Natural Diasters: Hurricanes, Fires, Earthquakes and Rats!

by | Sep 26, 2017 | 3 comments

roof-rat-on-lightMembers of the Muridae family are the dominant species in every region of the world, due to their ability to adapt to and exploit new situations. Commensal rats and mice, those that live at the expense of humans, invade their dwellings, eat their food, upset their comfort, and frequently transmit diseases to them, belong to this family. Three species of commensal rodents are the most widely distributed: the Norway Rat, Rattus norvegicus; the Roof rat, Rattus rattus; and the Common (House)  mouse, Mus musculus.

When natural disasters strike, rats and mice experience the same suffering as humans. Many of them are crushed to death or drowned, die of starvation, or fall prey to infections. Their populations are frequently decimated. Survivors, fearful and disorganized, wander into new areas in search of protection, shelter, and food. It taRat yellingkes time for them to regroup and reorganize their social behavior, become familiar with their new environment, find safe havens, locate food and water, and memorize their movements. All this occurs before they can again begin reproducing.

Colony building and reproduction will only begin when their new ecosystem has stabilized. This typically takes 6 to 10 months under favorable conditions. As the rodent population grows and resettles, people have a greater chance of being exposed to the diseases carried by rodents. Rodent urine and dander also contain allergens that can cause allergic reactions or trigger asthma symptoms in sensitive persons and more than 9,000 persons are treated in emergency departments annually for rat or mouse bites

Young babies, bed-confined elders, and the homeless sleeping in doorways and alleys, however, are occasionally bitten by unprovoked rats.  In some cases, those cleaning up debris after natural disasters will come in contact with frightened rats (mice) and may experience bites. 

So even with immediately decreasing populations, rats are perceived to be increasing because they gravitate to the same areas as humans and become more prevalent and  evident in those environs.

Why are rodent populations, and their movements, so important after disastediaster-damagers? Because events like Hurricane Irma and Jose, the fires in our great northwest, tornados in the midwest and the earthquakes in the U.S. and Mexico, can change the ecology of affected areas, making it more favorable to rats and other vermin. At the same time, they can curtail community services that can keep these  pests in check.
