Tekko Pro features two insect growth regulators (IGRs): a juvenile hormone analog (JHA), pyriproxyfen, and a chitin synthesis inhibitor (CSI), novaluron. The combination of these active ingredients provides powerful pest control. Pyriproxyfen prevents immature insects from developing into adulthood, rendering them unable to reproduce. Novaluron inhibits or stops the production of chitin, the most important part of the exoskeleton of insects. Essentially, the immature insects cannot molt due to inhibition of the synthesis of a new cuticle. Both active ingredients directly affect immature insects, breaking the cockroach life cycle by stopping molting and reproduction. Additionally, Tekko Pro has shown to reduce egg production in adult cockroaches significantly. Basically, cockroaches cannot grow, they cannot breed, so they cannot survive. Tekko Pro can be used in many application sites, including food-handling areas, hospitals, schools, residential and commercial buildings, transportation equipment, and zoos. Tekko Pro can be used alone or in combination with either a repellent or non-repellent adulticide to provide long-lasting control.
