Rats living in your home’s drainage system might sound like yet another urban myth about these rodents, but it’s actually a surprisingly common problem. Rats frequently enter properties via drainage systems; drain pipes provide them easy and convenient access to roofs, while their flexible, malleable bodies enable them to squeeze around u-bends and use a toilet to gain access to a property. Whereas mice can live off minimal amounts of food and water, rats need to feed every day and take on water. Drainage systems can provide them with all the water they need and make ideal nesting locations from which rats can head out and scavenge for any food they need.
If you discover rats in your drainage system, removing them should be a top priority. There are preventative measures you can take to prevent them from gaining access in the first place, and these can help prevent more rats from finding their way in and adding to the problem once they’re already in there.
Your first instinct might be to kill the rats in your drainage system using poisonous liquids, but this will only cause more problems. For one thing, you’ll have dead rats clogging your drains that will be difficult to remove. As the dead rats decay, they will release a foul odour that will find its way into your property.
A better solution is to install rat stops on any entrances to your drains that rats might use and then use some combination of poisons and traps to deal with the rats when they emerge from their hiding place. If you want to remove the rats from your drainage system as quickly and efficiently as possible, you should call in a professional pest control contractor to deal with them for you. You might also need a plumber if they or their nests have blocked your pipes.
