General Pest Control(ODA Category 10A)
Areas covered by exam:
Pest Identification
Biology of Major Pest Groups
Control Approaches
Pesticide Types, Modes of Action, & Application Techniques
Reading & Understanding Label Instructions
Groups Included in “General Pest”
Cockroaches Pantry Pests (grain & flour pests)
Nuisance Pests (ants, bees, wasps, flies)
Fiber & Paper Pests (carpet beetles, clothes moths, silverfish, booklice)
Structural (carpenter ants & bees - not termites)
Occasional Invaders (spiders, centipedes, millipedes, earwigs, mites, etc.)
Parasites (fleas, ticks, lice, bed bug)
Rodents
Characteristics of the PhylumArthropoda
The segmented bodies are arranged into regions, called tagmata (e.g., head, thorax, abdomen).
The paired appendages (e.g., legs, antennae) are jointed.
They posses a chitinous exoskeletion that must be shed during growth.
They have bilateral symmetry.
The nervous system is dorsal (belly) and the circulatory system is open and ventral (back).
Arthropod Groups (taxa)
The arthropods are divided into two large groups that exist today:
The Chelicerates
and
The Mandibulates
Chelicerate Arthropod Characters:
Pincher-like mouthparts - chelicerae - and pedipalps
NO antennae
Two body regions, usually - cephalothorax & abdomen
Four pairs of legs
Horseshoe crabs and arachnids are only living groups
Mandibulate Arthropod Characters:
Mouthparts are mandibles - normally chewing sideways
One or two pairs of antennae
Various body region arrangements - cephalothorax & abdomen / head & trunk / head, thorax & abdomen
Variable leg numbers
Insects, crustaceans & myriapods
Orders of Arachnids
Scorpionida - scorpions
Pseudoscorpionida - false scorpions
Phalangida - daddy-long-legs or harvestmen
Acari - mites & ticks
Araneida - spiders
pedipalps &chelicerae

Myriapods
Millipede (Diplopoda)
Two pair of legs per visible segment, attached under body.
Centipede (Chilopoda)
Pair of fangs under head, one pair legs per visible segment - attached to side of body.

No fangs, no eyes, legs attached to side of body.
[one pair of antennae, head & trunk regions, trunk with many pairs of legs]
Millipede (Diplopoda)

Garden centipede (Symphyla)
Classes of Crustacea(mostly marine, fresh water, a few terrestrial)
(all have two pair of antennae, five or more pairs of legs, segmented abdominal appendages, head & trunk or
cephalothorax & abdomen body arrangement, have gills)
Isopoda - sowbugs or pillbugs
Amphipoda - sand fleas, amphipods
Cirripedia - barnicles
Decapoda - crabs, lobster, shrimp
several other minor orders
Crayfish cephalothorax(Decapoda)
Sowbug (Isopoda), a terrestrial crustacean
Class Insecta(all have one pair of antennae, a head, thorax &
abdominal regions, three pair of legs, adults usually have wings, use trachea)

Native Species Woods roach
Cockroach SpeciesSpecies Size Life Span Preferred Habitats
American Large
1.3-2.1
1.5-2.0 yr Needs water, commonly breeds in sewer systems & underground utility systems.
Oriental Medium
1.0-1.3
1.0-3.0 yr Prefers high humidity areas, can withstand freezing temps, often in basements, garages, crawl spaces.
Brownbanded Small
0.5-0.6
90-280 days Can withstand dryer conditions, often lives in electrical equipment, attaches egg cases anywhere.
German Small
0.4-0.6
2-6 months Retains egg case until hatching, needs warmth, & water, often around food processing areas.
Cockroach SpeciesWoods Roach
Native North American species Attracted to lights at night Reduce dense outside vegitation Exclusion or parameter sprays useful in control
Cockroach Management
Monitor (sticky traps, flushing agents, determine extent of population)
Sanitation Exclusion (caulking, parameter sprays)

Reproductive Strategy (single or multiple queens)
Nuisance Ants
Common Ohio Ants
Carpenter Ant
Characterized by having polymorphic workers
Nest by excavating decaying wood or voids (they don’t eat the wood, they cast out wood shavings!)
Major nests in trees (satellite nests in buildings where water is available)
Most active at night (best time to find colony(ies) is at night!)
Carpenter Ant Management
Locate nesting site(s) (outside and/or inside - look at night, repair water damaged structures)
Prune back trees and shrubs touching infested building
Seal external entry sites
Exclude with parameter sprays
Treat colonies (injection, dusts) (baiting is rarely successful)

Ant Management
Identify species!
Locate nesting site (outside and/or inside)

Cat, dog & rat fleas are most commonly found (cat flea is, by far, the most common on dogs and cats!)
Adults suck blood for food
Eggs drop from host
Flea larvae feed on organic debris & blood excrement from adult fleas
Pupae may remain dormant
