Rats are incredibly prolific creatures and can have litters of anywhere between two and twelve baby rats. The average litter size is six. This means that over the course of their relatively short lives a female rat can easily produce over fifty offspring.
Rats are able to become pregnant again almost immediately after giving birth which contributes to their high reproductive potential. They can have up to seven litters per year although the average is three or four.
Given the large number of babies that rats can have it’s not surprising that their population can grow very quickly. If not kept in check a small number of rats can quickly turn into a large infestation.
Fortunately rats are not particularly difficult to control and there are a number of effective methods for doing so. If you think you may have a rat problem the best course of action is to contact a professional pest control company who will be able to advise you on the best course of action.
