Rats in Havering: How to Get Rid of Them and Stop Them Coming Back

Getting rid of rats in Havering comes down to two questions: how are they getting in, and what will stop the next ones? The answer looks different depending on which part of the borough you live in.

Rat Control Havering: £190 flat / £240 house

Two very different routes into Havering homes

Havering runs from a busy market town at its centre to open farmland at its eastern edge, and rats reach a house differently in each. Around Romford, older drainage under the streets near the station and the shopping parades is the usual route. Out towards Upminster and Rainham, a rat is just as likely to have come from a ditch, a field edge or an outbuilding as from a fault in the pipework.

Romford: when the drains are the route

The streets around Romford's town centre and station sit on drainage that has carried the area's shops, flats and older housing for a long time, and a cracked pipe or a shifted joint gives rats a way from the sewer into a floor void or a wall cavity. The giveaway is activity indoors with no obvious hole outside: scratching under the floor, a smell near the stairs, droppings behind a kickboard. A flat above one of the shopping parades can share this route with the business below it.

Harold Hill's shared roof lines

On the Harold Hill estate, long rows of near-identical postwar semis and terraces share party walls and roof lines, and a rat that gets into one house can move along that shared structure into the next. Checking whether a neighbour has the same problem is worth doing here before assuming the source is only your own home.

The Essex-border edge: fields, ditches and outbuildings

Towards Upminster and Rainham, Havering gives way to farmland, marshland and village-style streets close to the Essex boundary, and detached houses here often sit on larger plots with sheds, garages and outbuildings of their own. Rats can move in from a ditch or a field edge as easily as from a drain fault, so the search has to cover the garden as well as the house.

Getting rid of them: the order that works

  • Confirm the animal, and note where and when you see or hear it
  • Take away easy food: bird feeders, split bin bags, pet bowls left down overnight
  • Book treatment rather than laying poison where children, pets or wildlife could find it
  • Leave any holes you have found open for now, so no rat is sealed inside a wall
  • Once activity has stopped, close the route: proofing above ground, a repair below it

That last step is the one that decides whether rats come back, and it is also the easiest to forget once the house goes quiet.

Keeping them out once they have gone

Treatment removes the rats that are there; it does nothing to the gap they used. Above ground, that means sealing holes around pipes, worn thresholds and broken air brick covers with materials rats cannot chew. Where the route runs below ground, a drainage contractor can survey the pipe with a camera and repair the fault or fit a one-way rat blocker. Our rodent proofing service deals with the small, accessible gaps above ground.

Booking rat control in Havering
