The present invention relates to devices for exterminating and/or driving away pests, more particularly insects, preferably Nematocera and Brachycera. The fundamental inventive idea is that of using individual small drops to exterminate or drive away pests. Risk to humans is advantageously avoided.

A radiation unit for a fixation device for fixation of toner material on a printing stock surface for an electrophotographic printing machine, as well as a method for exposure and fixation of toner material on a printing stock surface. Exposure for fixation of toner material occurs essentially indirectly, i.e., the light emitted by the radiation unit is reflected at least once, so that high uniformity and homogeneity of the radiation, efficient energy utilization and avoidance of adverse changes on the printing stock are achieved. A high-energy density, low housing dimensions and independence of the radiation from the employed printing unit are achieved by the fact that the radiation wavelength lies essentially in the ultraviolet spectral range.
