What are a rat's mating habits?
As in every living creature, there are usually multiple species. This is no different with rats, but we will discuss the mating habits of the Black Rat, also known as the Roof Rat, and its cousin, the Norway Rat, also known as the Brown Rat.
As the name suggests, the Black Rat / Roof Rat prefers to live high-up, such as in attics, buildings, and rafters while the Norway Rat / Brown Rat, prefers low-lying areas such as the sewers in subways, on the ground floor of buildings and burrows under buildings. The Black Rat / Roof Rat can either be black, grey, or brown, while the Norway Rat / Brown Rat is brown or grey but not black. The Black Rat / Roof Rat is good at climbing, very agile in fact, but it does not like to swim. The Norway Rat / Brown Rat is good at swimming, but not very good at climbing.
The rat population is so large, basically because rats multiply at significantly faster rates. The mating habits of both rats are almost the same, with only minute differences. All rats mate with multiple partners, females being able to switch partners even during a 'session' and the male rat being able to ejaculate several times in a row, ensuring that they passed his gene on. Once conditions are satisfactory, rats mate throughout the year, but the Norway Rats favor Summer and Autumn more.
Since rats live in large groups, there is usually a more dominant male and 2 or 3 more dominant females, creating more of a linear male hierarchy. The more dominant male is usually the most successful breeder, mating with as many female rats as he wants. Females are considered more aggressive than males and sometimes, rats defend both their mates and their territories through aggressive behavior.
Another difference between the Norway Rats over other species is that the females prefer male partners who have not mated before or who did not suffer from or experience stress during their early years. A female rat can mate as much as 500 times per a 6-hour period, with different partners. Female rats usually experience this up to 15 times a year which is how a single female rat can produce up to 2,000 babies per year. Gestation for the Black Rat is 4 weeks, and for the Norway Rat, approximately 3 weeks. This means that the Norway Rat can be pregnant twice within one month, but it is very unhealthy to be both pregnant and weaning.
Each female rat can produce a litter of 6 to 12 babies, all born blind, deaf, and hairless. They would take approximately 3 to 4 weeks to stop nursing and then, one week after, the vicious reproductive cycle can start all over again, with a new breed of rats. Luckily, the average survival rate of rats is between 2 two and 3 years. Abortion is also common among female rats if there is inadequate food, nesting materials, overcrowding, or too much noise.
RAT RISKS AND TRAPPING: Rats chew on electrical wires, which can cause outages or even worse risk of fire in your home or building. They also chew on other surfaces, such as water pipes, which can cause leaks, piping insulation, wood, plumbing stacks, and more. They burrow in insulation and have nests of baby rats. It can pose a health risk if they leave urine and feces everywhere. We trap and remove 100% of the rats in your house, using our innovative process, the best in the world.
ATTIC CLEANUP AND DECON: We offer attic cleanup, odor control, and decontamination services. This process ensures we eliminate the health risk associated with rodent droppings and urine, along with the odor problem. Rats leave behind pheromones that can attract new rats, and predators such as raccoons or rat snakes, to enter the attic. We offer cleanup, including fogging, to full insulation replacement services where applicable.
HUMANE SOLUTIONS: Our process does not rely on the usage of poisons. Poisons are a lazy and ineffective approach, which never permanently solves the problem. The main thing poisons cause is the stink of dead rats in your attic and walls! New rats keep coming. Our process relies on sealing shut all entry holes so that no rodents can ever enter the structure again. We can cage trapping or exclusion, though snap traps are actually the most humane approach.
