Backyard tiger mosquito control

About Biogents

Biogents USA is an affiliate of the Biogents AG that is located in Germany. Biogents’ scientists develop and produce mosquito traps and mosquito attractants.

“How does a mosquito find its host? And what can you do about it?”

Answering these seemingly simple questions was the work of Dr. Martin Geier and some of his collegues at the Institute of Zoology at the University of Regensburg in Germany. More than twelve years were put into both the analysis of the composition of scents and odors that were attractive to mosquitoes and finding the key factors that influence the behavior of these important disease vectors.

The primary motivation behind this research was the application of the results: to develop better methods to control mosquitoes in an intelligent, environmentally safe, and targeted manner. In 2002, Dr. Geier and his collegue Dr. Andreas Rose founded Biogents.

Today, Biogents AG is an innovative company on the forefront of mosquito control research with an excellent reputation. The company is home to 27 staff members and is composed of two business units that complement each other: the development and production of highly efficient mosquito traps and a contract research and development sector in the field of mosquito repellents and related products.

Research and development (R&D) remains a strong point of the company: Biogents’ scientists continue to develop and refine the expertise and the products the company offers.

In the product sector, Biogents develops and produces patented mosquito traps which exhibit capture rates that are multiple times better than those of other designs. That is why, for example, Biogents traps are being investigated as a means for combating dengue fever as well: a project that is supported by the World Bank, the Bill-und-Melinda-Gates foundation, and state agencies in Brazil.

Today, the spectrum of Biogents mosquito traps ranges from devices that are used by scientists, health-care specialists, and other professional users worldwide (BG-Sentinel) to those that are used by homeowners (BG-Mosquitaire).

In our contract research sector, we offer a broad range of methods that can be used to investigate the different modes of action of repellent products: mosquito repellent lotions and sprays, special textiles, repellents acting over a distance, and similar products. Here, Biogents advises, researches, and develops by contract or carries out product comparisons, and provides proofs of effectiveness.

In the meantime, excellent contacts with formulation chemists enabled Biogents to offer also the complete development of mosquito agents.
