The German Mosquito Control Association (GMCA) conducts insecticide operations in the mosquito-infested floodplains of the Upper Rhine between Bingen and Offenburg.
The German Mosquito Control Association (German: Kommunale Aktionsgemeinschaft zur Bekämpfung der Schnakenplage, or KABS) is an association founded in 1976, with its seat in Speyer (Germany), by 98 bodies (towns, parishes, counties including Baden-Wuerttemberg, 2013 figure) along the upper Rhine to combat the problem of mosquitoes in the area.
KABS employees carry out mosquito control on a 300 km stretch of the Rhine between Bingen and Offenburg over an area of around six thousand square kilometers.
The active substance is mixed with water and distributed with a backpack sprayer by workers on foot, or applied as an ice granulate from the air by helicopter.
In addition, residents of the KABS areas are supplied with Culinex tablets free of charge in order to treat smaller bodies of water such as rainwater tanks and garden ponds which do not contain fish.
