Management QUESTIONS AND
ANSWERS




Integrated Pest Management - ANSWER-A process that utilizes inspections and periodic monitoring to
N N N N N N N N N N N N




determine if any type of treatment is needed to reduce pest populations to tolerable levels. This includes
N N N N N N N N N N N N N N N N N




combinations of pesticide and nonchemical control methods that are environmentally, socially, and
N N N N N N N N N N N N




economically compatible with public expectations.
N N N N N




What are the four steps in an integated pest management program? - ANSWER-1.) Inspect the site for pest
N N N N N N N N N N N N N N N N N




problems.

2.) Set pest action plan thresholds.
N N N N N




3.) Apply pest management procedures
N N N N




4.) Monitor the pest management program (post-treatment).
N N N N N N




Action Threshold - ANSWER-The level of pest infestation which requires initiating a control strategy.
N N N N N N N N N N N N N




Pest exclusion - ANSWER-- The best way to manage pests is to deny them entry into buildings in the first place.
N N N N N N N N N N N N N N N N N N N N




It can be labor-intensive and potentially costly, it is sometimes the only solution to a pest problem.
N N N N N N N N N N N N N N N N N

,-Examples: Keeping pest out of builidings by sealing gaps and installing proper door thresholds, or by installing
N N N N N N N N N N N N N N N N




screens, chimney caps, door closure devices, etc.
N N N N N N N




Pest habitat manipulation - ANSWER-- A control strategy that denies pest access to food, water, and shelter,
N N N N N N N N N N N N N N N N




usually through concentrated sanitation efforts. It also might include temperature and humidity
N N N N N N N N N N N N




modification to make a structure less suitable to the pest.
N N N N N N N N N N




- Example: Pests such as cockroaches and rodents do so well in filty conditions that it enhances their
N N N N N N N N N N N N N N N N N




reproductive rates, but by changing up the environment through the means of sanitation one can impact
N N N N N N N N N N N N N N N N




these pests livelihood.
N N N




Pest removal - ANSWER-- The most direct method of managing pest populations.
N N N N N N N N N N N




- Examples:
N N




~Lethal trapping and disposal (snap traps for rat and mice; multiple catch traps and glue boards for mouse
N N N N N N N N N N N N N N N N N N




control; sticky traps for insect control; insect light traps and jar traps for flying insects)
N N N N N N N N N N N N N N N




~ Live trapping and removal ( commonly used to remove nuisance wild life as part of a management program.
N N N N N N N N N N N N N N N N N N N




Requires skill and training and must comply with fedral and state regulations)
N N N N N N N N N N N N




N ~ Direct removal techniques (vacuuming)

How do contact insecticides ? - ANSWER-Penetrate through the insect body covering. These materials may be
N N N N N N N N N N N N N N N




applied directly to the insect or as a residue on a surface for the insect to crawl through.
N N N N N N N N N N N N N N N N N N




How do stomach poisons work ? - ANSWER-They are ingested by the insect during feeding or grooming.
N N N N N N N N N N N N N N N N




Residual insecticides - ANSWER-Insecticides may persist for weeks or longer.
N N N N N N N N N




Non-residual insecticides - ANSWER-Insecticides break down quickly after treatment.
N N N N N N N N




Desiccants - ANSWER-These types of insecticides disrupt the water balance (e.g., cause rapid water loss) of
N N N N N N N N N N N N N N N




insects that contact them.
N N N N

, Pyrethrins - ANSWER-They interrupt the normal transmission of an insect's nerve impluses. They are
N N N N N N N N N N N N N




formulated to provide a quick knockdown with little residual activity.
N N N N N N N N N N




Synthetic pyrethroids - ANSWER-They interfere with the transmission of nerve impluses and have quick
N N N N N N N N N N N N N




knockdown activity, but they are engineered to be more stable and persistent.
N N N N N N N N N N N N




Insect growth regulators - ANSWER-Chemicals that mimic the juvenile growth hormone and prevent the
N N N N N N N N N N N N N




immature insect from molting into the adult stage and, in so doing, disrupt the insect's life cycle by preventing
N N N N N N N N N N N N N N N N N N N




it from reproducing.
N N N




Chitin synthesis inhibitors - ANSWER-Often grouped together with IGRs. Chemicals are used to treat the
N N N N N N N N N N N N N N




(chitin) component of the insect exoskeleton and immature insects to prevent them from molting into the
N N N N N N N N N N N N N N N N




next stage of development.
N N N N




Baits - ANSWER-Advantages: They are available in ready-to-use bait stations and as gels that can be applied
N N N N N N N N N N N N N N N N




into insect harborages with a syringe-type bait guns. Their placement makes them inaccessible to people and
N N N N N N N N N N N N N N N N




pets. They offer ease of placement and are odorless.
N N N N N N N N N




Disadvantages: In order to be effective the target pest must consume the bait, and they are less attractive to
N N N N N N N N N N N N N N N N N N




pests if unsanitary conditions provide alternative food sources.
N N N N N N N N




Dusts - ANSWER-Advantages: They provide excellent coverage within cracks, crevices, and other voids, and
N N N N N N N N N N N N N




may be used around eletrical outlets.
N N N N N N




Disadvantages: If applied carelessly, it can drift into nontarget areas. N N N N N N N N N




Granules - ANSWER-Advantages: Formulated for exterior applications where longevity under wet, hot
N N N N N N N N N N N




conditions is desirable.
N N N N




Disadvantages:
