The efficiency of mechanical, biological and / or chemical control methods can be increased considerably by: the cockroaches to be controlled are lured to the control devices or the insecticidal agents by means of suitable attractants such as bait, certain color arrangements, fragrances, pheromono and the like

(1985) 499-503) Diese Publikation, in der 57 Carbonsauren als Schabenkot-Inhalts- stoffe beschrieben werden, enthalt keine praktisch verwertbaren Vorschlage zur Scha- benbekampfiing. In der europaischen Anmeldung EP 588 203 werden in sehr allgemeiner Form Mischungen von mindestens 2 Carbonsauren oder Carbonsaurederivaten beschrieben, die als Schabenlockstoffe eingesetzt werden können Eine experimentelle(1985) 499-503) This publication, in which 57 carboxylic acids are described as cockroach droppings, does not contain any practically usable suggestions for cockroach control. European application EP 588 203 describes in very general form mixtures of at least 2 carboxylic acids or derivatives of carboxylic acid which can be used as cockroach attractants
Überprüfung der dort beschriebenen Kombination zeigte jedoch nur unzureichende Ergebnisse Dies führte auch zu einer frühzeitigen Aufgabe dieser PatentanmeldungExamination of the combination described there, however, showed insufficient results. This also led to the early abandonment of this patent application

Surprisingly, it was found that the special combination of at least 3, in particular 6, of these acids have an additive attracting action on cockroaches. In the combination according to the invention, the acids (I) to (VI) can be used as such or in the form of their salts or mixtures thereof Salts with free carboxylic acids are used.
