Each stylet is only a few hundred micrometers long, yet it combines cutting and sucking functions essential for rapid feeding.. Date latest changes:
How long do fleas survive without food?
Flea eggs are laid on the host or in the surrounding environment and require specific conditions to develop. Under optimal temperature (21‑27 °C) and humidity (70‑80 %), eggs hatch within 2‑5 days. If the environment is cooler or drier, the incubation period extends up to 10 days, and prolonged exposure to unfavorable conditions can halt development entirely.. Date latest changes:
