BG-Counter: new dimension to our understanding

"The BG-Counter allows a standardized approach to gathering relative mosquito population data as all traps can be programed to collect mosquitoes at the exact same time using the exact same methods."
(Hribar et al. 2022)

BG-Counter: high resolution data

"The BG-Counter is extremely useful for providing high resolution data" (Kartinzel & Clifton, Presentation at AMCA 2018)

BG-Counter: less field-work

"BG Counters are a time-saving measure for many inspectors as they will no longer dedicate two hours each day to driving to distant and isolated Landing Rate Counts site"
(Hribar et al., 2022)

BG-Counter: less field-work

"One month of trapping requires less than 3 hours of field-work"
(Kartinzel & Clifton, Presentation at AMCA 2018)

BG-Counter: new dimension to our understanding

"The BG-Counter was able to add a new dimension to our understanding of nightly, weekly and monthly mosquito activity."

BG-Counter 2: a remote monitoring device for mosquitoes

The BG-Counter 2 offers remote monitoring with automated mosquito counting from anywhere in the world at any time. The innovative smart device is placed on top of a Biogents mosquito trap. It differentiates mosquitoes from other insects, counts them, and wirelessly transmits the results to a cloud server. With the BG-Counter App, you can manage your traps and analyze your data.

Optimize the effectiveness of your control activities and therefore save money! Additionally, remote monitoring saves time and manpower, and is thus also more economical:

Collect data ➜ Analyze data ➜ Adapt control measures ➜ Save money

• Automatic mosquito counting
• Trap management from the office
• Comprehensive analysis

• Better treatment timing
• More effective treatment
• Better control for less money

The BG-Counter enables real-time measurements as well as historical analysis of infested areas. Vector control professionals can now establish surveillance programs with unprecedented accuracy and temporal resolution of data, overcoming labour constraints associated with manual inspection.

Automatic mosquito counting

  • The BG-Counter counts mosquitoes while they are sucked into a Biogents trap and differentiates them from other insects or dust particles.
  • Reports of mosquito counts and environmental data (temperature, humidity and ambient light) are remotely sent to the BG-Counter App, where they are available in real-time.
  • Mosquito counts with an accuracy of 90% have been established in field tests when working with CO2.
  • Up to 5 mosquitoes per second can be recorded.

Detailed insights into activity patterns

  • Continuous and high density data allow better control
    The BG-Counter reports mosquito counts every 15 minutes. This high density of data gives you unprecedented insights into mosquito activity patterns: You can find out exactly at which time of the day the mosquitoes are more abundant.
  • Data analysis: Various time ranges and aggregation levels available
    You can analyze daily, weekly, and monthly activity patterns for a variety of time ranges.
  • Diffentiate between day and night
    For aggregated data (daily/monthly/weekly) you can visualize mosquito activity during the night and day separately.

Optimization of control activities

  • Heatmaps: Easy identification of mosquito hotspots
    If you have several BG-Counters, heatmaps show you which traps had a high or low catch rate.
  • Threshold value for the application of control measures
    If you use the trap data for decision making to apply control measures, you can set a threshold value for each of your locations: You get warnings if the threshold is exceeded and a the threshold map shows, which traps were above that threshold.
  • Alternative to human landing rates
    The BG-Counter can be a suitable decision maker for control actions instead of human landing counts as several customers have reported.
    Benefits of using BG-Counters as an alternative to human landing counts:

    • standartized, reliable collection method
    • collections 24/7 at many locations at the same time
    • real-time availability of the data
    • cost-saving
    • time-saving
    • ethically correct

Cost saving

  • Save money on fieldwork
    Very little fieldwork time is required, to have a BG-Counter operating that send you data every 15 minutes, 24/7. One of our customers estimated 3h of field work per trap for a trapping period of 1 month. This saves you a lot of manpower!
  • Save money through optimization
    Optimizing your control activities also reduces costs due to more specific and therefore more effective application.

BG-Counter App

The BG-Counter app is a vital part of the BG-Counter 2. The Counter sends data from the field (mosquito counts, environmental data, geospatial data) to the web-based BG-Counter App. The data base is automatically updated with the data constantly generated in the field.

In the BG-Counter App, you can:

  • Efficiently manage and monitor your traps
  • Set up time schedules for traps and CO2
  • Comprehensively analyze your data

Trap management and monitoring

The dashboard gives an instant overview of locations and helps you to plan your operations, as it includes relevant informaton such as the catch count since last noon, warning icons, signal strength, fan status, and similar.

On the location-specific pages of the dashboard, the App provides catch statistics tables, graphs of catch counts and temperature, and relative humidity, dew point, battery voltage, and ambient light.

The BG-Counter 2 comes with a CO2 pressure regulator and we strongly recommend to use the BG-Counter with CO2!

Adding carbon dioxide

  • Makes the trap highly attractive for all mosquito species
  • Highly increases the overall mosquito catch rate
  • Highly increases the trap’s specificity for mosquitoes (and other blood-sucking insects)

Tipps for saving CO2:

  • Limited hours: To save CO2, you can define time periods in which CO2 is being released, after you have established the daily activity pattern of your local target mosquito species.
  • Selected days: To be able to track possible changes in the activity of day, and night-active mosquitoes, you could also choose one day per week, in which you turn on CO2 for 24 h.
  • Specific pattern: If you always want to keep a close eye on day-and night active mosquitoes around the clock, you might as well choose a schedule of 30 min CO2/ 30 min CO2 off or similar.
  • Lower release rate: We recommend a flow rate of 50 g/h (default setting), as it it the optimum for attracting mosquitoes. In the BG-Counter App Settings, you can also select a lower release rate of 20 g/h or 10 g/h. Keep in mind, that the accuracy of the BG-Counter might decrease with a decreasing flow rate.

It is however important that you keep in mind, that your BG-Counter will only collect reliable data with CO2.


We highly recommend that you use the BG-Lure in addition to CO2 as it acts as an synergist and can multiply your mosquito catch rates:
