Fifteen Years Of Blatta orientalis Infestation Control In The City Of Zurich, Switzerland

In the last 15 years the UPAS achieved successful eradications of the oriental cockroaches in some houseblocks and significant reductions in others. If the monitoring of suspected houseblocks shows activity of cockroaches on sticky traps the UPAS enforces all concerned house owners to have the cockroaches professionally controlled. These houseblocks are monitored yearly during the warm season until no more infestations are found. The UPAS ensures the cooperation of all involved parties to eradicate the cockroaches. Eradication of the oriental cockroach needs persistence and can take more than five years of coordinated control measures. The eradication is important for the urban hygiene and only possible with a common effort of all parties involved.
