Any substance or mixture of substances intended for preventing, destroying, repelling or controlling any of the numerous small invertebrate animals generally belonging to the class Insecta.

Section 132B describes, generally speaking, the investigation powers relating to operating electronic equipment. Section 132C describes investigation powers that relate to seizing evidence that relates to certain offences and civil penalty provisions.
