If you walk into your bathroom and discover that your toilet seat looks like it has been aggressively gnawed away from the underside (just like in the photo above), we have some bad news. You don’t just have a minor mouse issue—you likely have a rat coming straight up through your drainage system.

As startling (and terrifying) as it is to look at, this is a classic signature of sewer rats. But before panic sets in about your plumbing and your anatomy, local homeowners across Exeter, Exmouth, and East Devon need to know why this happens and how fast you need to act.

Why Do Rats Target the Toilet?

It sounds like something straight out of a horror movie, but it is a very common reality for UK homes:

• The Sewer Highway: Brown rats are incredible swimmers and can hold their breath for minutes at a time. They navigate local Exeter sewer systems and can squeeze through tight bends in drainage pipes, popping straight up into your toilet bowl.

• The Need to Chew: A rat’s teeth never stop growing. To keep them trimmed, they have to constantly gnaw on hard surfaces—plastic, wood, and composite bathroom fixtures are prime targets.

• The Search for an Exit: Once a rat makes it up into the U-bend, it will explore the rim of the toilet seat trying to find a way out into the wider house, resulting in that distinctively chewed, splintered plastic you see above.
