Rats often use sewer pipes to gain access to properties. They will even build their nests in pipes if there is enough room. If rats decide to nest in your sewer pipes, then not only do you have to deal with the rats, but you also have to take care of the blockage their nests create.
Accessing the pipework rats use is often a difficult and cumbersome task and might even require a professional plumber. If you suspect you have rats in your sewer pipes, you need to deal with them as quickly as possible.
The first thing to do is prevent more rats from gaining entry. Installing rat blockers over the ends of pipes ensures rats and other rodents can’t get in. You should also check your property for any broken drains or pipes; rats can squeeze through the smallest of gaps, so fix any damage you find, even if it seems insignificant.
As far as killing or catching the rats goes, you will usually need a professional pest controller to take care of them for you. It might seem like an obvious solution would be to pour some kind of poison down your pipes to kill the rats, but that will just create new problems.
The only thing worse than having rats living in your pipes is having dead rats rotting in your pipes. The smell of a decaying rat is very unpleasant and can permeate your entire home. Professional pest controllers can also perform follow-up checks to ensure the infestation has been dealt with for good.
If rats have built their nests within your pipework, you might need a drainage expert to take a look and unclog it if necessary.
You can prevent future occurrences by keeping your garden tidy and well-maintained and checking your pipes periodically for signs of damage or wear and tear.
