Connecticut Category 7F Mosquito and Biting Flies Pest Control Exam
Below is a summarized exam coverage for the Connecticut Category 7F Mosquito and Biting Flies Pest
Control Exam, followed by 250 randomized, scenario-based MCQs with answers and italicized
rationales. This is based on the CT DEEP Supervisory Certification requirements and standard mosquito
control practices relevant to Connecticut.
Summarized Exam Coverage — CT Category 7F
Category 7F certification authorizes the holder to supervise the control of mosquitoes and biting flies in
Connecticut. Certification is issued by the CT Department of Energy and Environmental Protection (CT
DEEP). The exam covers:
• Mosquito Biology & Life Cycle: Egg, larva (4 instars), pupa, adult stages; breeding habitat
preferences; species identification relevant to CT
• Public Health Significance: Mosquito-borne diseases (West Nile Virus, Eastern Equine
Encephalitis, Triple E); disease surveillance and reporting; CT DEEP/DPH coordination
• Biting Flies: Identification and control of black flies (Simuliidae), deer flies (Chrysops), horse flies
(Tabanidae), stable flies, biting midges (Ceratopogonidae)
• Integrated Pest Management (IPM) & Surveillance: Larval mosquito surveillance (dipping);
adult mosquito surveillance (light traps, CO₂ traps, gravid traps); landing rate counts; record
keeping; action thresholds
• Source Reduction & Water Management: Drainage; ditching (Open Marsh Water
Management); filling; stormwater management; elimination of standing water
• Larvicides: Bacterial larvicides (Bacillus thuringiensis israelensis - Bti, VectoBac; Bacillus
sphaericus); insect growth regulators (methoprene - Altosid); surface films (monomolecular
films - Agnique, mosquito dunks/bits); petroleum oils (GB-1111); selection by habitat type;
application equipment
• Adulticides: Pyrethroids (permethrin, resmethrin, sumithrin, deltamethrin); organophosphates
(malathion, naled); ULV (ultra-low volume) ground and aerial application; fogging; thermal fog
vs. ULV; droplet size (10-20 microns for adulticides); timing (evening/night when mosquitoes
active)
• Avian and Equine Considerations: Birds as amplifying hosts; mosquito feeding preferences
(ornithophilic vs. mammalian); vaccination of horses (EEE, WNV); CT DEEP surveillance, import
requirements
• Connecticut Regulations: CT DEEP authority to enter lands and conduct mosquito surveys;
standing water prohibitions in municipalities with >100,000 population following WNV death; CT
DEEP Public Health Code
• Equipment & Calibration: ULV cold aerosol generators; thermal foggers; granular spreaders;
hand-held sprayers; calibration formulas (acres treated, GPA, ounces per acre, dilution); nozzle
selection; droplet size analysis
• Safety & PPE: Pesticide handling; label comprehension (EPA Reg. No., signal words, PPE
requirements, REI, PHI); respirator selection and fit testing (NIOSH-approved); heat stress

prevention; environmental protection (avoid non-target drift, bees, aquatic life); spill
containment and response
• Pesticide Formulations: EC (emulsifiable concentrate), ULV concentrate, granules, water-
dispersible granules, SC (suspension concentrate), mosquito dunks/briquettes
• Record Keeping: Pesticide application records (date, time, location, target pest, pesticide used,
rate, wind speed/direction, temperature); notification of bee keepers; CT DEEP reporting
requirements
250 Randomized, Scenario-Based MCQs
1. The CT DEEP has the authority to enter private property to inspect for mosquito breeding sites under
which statute?
A) CGS § 22a-45b
B) FIFRA Section 18
C) CT Public Health Code § 19a-93
D) CGS § 22a-66 (Aquatic Pesticide Control)
E) EPA's Endangered Species Act
Answer: A
*Rationale: Connecticut General Statutes Section 22a-45b (formerly § 19a-93) grants the Commissioner
of Energy and Environmental Protection the authority to enter lands to survey for mosquito breeding.*

2. Under CGS § 22a-45b(c), in municipalities with a population over 100,000 that have experienced a
documented human death from West Nile virus, what is prohibited on private property?
A) Using insect repellent
B) Standing water that creates a risk of mosquito-borne illness
C) Planting ornamental grasses
D) Feeding wild birds
E) Operating air conditioners during summer months
Answer: B
Rationale: The statute explicitly prohibits standing water that creates a risk of mosquito-borne illness in
such municipalities, with enforcement by the CT DEEP.
3. What is the primary larval surveillance method used by mosquito control personnel in Connecticut?
A) Light traps with CO₂
B) Dipping with a standard dipper
C) Gravid traps
D) Landing rate counts on human bait
E) Sticky traps placed near barns
, Page 4 of 143
Answer: B
*Rationale: Larval surveillance (dipping) is conducted using a standard dipper (350-ml or 500-ml dipper)
to sample water for mosquito larvae.*
4. Bacillus thuringiensis israelensis (Bti) is classified as which type of larvicide?
A) Organophosphate
B) Pyrethroid
C) Insect growth regulator
D) Bacterial toxin
E) Carbamate
Answer: D
Rationale: Bti is a naturally occurring soil bacterium that produces a protein toxic to mosquito and black
fly larvae.
5. In Connecticut, what is the standard target droplet size for ULV adulticide applications?
A) 50-100 microns
B) 150-200 microns
C) 5-15 microns
