How far can flea larvae travel?

Flea larvae are known to have limited mobility, typically being able to travel just a few inches in their early stages of development. They primarily remain in the vicinity of their breeding and feeding sites, such as nests or carpets, where they feed on organic material, including dried blood and skin particles. The correct choice reflects this behavior, as flea larvae primarily stay close to their original environment and do not wander far, generally moving less than an inch from their hatching point.

Other options suggest a greater range of movement, which does not align with the biological and behavioral characteristics of flea larvae, as they are not equipped to cover longer distances at this stage.
