COLORADO PEST CONTROL CATEGORY 304 STATE
TEST (QS)
Pest - Answer -Unwanted organisms that are a nuisance to man/animals and can
cause injury to humans, animals, plants, structures, or possessions. Can be an insect,
rodent, fungus, weed, or other organisms.
Sequence of Pest Control - Answer -Inspection, Diagnosis, Prescription and
Application, Evaluation
Inspection - Answer -Step in the pest control sequence - Includes asking customers
questions and examining the building thoroughly. Look for harborage areas, conducive
conditions (moisture, heat, etc), food/water sources, means of entry, and evidence of
infestations (damage, droppings, etc)
Diagnosis - Answer -Step in the pest control sequence - Includes identification of the
pest and any facts contributing to infestation.
Prescription and Application - Answer -Step in the pest control sequence - what, how,
when, and where to use control techniques that correct the problem.
IPM - Answer -Integrated Pest Management - an approach where habitat modifications,
cultural controls, pest control devices, and pesticides are integrated and used together.
Exclusion - Answer -Blocking points of entrance for pests.
Evaluation - Answer -Step in the pest control sequence - periodic inspections to assess
effectiveness of prescribed plan.
Hand Carried Compressed Air Sprayer - Answer -The most basic piece of equipment,
used on a variety of insects; includes a tank, pump, tube that carries spray to hose,
hose that connects to tank, a valve to control flow, and a nozzle to distribute spray.
Canned Aerosol Pesticides - Answer -These products produce an aerosol or fog
droplet that floats in the air for a period of time and then settles. The droplets kill pests
on contact or if insects fly/move into treated area.
Aerosol and Fog Generators - Answer -Break liquid pesticides into aerosol droplets
through either mechanical means (cold fogging) or heat (thermal fogging).
Cold Foggers - Answer -Break insecticide into aerosol-sized droplets and propel them
into the air as a "fog". Examples are ULV and ULD. Generally used to fill rooms and
small warehouses to kill flying and exposed insects. Fogs do not enter cracks/crevices.
, Thermal Foggers - Answer -Us heat to vaporize oil-based insecticide formulations,
operating similarly to cold foggers but with smaller droplet size.
REI - Answer -Re-entry interval, the time set before people or pets reoccupy treated
areas.
Dusters - Answer -Used to apply dust, pesticides in dust sit on surface and accumulate
on insect body parts. They are either absorbed or ingested when insects groom
themselves.
3 types of residual applications - Answer -General (application to broad expanse of
surfaces), Spot (application to limited area where insects are and will not ordinarily be
contacted by workers), and Crack and Crevice (application of small amounts where
insects hide like voids and entry points).
SDS - Answer -Safety Data Sheet, formerly MSDS, technical bulletin that provides
workers and emergency personnel with proper procedures for handling or working with
a given substance.
Absorption - Answer -Movement of chemical into a plant, animal, or person. Number
ons source of pesticide exposure for operators.
PPE - Answer -Personal Protective Equipment, keeps pesticides from getting on
skin/mouth/eyes/lungs.
Wettable Powders (WP) - Answer -non-soluble pesticide is coming with a finely ground
material like clay and other ingredients to improve mixing. Form a suspension solution
when mixed with water that must be agitated during application. Can be abrasive to
equipment and typically leave a residue.
Dry Flowables or Water Dispersible Granules (DF or WDG) - Answer -Similar to WP
but in form of granules to be mixed with water, require agitation.
Soluble Powders (S or SP) - Answer -Pesticides that dissolve with water after mixing to
form true solution, do not require agitation and are non-abrasive.
Emulsifiable Concentrate (EC) - Answer -Pesticide that is soluble in an organic solvent
but not in water; when combined with water a milky emulsion is formed and must be
kept agitated; non-abrasive, but can deteriorate rubber and hoses; may damage
surfaces; easily absorbed through skin
Flowables (F) - Answer -Consists of finely ground pesticides combined with a liquid
solvent and emulsifiers; when mixed w water they form a suspensions solution similar to
WP; must be agitated, may be abrasive, and leave residue.
