Although modern medicine has diminished the chances of such epidemics, the flea has remained a major problem in regions, where there are high rodent populations. This makes oriental rat flea treatment a very crucial measure to control pests in residential, warehouse and community houses. We think that learning about the history, behavior and identification of this flea can make people remain safe and ready at saynopest.

Oriental Rat Flea Historical Link with Plague

The Oriental Rat Flea has a close connection with the one of the most lethal pandemics of all time, the bubonic plague or the Black Death. The 14 th century Europe witnessed the loss of millions of people due to the spread of the bacterium Yersinia pestis by these fleas that rats carry. 

The idea of an outbreak persisted in subsequent centuries, such as the 19th century plague in India and in the United States in the early 1900s. It was so easy and frightening: the death of infected rodents led to the movement of hungry flea to people, which resulted in mass sickness due to the bite of the oriental rat flea.

The effects of the plague are a reminder that these small insects are in no way to be downplayed and why the oriental rat flea treatment is a major Health issue of concern to the population even today.

Preferred Hosts and Feeding Patterns

The Oriental Rat Flea prefers rodents as its major host when it comes to host preference. Their primary blood hosts are the black rat ( Rattus rattus ) and the brown rat ( Rattus norvegicus). But the fleas soon find other victims when rodents perish or their numbers are reduced. This is where people, cats and dogs usually turn out to be the victims by chance. Domestic infestations are normally through rodents that have brought fleas that infest in the storage areas, attics, or basements.

They are further resilient due to the behavior of Oriental Rat Fleas. It go through the four stages of their life cycle- egg, larva, pupa. And the adult- which is the blood feeding stage. They are capable of surviving weeks without food, until an appropriate host comes by. This is their ability that renders them hard to kill once they spread in an environment.

The fleas too are very flexible to warm humid climates and therefore they can breed better in urban areas, particularly when the sanitation is very low and the rodents are abundant. Their survival mechanisms and their capacity to cause changes in hosts are the reasons why plague and murine typhus outbreaks spread this fast in the past. Left uncontrolled even small infestation may become a significant health issue, which explains why it is essential to have an oriental rat flea treatment addressed promptly.
