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).
Description of the BG-Counter 2
We recommended to use the BG-Counter 2 in combination
with a BG-Trap Station (with parts of the BG-Pro with a spe-
cial 12 V fan) or a BG-Sentinel trap that remove the insects
after they are sucked through to avoid multiple counts of the
same insect. To ensure accurate counts, the trap must not
allow collected mosquitoes to escape.
Equipped with basic sensors, the BG-Counter 2 also samples
local environmental data such as temperature, humidity
and light. The system is supported by a web application for
storage of mosquito counts as well as geospatial and envi-
ronmental data. Via this web application you can remotely
switch the trap and the BG-Counter 2 on and o. It also al-
lows you to set up varying time schedules to run the trap and
control the application times of CO2.
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 Counter version
trap.

4EN
The BG-Counter 2 needs mobile reception to transmit data to
the web server. Therefore, place the BG-Counter 2 with the
trap only in areas with mobile reception. You can check the
local reception with your mobile phone.
BG-Counter 2 needs mobile reception
The BG-Counter 2 will automatically select the mobile provi-
der that is available at the chosen location.

How to Set-Up the BG-Counter 2 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.
Central upper bracket
Info
The BG-Counter 2 runs on 12 V.
When using the BG-Counter 2, always use the 12 V BG-Counter fan included in
the BG-Counter 2 contents (see page 5, 1.9).

2. Assemble the BG-Trap Station
Assemble the stand by placing the beams on both sides
in the clamps of the bottom ring and xing them with the
enclosed nuts [F4]. Place the lid clamps into the other
ends of the beams and also x them with nuts [F5].
3. Set up the BG-Pro in the stand:
Insert an enclosed screw through one of the holes on
the central upper bracket of the BG-Pro. Continue to
insert the screw through one of the holes of the trap
holder of the BG-Trap station [F6] and x it with a nut.
Repeat this process with another screw and the second
hole [F7]. The BG-Pro should now be rmly attached to
the BG-Trap station [8].

4. For routine operation of the counter, it is recommended
to not install a catch bag.
A catch bag and funnel net can be installed when the
trap and BG-Counter 2 are run overnight or for a few
hours, and the catch is to be preserved for inspection:
Attach funnel net and catch bag to the bottom part of
the BG-Counter 2 (if desired) [F9]. The funnel net is im-
portant to avoid double counts of insects crawling out.
For more information about this topic see chapter “De-
termination of Counting Accuracy”.
5. Place the BG-Counter 2 into the opening on top of the
trap [F10] and turn it clockwise until it ts tight.
6. Connecting the fan to the counter: 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 [F11].

The CO2bottle is not included, and must be provided by the
user.
There exist two dierent versions of the pressure regulator:
a) The preset regulator is adjusted to 2.0 bar and the outlet
pressure cannot be changed.
b) The adjustable pressure regulator must be set at 1.5 kg/
day (corresponding to 2.6 bar). Therefore, adjust pressure to
mark “C” on the dial.
The ttings of the regulators are either US CGA-320 or Euro-
pe W21.8x1/14 RH standards.
Connect CO2
F13F12
1. Install the CO2pressure regulator on tank and make sure
it is tight by using a wrench or pliers [F12].
2. Connect the free end of the CO2tubing to the regulator
[F13]: unscrew the nut on the outlet, thread the end of
the CO2tube through the nut, insert the end of the CO2
tube rmly onto the outlet and re-screw the nut back
onto the outlet.
3. Now open the valve on the top of the CO2bottle to start
the release of CO2.
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
Connecting the BG-Counter 2 to Power: 3 Options
3 options to connect the
BG-Counter 2 to power via
the 12 V power connection

10 EN
• Europe: CEE 7
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 “deep cycle” lead-acid, or lithium-ion batteries. Normal car batteries are not
designed for continuous charge/discharge cycling, and thus would have signi-
cantly reduced lifetime.
• Connect battery using battery cable
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 solar controller and battery should be placed near the counter.

Determination of Counting Accuracy
For routine operation, it is not recommended to use a catch
bag as the catch bag might be lled up too quickly. In this
way mosquitoes will be sucked through the ventilator and
end up dead at the bottom of the trap.
However, 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
counted mosquitoes by the BG-Counter 2 corresponds with
the actual number of collected mosquitoes. In this way the
accuracy of the BG-Counter 2 can be determined. When
comparing manual catch bag counts to electronic counts, it
should be noted that mosquitoes can “disappear” from the
catch bag:
Mosquitoes and other insects may be “stolen” by ants, spi-
ders, or geckos. For all calibration experiments make sure
that ants or other predators have no access to the catch bag.
You can protect the trap and catch bag by a water surface
around the trap, or by adding glue or PTFE to all trap parts
that might be accessible for predators.
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 between 80% and
90% correctly counted mosquitoes. If desired, experiments
can be performed from time to time to compare the catch
bag results with the electronic results reported for the same
time interval.
• The solar panel is deliverd with already connected PV-cable cables. Connect the
PV-cables to the charge controller [F14.1]
• Connect battery clamps to the battery and the other ends to the charge controller
[F14.2]. Pay attention to connect minus-pole to minus-pole (black) and plus-pole
to plus-pole (red).
• The charge controller is also deliverd with already connected cable [F14.3]. Con-
nect the charge controller cables to the trap [F14.4].

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 only 1-3 beeps are heard, this means the battery is low
and needs charging, and counting function, fan, and CO2
will be o until the voltage increases to >11.8V
• 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
Operating the BG-Counter 2
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 pow-
ered up at 16:03 until 16:15). This provides time for the ope-
rator to conrm that the BG-Pro 12 V fan is, indeed, 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:
• CO2tank valve open
• audible click from the valve
• hiss from the CO2release port
5. Counter check
If desired, the function of the counter can be veried at this
time by throwing a small object (for example, a small piece of
paper) into the trap funnel. A short beep is heard, indicating
the counter has registered the object.
The rst connection to the Cloud (http://www.bg-counter.
com) takes place at the rst round 15 minutes after the coun-
ter is started (for example, 16:15).
When connecting to the cloud, results are uploaded, and the
schedule dened on the web site is downloaded and acti-
vated.
First Cloud Connection
Reset
The BG-Counter 2 is reset every time the power is disconnected and re-connected, and the start-up sequence commences as
described above.
Depending on the schedule, fan, CO2and/or counting
function may be turned o at this time.
If this is a new counter, the rst connection also auto-registers
the counter on the website.
Maintenance
Check the BG-Counter 2 and trap bi-weekly or once a month for functionality, remove everything that deters mosquitoes
from entering the trap such as spider webs, leaves and any dirt.

After selecting and clicking a trap, the trap page is shown. Here you nd all of the data belonging to the trap inclusive capture
data. Further you can set a timer for CO2release and fan and counter operation.
Trap Location
On top of the trap page the trap location is shown in a Google map. When rolling over the marker with the mouse, the name
of the trap is shown:
Types of coordinates
Location is normally determined using the build-in GPS. If
no GPS x is available, an estimated location is provided
using triangulation of the cellular signal. With “zoom in“ the
dierent circles will get visible:
GPS Location: Green circle, accuracy about 50 m (11)
Cellular Location: Red circle, accuracy about 10 km (10)
Setting “Exact” coordinates
Since mosquito counts are strongly correlated with exact
trap location (down to the nearest bush perhaps), it is possi-
ble to use Google Maps to set the exact location of the trap.
Click on the pencil icon next to “Trap Location” (11). Now, an
arrow is shown below the trap label which points to the exact
location. Click and drag the label to the desired location,
zooming in and switching between map and satellite view
as required. The location is saved when clicking on an item
outside the map.
Default location
If a newly registered trap has not yet transmitted a location
signal, the location displayed will be either the last known
location (which can be some distance away from the present
location) or the location of the prime meridian in Greenwich,
UK.
The location displayed is the last known location. For histo-
ric data, the best estimate of the location on the day selected
in the main chart is shown.

Trap Information
The trap information in the right box provides general data
to your trap like name, IMEI (International Mobile Equipment
Identity), last connection, and level of CO2cylinder.
For changing these data, click on the pencil icon next to the
“Trap Information” (12).
Name
To change, click on the text eld, and enter the new name
(13).
CO2cylinder
On the main trap page, an estimate is provided for the cur-
rent ll status of the CO2cylinder, and the time left until em-
pty. For the estimate to be correct, it is necessary to have a
xed schedule, and to indicate when the cylinder was last
lled.
Cylinder size (kg)
Click on “Please select” or the current size, and pick a size
from the drop-down list (14).
Fill
Click on the “Fill” button, and then select the date and time
at which the cylinder was last lled (15).
Flow rate
The ow rate is automatically set to 50 g/h. This is the op-
timum number for operation of the BG-Counter 2 to attract
mosquitoes while at the same time repelling other insects.
This eld cannot be edited.
Data connection
Determines how often the counter will try to connect to the
website, and transmit counts and other data (16). The default
is every 15 minutes. Other choices are every 1, 2, 4, and
8 hours (Independent of this setting, count data are always
stored with 15-minute resolution).
The 15-minute setting is useful for diagnostics when the
counter is rst set up. However, during each transmission,
counting stops for 15-120 seconds, depending on the cellu-
lar signal strength. This can result in a small undercounting
error. In order to minimize this error, a data connection peri-
od of 1 hour or longer is recommended for routine operation.
A new setting is transmitted at the next data connection, i.e.
if previously the interval was set to 4 hours, and now an in-
terval of 1 hour is desired, it may take up to 4 hours until the
new setting is transmitted.

Trap Schedule
20
The trap schedule is used to control the operation of the trap: Here you can set a timer for the CO2release and the operation
of the fan and the counter. For each 15-minute interval during a day, the on/o status can be selected for the following:
• CO2: green = on, white = o.
• Fan: blue = on, white = o.
• Counter: orange = on, white =o.
To change the schedule, click on the pencil icon next to “Trap
Schedule” (18).
These elds can be set independently, although normally
they are all on at the same time. However, if for example a
catch bag is installed, and the catch is to be retained for coll-
ection, leave the fan on continuously.
Normally, the schedule is set to repeat daily; however, it can
also be set dierently for every day of the week (19).
18
Clicking and dragging changes the status (click on the circle
with a question mark for a short demo (20)).
Click on “Save” to save the new schedule, or click on your
browser’s back button to return to the previous page without
changing the schedule.
A new schedule is downloaded to the trap, and becomes
eective at the time of the next data connection (see Data
Connection in the “Trap Information“).

Chart settings
Here you can view the captures of your trap.
Exporting data into Excel
Clicking on the Export button brings up the “Export Data”
window (28). Here you can select a date range for export,
whether data are exported from 0-24 hours or 12-12 hours,
and the format of the export le (EXCEL or CSV, comma-se-
parated values.)
Daily charts
Scroll down below today’s chart, and click on “Load Daily
Charts” to display small charts for the last 30 days (29). This
is a convenient way to spot trends.
Note: Since a large amount of data is searched, it may take
up to 20 seconds or more to update the display.
Insect counts
Clicking on the “Counts” button (30) opens the “Insect
Counts” window (31) under the main chart. Here you can
specify a time frame (with start and end date and time), du-
ring which the numbers of collected mosquitoes, large ob-
jects, and small objects will be listed. This selection does not
aect the main chart.
Accessing historical data
Data are stored and presented for 15-minute intervals. All
times are local time at the last known location of the trap.
Chart settings
In Chart Settings, you can select for display:
• Insect Types (Mosquitoes, Large Objects, Small Objects)
(21): Press the „Insect Types“ button to see and select your
choice of insect types that will be shown in the chart.
• Date (22)
• Mosquito Sum (sum of counts for periods during which the
counter is on) (23)
• y-Axis range (24)
Main chart
When a trap is called up, today’s data are shown in the main
chart. Click on “< Previous Day”> or >“Next Day >” to navi-
gate day-by-day (25).
Color bars across the chart indicate the times during which
CO2, fan and counter, respectively, were turned on.
Small grey circles on top of the chart indicate the times at
which data connections took place (26).
Clicking on the chart displays the counts for the nearest
15-minute interval.
List
Click on “List” to see trap counts as well as status data dis-
played below the main chart (27). If the battery voltage is
getting low, it can be seen here. Also, the cellular reception
level is indicated; numbers of -113…-100 dB indicate a weak
signal, and data transmissions may become irregular.

Dashboard Warnings
When you log in, you will be presented with a dashboard
with a list showing the status of all BG-Counters 2 in your
account. Any devices with warning status are displayed on
top of the list. The following warnings are indicated with a
red triangle:
Fan column:
A triangle here means one of two conditions have been
detected:
1.) The fan current is low, indicating the fan is not running
even though it is turned on
2.) The fan current is high, indicating a stall (i.e. something is
blocking the fan blades)
Corrective action: Check the fan for proper operation.
Voltage Column:
The low and high supply voltage for the last 24 hours are
displayed.
A triangle here means that the lowest voltage is less than
11.5V, indicating a discharged battery or a solar system that
is not charging properly. The counter will be turned o when
the voltage drops to less than 11.2V in order to protect the
electronics. Once turned o, the counter remains turned o
until the voltage builds up again to 11.8V.
Corrective action may include one or more of the following:
• Charge the battery
• Use a battery with higher capacity
• Make sure solar panels are in full sun
• Check connections on solar controller
• Check solar controller for proper function
You can choose to be notied with an e-mail if warnings are
present. In order to turn on Notications, click on Prole,
then click on Notify me about warnings and click Save.
Trap does not start up
Symptoms:
• No beeps after connecting power
• Fan not working
• CO2valve not clicking
• A blue glow may be visible when looking into the counter
funnel
Cause: No power or wrong polarity
Solution: Check voltage, continuity, and polarity on the po-
wer connection.
Only one or two beeps upon start-up
Symptoms: Counter, fan and CO2 valve are o. No data
transmission.
Cause: Battery is too low.
Solution: Recharge battery, or replace with full battery.
SOS beep during start-up
Symptom: 3 short, 3 long, 3 short beeps
Cause: SD card failure
Solution: Contact support
Checking cellular connectivity
If the counter is in a location with weak cellular signal, the
cellular data connection to the server may be unreliable.
The signal strength at the deployment site can be checked
as follows:
Connect counter to power, then listen for beeps
1.) Immediately: One to four beeps indicating battery vol-
tage
4 beeps: fully charged
3 beeps: partially charged
2 or 1 beep: discharged, counter and trap will not run
2.) After 10-90 seconds, 1-5 long beeps indicating cellular
signal strength (like the bars on a cell phone)
3-5 beeps: strong signal
2 beeps: marginal signal
1 beep: weak signal
Two short beeps: no connection
