Sewer rats are not from North America. Their proper name is the Norway rat and they came here on ships in the 17 and18 hundreds. In North America, they have no real predators so their population exploded and the sewer rat became one of the biggest threats to civil life in the world. The issue was eventually quelled when governments began treating the rat issue on mass instead of relying on the individual to treat their own issue only for the rats to move on to the next house down the street to start the invasion all over again.
To deal with the rats in your drain pipes or coming through your toilets is to exclude or seal off any drain opening. Make sure every tap has mesh and the drains on the floor of the basement are covered and fitted to the floor with bolts. Do not take any chances with sewer rats, they are a severe and dangerous infestation and they can essentially they can come from anywhere.
Now, back before the 2008 economic meltdown, the major cities of North America would treat all sewers for rats using rat bait. However when the recession hit the governments of America decided to cut a lot of costs that dramatically reduced the quality of life for those of us who are not millionaires. With the halting of the sewer rat treatments, the population has exploded and rats have invaded the city en masse. With Covid and everything else going on the world has lost all preparedness and the cost has come down to the individual. This has been a long road to this point, with failures on the government’s part showing great disregard for the safety and health of its population while people protest mask-wearing and life-saving vaccinations for their children. This has all accumulated into a pest invasion that is costing the people of the city billions in lost food, damage, and emotional tolls.
If you have a serious rat issue in your home then you can be sure the rats are outside in the yard as well. They enjoy burrowing into the ground, under sheds and decks, and under foliage and shrubbery. They are very good at hiding and are difficult to find outside until they manage to get into the house. That is usually when most people realize what is happening and call a professional to come and resolve the issue.
Do not try to resolve and complex rat issue on your own as you are not a trained technician and your actions could very well make the infestation worse, or make the treatment less effective. So make sure to call a professional to come to your home and bait the exterior, exclude and seal entry points and then lay baited snap traps in your home to catch the rats and prevent them from dying in the walls which can cause severe health issues as well as a god awful smell.
