Rodents

Last reviewed:

Rodents at your property can be particularly unpleasant and we are aware that our sewers can provide the perfect habitat for them to live and move about.

If a rodent infestation is present in sewers affecting your property we will work in conjunction with the local authorities and the Environment Agency to resolve the issue.

If you have confirmation of a sewer infestation you can report this to our Customer Services team.

What can cause rodents?

Sewers are ideal habitats for rats to either nest or use as a network to get around.

An abundance of food, for example, if food premises are draining into sewers can encourage rodents and if there are defects in the sewer this can lead to rodents moving between above and below ground and vice versa.

The less urban areas become the less likelihood rodents will nest in sewers.

It’s important to note rodents can be a recurring issue as:

  • Population recovery of rats is high; therefore, depending on the success of baiting, it is possible for populations to recover within 6 months
  • Rats can burrow and gnaw through most materials; damaging sewer lines and causing and worsening defects
  • Rats will move readily from surface to sewer and vice versa; a co-ordinated approach with Local Authorities is therefore essential
  • Rats move easily through the network and between manholes; new rat colonies can quickly move in

What to do

First contact your Local Authority who are able to arrange an investigation that can identify where the rodents are coming from.

If rodents are confirmed coming from our sewers, you can report this to our Customer Services helpline 0800 316 9800.

If the rodents are identified as coming from above ground, you will need to work with your local authority, who can help you to organise appropriate baiting.

What we can do for you

We will work with our field engineers to carry out the most appropriate resolution either through laying bait or fixing any defects in our sewers

Please note that we are only authorised to lay bait in our sewers. Local authorities are responsible for laying bait above ground.
