How Temprid FX Insecticide Works Temprid FX contains imidacloprid, a poison that negatively affects insects. It disrupts the nervous system and prevents the pests from feeding and grooming, which leads to their death. It also contains beta-cyfluthrin, a synthetic pyrethroid that mimics natural pyrethrum in the wild. It works quickly after ingestion or contact and causes paralysis, leading to the insect's death.
