If rats keep coming back however many times they are treated, the drains may be the route in. A rat gate could be the answer.
Many homeowners are surprised to learn that rats inside the house often come from the sewer rather than the garden. Rats are strong swimmers and good climbers, and they can use damaged or disused drain pipes to reach wall cavities, floor voids and even bathrooms.
What is a rat gate?
A rat gate, sometimes called a rat blocker or non-return valve, is a device fitted inside the drain, usually in the inspection chamber (manhole) nearest your property. It contains a hinged flap. Waste water pushes the flap open as it flows away, but the flap closes behind it, so rats cannot travel back up the pipe.
Signs your rat problem may be coming from the drains
- Rat activity keeps returning after treatment
- There is no obvious entry point from outside
- Activity is concentrated near soil pipes, bathrooms or kitchens
- Rats have been seen in or around a manhole
Is a rat gate always the right solution?
Not always. The drain needs to be inspected first to check its condition, size and layout. If a pipe is broken, it may need repairing as well. A drain camera survey can help find the exact problem. Where drains are shared with neighbours, the water company may be responsible for some sections.
How we can help
We inspect the drain, confirm whether a rat gate is suitable and install it where appropriate, alongside any treatment needed to deal with rats already inside the property.
