(Rattus Norvegicus)

The Norway Rat is a common domestic, commercial and agricultural pest. Living in large communities, it is rare that where there is one rat there is not others. Capable of spreading numerous diseases, such as Weil’s Disease, Salmonellosis and Lyme Disease, it is essential that any suspected infestations are dealt with quickly, professionally and effectively to reduce risks to yourselves, your families and/or customers.



  • Body and tail combined length circa 200-270mm on average
  • Blunt nose with relatively small eyes and ears
  • Brownish fur, paler on the underside


  • Primarily a nocturnal animal though daytime sightings can be evidence of a large infestation
  • Large populations present throughout the sewer system
  • Lives mostly outdoors though will migrate inside if the environment allows

Life Cycle

  • Able to reproduce from 12-13 weeks old
  • Pregnancy lasts as little as 21days, able to conceive as soon as litter is born
  • Litters average 6-11 young, weaned after around 21 days

Frequently asked questions

Our Ambition is To “SOLVE” and avoid the traditional cycle of Bait – Stink – Flies – Repeat! Customers across Avon Somerset and Wiltshire are now enjoying the tranquillity of a rodent free home because we can check everything.

UNIQUE INSPECTIONS“. Drains, wall cavities, roof voids, cellars and rats in Kitchens are all considered in our unique inspection process. Everything we do is focused on solving your rat problem and not just treating it. Better still we do it all in house.

In the first instance ASW can carry out a rat treatment which will deal with the infestation and advice on any possible entry points if visible, if the rat infestation persists it is likely to be drain related and that’s where our Drainage side comes into its own.

You are dealing with the current infestation but because rats leave a pheromone trail others will always follow, the only permanent solution is to find the source of how they are entering your home via the drains and close the door once and for all.

We hear this all the time I’m afraid because the quality of drain inspection surveys with regard to rat activity is generally poor, simply surveying the main drains and reporting that they did not see any rats is not sufficient.

There are several no-dig solutions to resolve rat ingress within properties but sometimes the only solution is to excavate, a detailed drain inspection survey will give us all the information we need to be able to advice as to the best method of repair for your particular problem.

Recently we were informed by Wessex Water engineers that customers could get drain inspections carried out free of charge where the drains were easily accessible.

Wessex Water offers FREE drain surveys where you believe rats are entering your property from the drains.

Engineers are normally on site within seven days because rats are a potential fire risk so deserve to be investigated quickly. Wessex Water has a legal duty to check that drains (shared drains) under their jurisdiction are in good order and will repair any faults free of charge. Wessex water will also replace faulty or missing drain inspection chamber covers under their authority FREE.

Contact Wessex Water to find out how they could help you.

ASW installs Stainless Steel one way valves

This will not solve secondary issues such as the drainage system venting into your property via the defective drain and nor will they stop drain fly infestation via the same route.

We would always strongly recommend that the actual defect that allows rats to leave the drainage system and enter your property be located and fixed.
