Fleas

From Cow
Adult Pulex irritans

Fleas are a common parasite of cattle worldwide.

Common fleas found on cattle include:

Fleas on cattle have been known to transmit Rickettsia spp protozoa.

The life cycle of fleas begin with eggs deposited on the coat of cattle, where they drop onto pasture or flooring of barns. The eggs eventually hatch into larvae which feed on soil matter. The larvae eventually pupate and cocoons can be found in soil and under vegetation. Adult fleas eventually emerge and begin feeding on cattle.

Depending on temperature and humidity, the entire life cycle of the cat flea can be completed in as little as 12–14 days or can be prolonged for up to 350 days[1].
