How do sewer rats get in your house?

So how do sewer rats get in your house? Sewer rats are a near-universal problem for urban populations; where you have sewers, you have sewer rats. Sewers provide rats with the food and shelter they need to thrive. Sewer systems remain warmer than the ground above when the temperature drops and stay cool when it rises. There are also no humans and very few other animals to contend with.

Not only does this ensure the rats’ safety, but it also means they can take all the available food for themselves. Obviously, there’s plenty of water in the sewers, which rats need to survive. Rats can also use water to travel, thanks to their excellent swimming abilities.

Unfortunately, rats don’t tend to stay in the sewers once they’ve made a nest. With no people or other predators around to control the population, sewer rats will continue to multiply until the local environment can no longer support them. Once this critical tipping point is reached, some of the rats will be forced to venture outside the sewer for their food, water, and shelter. Flash floods, maintenance work, and construction projects all also have the potential to displace sewer rat populations and send them into homes and garages to scavenge.

After reaching the surface, sewer rats have no difficulty finding their way into people’s homes. All they need is a small crack in the property’s brickwork or foundations. Rats can also crawl up drain pipes and enter homes through floor drains, roof drains, and even toilet bowls.

You can deter surfacing sewer rats from entering your property by installing protective covers over your drains and pipes. These covers allow water to flow freely but won’t let anything as large as a rat, or even a mouse, get through. Sewer rats are more likely to surface following heavy rain or during construction and maintenance works.
