What color are fully fed cat flea larvae?

Fully fed cat flea larvae are dark brown in color. This dark coloration is due to the presence of digested blood from their host, which gives them a distinct appearance compared to unfed larvae, which are typically lighter in color and more translucent. Understanding the physical characteristics of cat flea larvae, including their coloration after feeding, is crucial for pest control professionals in accurately identifying and managing flea infestations.

While the other color choices could represent variations seen in different life stages or conditions, they do not accurately describe the typical appearance of fully fed cat flea larvae. The dark brown color is a telltale sign of their feeding habits and crucial for pest management strategies.
