Nest fleas are fleas that.

Nest fleas are fleas that.

• A. Live on the host
• B. Jump long distances
• C. Transmit rabies
• D. They remain in the nest of the host and they are poor jumpers

Answer: (D)

Nest fleas live in the host’s nest or environment rather than on the animal itself. Because their life cycle is centered in the nest, they tend to stay there and only encounter the host when it comes by, so they don’t need to roam or jump long distances. This makes them poor jumpers, which is exactly what the option describes. It’s the nest-focused lifestyle that defines them, not living on the host or moving quickly between hosts. Also, rabies isn’t transmitted by fleas—rabies spreads through infected saliva via bites, not through fleas.
