Norway rats require a daily water source to survive, often living near water or in areas with high moisture. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 8:
Rodents) notes this as a key characteristic, making water sources a target for control. Option B (house mouse) and Option C (deer mouse) can survive on moisture from food and do not require a daily water source.

Swarming termites and ants can be distinguished by physical characteristics. Termites do not have a waist, as their body is broad and straight, while ants have a narrow, pinched waist. Additionally, termites have straight antennae, whereas ants have bent (elbowed) antennae. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Termites vs. Ants) highlights these differences. Option A (bent antennae) applies to ants, not termites. Option C (narrow waist) also describes ants, not termites.

Lyme disease is transmitted by the blacklegged tick, and both the nymph and adult stages can transfer the disease to humans if infected with the bacterium Borrelia burgdorferi. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7: Ticks) notes that nymphs are more likely to transmit due to their small size and longer feeding time, but adults can also transmit.
Option A (nymph only) and Option C (adult only) are incorrect, as both stages are capable.

Cockroaches undergo gradual metamorphosis, which includes three stages: egg, nymph, and adult.
Nymphs hatch from eggs and resemble smaller, wingless adults, molting several times before reaching maturity. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter 7:
Cockroaches) confirms this life cycle for common species like the German cockroach. Option B (complete metamorphosis) applies to insects like flies or beetles. Option C (total metamorphosis) is not a recognized term and is incorrect.

Bottle or blow flies are known for their metallic green or blue color, which distinguishes them from other flies. TheGeneral Pest Management: Guide for Commercial Applicators - Category 7A(Chapter
7: Flies) describes these flies as common in structures, often attracted to decaying organic matter.
Option A (cluster flies) are dull grayish-brown and often found in attics. Option B (house flies) are gray with black stripes, not metallic.
