Oriental rat flea
Quick Summary
The Oriental rat flea (Xenopsylla cheopis) is an insect that acts as a parasite, feeding on the blood of mammals and birds. Fleas are small, wingless, and known for their ability to transmit diseases, most notably the Black Death (bubonic plague) during the Middle Ages.1
The Oriental rat flea is considered a highly efficient carrier of plague. When rats infected with plague bacilli die, their hungry fleas seek new hosts, including humans, thus transmitting the disease. Fleas are also implicated in the spread of murine typhus, another disease transmitted by rodents.12
Fleas undergo a life cycle with four stages: egg, larva, pupa, and adult. The larvae feed on organic debris, while adults require blood meals. Some species can remain in the pupal stage until a host is present.1

It was then demonstrated definitively that rat fleas would infest humans and transmit plague through their bites. With that, massive rat-proofing measures were instituted worldwide in maritime vessels and port facilities, and insecticides were…
