Biogents offers the first commercially available high tech remote monitoring device for mosquitoes, the BG-Counter 2.

The device is place on top of a BG-Sentinel or a BG-Pro mosquito trap. The BG-Sentinel was invented in 2004 and has become is one of the most used mosquito traps on the professional market. It has been used by researchers and health authorities world wide. There are hundreds of articles published in peer-reviewed journals about this trap. Click here for a collection of scientific studies. The BG-Pro is a new modular trap type that is at least as efficient as the BG-Sentinel trap, but has several operational advantages, as pointed out in a recent study.

The BG-Counter 2 automatically differentiates mosquitoes from other insects entering the trap, counts them, and wirelessly transmits the results to a cloud server. Via an web application you can manage your BG-Counter and get insights into daily activity patterns, adult density indices, population dynamics and effectiveness of your control activities.

The BG-Counter 2 enables real-time measurements as well as prediction models and 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 2

  • reports mosquito counts remotely from everywhere in the world to an internet web page
  • samples local environmental data such as temperature, relative humidity, and ambient light
  • lets you manage the trap and the application of CO2 remotely
  • reduces costs associated with manually checking mosquito traps

The BG-Counter 2 is the next generation version of the BG-Counter. It offers several improvements over the previous model such as

  • an internal antenna
  • improved protection against corrosion and environmental influences
  • a better insect classification accuracy through improved algorithms
  • a 4G Cellular Communication Module that works on the LTE cellular network and is not affected by eventual sunset of a 3G network.
  • a BG-Pro trap instead of a BG-SentinelBG-Counter transmits automatically mosquito counts to a web application. It ideally works together with the BG-Trap Station.

Features in Detail

  • The BG-Counter 2 counts mosquitoes while they are sucked into a Biogents trap and differentiates them from other insects or dust particles. Mosquito counts with an accuracy of 90% have been established in field tests when working with CO2 as an attractant. Up to 5 mosquitoes per second can be recorded. The data can be accessed by a web application and alerts are retrieved in real-time.
  • The BG-Counter 2 can also sample local environmental data such as temperature, humidity and light.
  • The effectiveness of control measures can be validated immediately.
  • A web application allows you to remotely switch the traps on and off. It also allows you to set up varying time schedules to run the traps and set up application times of CO2.
  • The BG-Counter 2 minimizes maintenance effort: The can run on solar power and is self-sustaining. It is robust and well protected against weather.
  • The BG-Counter 2 includes:
    1x mobile module,
    1x SIM card for data transmission,
    1x fan adapter cable,
    1x battery cable,
    1x mains supply,
    1x CO2 pressure reducing regulator with output pressure of 2 bars,
    1x CO2 tube,
    1x BG-Pro Counter version (1x funnel net, 2x catch bag, 1x inner cylinder with upper part and lower part with 12V fan, 1x trap body, 1x carrying bag, 1x tripod)

Web-based Access

BG_Counter_Web_applicationThe BG-Counter 2 system is supported by a web-based database for storage of mosquito counts, geospatial and environmental data. The data base is automatically updated with the data constantly generated in the field.

The data can be accessed, displayed and analyzed by the end user in a cloud-based dashboard. They can also be exported to Excel at the push of a button. The intuitive graphical user interface can be accessed from PCs as well as smart- phones and tablets.

The image on the right side depicts a combination of several displays of the user interface.

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-Counter 2 and BG-Trap Station: the Optimal Combination

BG-Trap Station
Biogents‘ new 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

The BG-Counter ideally works together with the BG-Trap Station.

This article is about Biogents traps and BG-Counters to be deployed across UAE

440 smart mosquito traps to be deployed across UAE

Tadweer has developed an effective, efficient and sustainable way to trap mosquitoes.
More than 400 solar-powered smart traps will be installed across the country from February 1 to catch mosquitoes and thus keep a check on the outbreak of diseases like malaria, dengue, Yellow Fever and West Nile Virus, an official from Abu Dhabi Waste Management Centre (Tadweer) said.

mp4 video   Rise of the machines: BG-Counters’ expanding role in CMCD’s mosquito surveillance program

Collier Mosquito Control District initiated its BG-Counter program in 2017 with 10 traps. As of the 2020 field season, we had one of the largest BG-Counter networks in the country, with 27 permanent traps placed throughout the District. This presentation will discuss the District’s experience with this technology, including an assessment of labor inputs vs. outputs, as well as the lessons we’ve learned in scaling up our program. We’ll also introduce side-by-side data from our weather station pilot program, which was designed to enhance the value and utility of the information generated by the BG-Counters.
