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."
(Kartinzel & Clifton, Presentation at AMCA 2018)

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.

The BG-Counter counts the mosquitoes and sends the signal to a web server.

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

  • 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.

Optimization of control activities

The BG-Counter can be a suitable decision maker for control actions instead of human landing counts.

This brings several benefits:

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

Cost saving

  • 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 save you a lot of manpower!
  • Optimizing your control activities also reduces costs.

Technical details

The patented insect sensor consists of arrays of infrared LEDs and light detectors that provide reliable and sensitive detection and differentiation of moquitoes from other objects entering the trap.

The heart of the BG-Counter 2 is a highly integrated printed circuit board which incorporates:

  • An infrared sensor
  • environmental sensors for temperature, relative humidity and ambient light
  • a cellular module for communication with the web server
  • an SD card for onboard data storage, fan and CO2 valve control
  • two powerful microprocessors for control and communication

BG-Trap Station

Biogents‘ BG-Trap Station is a robust and ideal shelter for your BG-Counter 2.

The BG-Trap station

  • is made of stainless steel
  • protects your BG-Counter 2 from environmental conditions
  • can be attached to any type of terrain

Solar power

You can run the BG-Counter 2 on solar power. In this way, remote monitoring get’s even easier!

In the video below, Catherine Pruszynski from the Floria Keys Mosquito Control District shows how to set up the BG-Counter 2 with a solar panel.

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.

The database for storage of mosquito counts, geospatial, and environmental data (temperature, humidity, and light), is automatically updated. The data can be exported to Excel.

In the BG-Counter App, you can:

  • Manage your traps
  • Set up time schedules for traps and CO2
  • Comprehensively analyze your data

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

Adding carbon dioxide

  • highly increases the overall mosquito catch rate
  • highly increases the trap’s specificity for mosquitoes (and other hematophagous insects)
  • makes the trap highly attractive for all mosquito species

Tipps for saving CO2:

  • In order 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.
  • If you want to keep a close eye on the 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.

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:
