Rat Control — Duxford

Why Do Rats Keep Returning to the Same Duxford Property?

If rats return to the same property after treatment, the drains are the first place to look. Not the second, and not after another round of baiting.

This is the single most useful thing to know about recurring rat problems, and it is the reason some properties seem to need treating over and over while the house next door never does.

Where Brown Rats Actually Live

Brown rats live in and travel through the sewer system. That network runs directly underneath and into every property, and it is warm, sheltered and full of food. Where the drainage is sound, they stay in it. Where it is not, they come up inside the building — and they keep coming up, because the route is permanent.

What a Defect Looks Like

  • A cracked or collapsed section of pipe
  • A displaced or open joint
  • A redundant branch capped off badly, or not at all, during building work
  • A missing or broken rodding eye cover
  • A defective or missing gully
  • An old toilet connection left open under a floor after a bathroom was moved
  • An unsealed penetration where a soil pipe passes through a wall or a slab

None of those is visible from inside the house. None of them is affected by a treatment. And every one of them is a permanent open door.

The pattern that gives it away. A property clears completely after treatment, stays clear for weeks or months, then has rats again — and does it repeatedly, regardless of who treated it or what they used. That is not a treatment failure. That is a route nobody has looked for.

Other Clues

  • Activity that appears at ground floor level with no evidence of anything entering from outside
  • A property with recent building work, an extension or a moved bathroom or kitchen
  • Older drainage, or a property where the drainage layout is not known
  • Rats in a downstairs toilet or a ground floor bathroom, which is as direct a clue as this gets
  • Neighbouring properties unaffected, which argues against a general local problem and for something specific to your building

Where That Leaves Us Being Straight With You

If the evidence points at the drainage, we will tell you, and the fix is a drainage repair rather than another visit from us. Selling a third round of baiting for a problem with an open pipe underneath it would be taking your money for nothing.

What We Can Do

  • Identify it — the pattern of activity, where it appears and how it recurs is usually enough to point at drainage
  • Deal with the rats that are in the building now
  • Proof the structural routes, priced separately by time
  • Tell you plainly what to get a drainage contractor to look at, so you are not paying us to treat around a problem we cannot fix

A drainage survey with a camera is the usual next step, and it is a specialist job. Where it finds a defect, repairing it is frequently the end of a problem that had been going on for years.

Common Questions

Why do rats keep coming back after treatment?
The commonest reason is an open route in the drainage. Treatment deals with the animals present; it does nothing about a defect that lets new ones up.
How would I know if it is the drains?
The pattern usually gives it away: the property clears completely, stays clear for a while and then has rats again, repeatedly, regardless of who treated it. Activity at ground floor level with no sign of entry from outside points the same way.
Can you repair the drain?
No — that is drainage work rather than pest control. We will tell you what the evidence points at so you can get the right trade in.
Is it common after building work?
A redundant branch capped off badly, or an old toilet connection left open under a floor, are among the most common defects we see behind a recurring problem.
