7A Pest Exam Questions and Answers Already Passed Integrated Pest Management a process that utilizes inspections and periodic monitoring to determine if any type of treatment is needed to reduce pest populations to tolerable levels Four Steps in an Integrated Pest Management Program 1. Inspect the site for pest problems. || 2. Set pest action thresholds. || 3. Apply pest management procedures. || 4. Monitor the pest management program (post-treatment) Action Threshold the level of pest infestation which requires initiating a control strategy Pest Exclusion best way to manage pests, denying entry into buildings through sealing gaps, installing proper door thresholds etc. some companies do this work, while other's leave it up to the client Pest Habitat Manipulation a control strategy that denies pests access to food, water, and shelter, usually through concentrated sanitation efforts. factors could include temperature and humidity. critical for controlling cockroaches and rodents. take care of filthy conditions Pest Removal most direct method of managing pest populations. involves lethal trapping (most used) and disposal; live trapping (wildlife and animals) and removal; and direct removal techniques (such as vacuuming cockroaches) Contact Insecticides and Stomach Poisons contact insecticides penetrate through insect body covering; applied directly to insect or as residue on surface for insect to crawl through. stomach poisons ingested by insect during feeding or grooming Residual Insecticides and Non-Residual Insecticides involves length of time a pesticide will last. residual insecticides may persist for weeks or longer. non-residual pesticides break down quickly after treatment Desiccants part of inorganic insecticides. disrupt the water balance (such as rapid water loss) of insects that contact them. low hazard to non-target organisms and not known to develop resistance Pyrethrins part of botanical insecticides, which are plant-derived. pyrethrins are constituents of pyrethrum. interrupt the normal transmission of an insect's nerve impulses. used with synergists, provide quick knockdown with little residual activity. used at low rates as flushing agents during inspection to improve detection of insects Synthetic Pyrethroids part of synthetic organics, which are laboratory-produced and contain carbon. mimic the action of pyrethrins meaning they interfere with the transmission of nerve impulses. quick knockdown activity. engineered to be more stable and persistent. Insect Growth Regulators part of synthetic organics, which are laboratory-produced and contain carbon. chemicals that mimic the juvenile growth hormone and prevent the immature insect from molting into the adult stage and, in doing so, disrupt the insect's life cycle by preventing it from reproducing. chitin synthesis inhibitors often grouped with IGRs so the insects do not molt. very low hazard to non-target animals. insect-specific Baits placement makes them inaccessible to people and pets. offer ease of placement and are odorless. in order to be effective, target pest must consume bait. less attractive to pests if unsanitary conditions provide alternate food source Dusts provide the longest residual activity of the various insecticide formulations, provided they are carefully applied to dry areas. provide excellent coverage within cracks, crevices, and other voids. may be used around electrical outlets.
