The black rat is a mammal of the order of rodents. He is originally from India. Due to maritime traffic, it has spread throughout the world and is now proliferating as far as Quebec.
The black rat reproduces a lot and quickly. With a life expectancy of only one year, a rat has a potential offspring of 3000 individuals. This explains why it is quickly invasive; can destroy our crops, eventually cause fires and transmit diseases.

Black Rat Spread: What is their life cycle?
Black rats breed throughout the year. Gestation lasts 21 to 29 days. The litters range up to 5 per year, each range ranging from 6 to 16 pups.
At birth, black rats are hairless, blind and blood red.
They will be sexually mature within 3 months, in turn they reproduce.
The average lifespan of a black rat is about one year, when it is in the wild. Living conditions are difficult for rodents in the wild, due to the many predators.
Protected from predators (nest in a barn or basement) in some cases, especially when it infests our homes, the black rat can live up to 3 or 4 years.
How is an infestation of black rats harmful?
The black rat climbs and nests in high places. It can be found in trees and on the upper floors of buildings, attics, under toits, etc.
Black rats feed mainly on plant products. When they are in the wild, they feed on dried fruits, seeds and buds. Sometimes they feed on small invertebrates such as arthropods, myriapods, gasteropods, etc.
An adult rat consumes 15 grams of food and drinks 15 ml of water per day.
Black rats pick up everything in their path. In the wild, they damage fruit trees and crops, whether they eat them or not.
In the house, they nibble on the reserves. They urinate and defecate on the leftovers of their meals, thus spoiling the food by making it unconsumable.
Vector of serious diseases
The black rat is the rodent that has the most widespread bubonic plague in the world. The disease claimed the lives of millions of people in the Middle Ages.
It remains a vector for many deadly diseases such as leptospirosis.
In addition, black rats eat insulation, electrical cables,causing financial loss and fire risk.
