
dierent neighborhoods, or simply visualize the mosquito
catchesofasingletrapondierenttimerangesandfordif-

Trap
On the website and in these instructions, the word “trap”
refers to a complete system including a trap (BG-Pro or BG-
Sentinel) and a BG-Counter 2. Each trap is uniquely identi-
edbytheIMEIoftheBG-Counter2.
Location
Each trap is assigned to a location – the place where the trap
is installed to count and collect mosquitoes.
IMEI
IMEI stands for International Mobile Equipment Identity.
ThinkofitasyourBG-Counter‘sngerprint—it‘sa15-digit
number unique to each device.
Info Icons
Youndinfoiconsatseveralplacesofthewebapp.Hover
over the icon with the mouse and a window with more infor-
mation will pop up.
Basic Concepts
Geo-tags
Each Location automatically gets the geo-tags “Country”,
“State”, and “City” assigned.
Therearetwoadditionalgeo-tagsthatyoucandeneyour-
self: “Custom Group 1” and “Custom Group 2”. If you have
multiple traps in the same city, you could, for example, use
“Custom Group 1” to specify the neighborhood, and “Custom
Group 2” to characterize the biotope, such as for example:
suburban, urban, forest, lake, swamp, park, or similar. It is not
mandatory to assign your locations to custom groups. The
geo-tags allow you to make group-based analyses of your
catch count data.
Tables
Sorting function
All tables include a sorting function for every column: click
on the arrow that appears, when you hover with the mouse
over the name of each column. When you click on the arrow
forthersttime,itwillshowupwardsandsortthetableinan
ascending order. When you click on the same arrow again, it
will point downwards and sort the table in a descending or-
der. This function is helpful if you have many traps and want
to easily identify for example those traps, that have error no-
tications,ortrapsthathadanunusuallyhighorlowcatch
rate in the previous night.
Search function
All columns that have a magnifying glass icon include a
search function: click on the magnifying glass and type in
some info that makes it easier for you to nd the desired
trap/s. For example, in the dashboard, you can specify in the
“Catch Count” column, that you only want to see the traps
that collected between 150 and 200 mosquitoes since last
noon.
• go to “Dashboard”, then click on a location name, then
on the “View/Edit” button to set the trap name, schedu-
le, mosquito catch threshold, custom groups, etc.
• go to “Traps” to check the subscription status of your
devices, to assign a manually created location to an IMEI,
to register traps, to change the geolocation mode of your
traps.
BG-Counter App: Quick Start
• go to “Users”, then click on the “New User” button to

Trap counts, environmental data, and other parameters like CO2schedule are stored by location. Traps can be assigned to lo-
cations manually, or automatically using transmitted GPS coordinates.
Data storage based on Location
When Geolocation is set to “Auto” (= default setting), the lo-
cation will be automatically determined via geofencing:
• When a trap is within the geofence radius (100 m) of an
existing location, it will automatically assign itself to that
location
• Otherwise, a new location will be created automatically
with a default name that includes the IMEI.
When Geolocation is set to “Fixed”, the trap data will be assi-
gned to a selected location independent of transmitted GPS
coordinates.
You can edit a location at any time in the Trap Info table of
the “Settings: Single Locations” page (see p. 20 for details).
Examples: What does data storage based on location mean for you
These examples are also explained in the video linked on page 39.
Example 1: You have several traps, but you use them only
during a part of the year.
At the start of the new season, when you put the traps back
to the eld at already existing locations, set geolocation
to auto and the traps will automatically assign themselves
to their locations. You don’t need to make sure that a BG-
Counter 2 unit with a certain IMEI is placed again at the same
location, to have a continuation of historical data.
Example 2: You have more locations than traps and rotate
the traps between them.
The collected data will be automatically stored for the lo-
cation the trap is currently at. Instead of having all the data
stored for one IMEI, it is stored for as many locations as the
trap was used at.
Example 3: A BG-Counter 2 is defective and replaced. The
new BG-Counter 2 is placed at the same location.
The data of the two BG-Counter 2 units (e.g., 2 IMEIs) will be
stored for the same location and you will have continuation
of your historical data for that location.
Example 4: You need to place two traps within 100 m.
This is also possible, but we recommend creating the loca-
tions manually in this case: Click on the “New Location” but-
ton above the Location Table of the dashboard. Use Satellite
View to determine the exact position on the map and use the
right mouse button to set the Location pin on the map. In the
“Trap Management” table (main menu: “Traps”), set Geoloca-
tion to Fixed and select the location for each trap from the
drop-down list of the “Current Location” column.

There are three line charts on the Location Summary page:
• “Catch Count” (2)
• “Trap Status Parameters - Temperature, Relative Humidity & Dew Point”
• “Trap Status Parameters - Battery Voltage & Ambient Light”
•
The “Catch Count” graph shows mosquito counts by default,
but you can click on “Large” and/or “Small” in the graph’s le-
gend (7), to add the count data of large and/or small objects.
By clicking on a category that is currently shown in the graph,
you can remove it. The same applies for the two other graphs.
All graphs show the data on a temporal resolution of 15 mi-
nutes. In the upper left menu, you can change the time range
(4) of the x-axes of all three graphs. By clicking on “other” (5),
you can specify a customized time range. When you select
one of the time range options “Today”, “This Week”, “This
