Insecticide for combating walking and flying insects, e.g. cockroaches (Blattella germanica, Blatta orientalis), ants, fleas, flies, etc. both indoors and outdoors. The preparation affects the nervous system of insects - it acts quickly on contact or when swallowed. It offers reliable and long residual action, even up to 6 months. This is due to the microcapsules that release the active substance at a very slow rate. In addition, the microcapsules stick to the insect's body which increases the insecticide's potential.
