Confirm the problem, remove what is feeding it, deal with the active rats, then close the way in. In that order — and here is why the order matters.
Getting rid of rats properly means doing four things in sequence: confirm what you are dealing with, remove the food and harbourage supporting it, treat the active problem, and close off the way in.
Professional treatment is £190 for a flat and £240 for a house. Proofing, which is the fourth step, is a separate £180 service. Skipping straight to step four is the single most common mistake.
This sounds obvious and it is skipped constantly. Mice, squirrels and even birds in a roof space all produce noises and evidence that people reasonably attribute to rats, and the right response is different for each.
Rat droppings are noticeably larger than mouse droppings — roughly the size of a large grain of rice or bigger, against the small dark specks mice leave. Rats also tend to produce more obvious gnawing damage, and noises from rats are usually heavier and lower down in the building than the fast, light scuttling of mice in a loft.
If the noise is coming from directly above a bedroom ceiling in broad daylight, a squirrel is worth considering too.

None of this removes an established rat problem by itself. All of it makes the property less worth returning to.
This is the step where professional treatment earns its money, and where DIY most often goes wrong.
Our published prices mean you can weigh that against a fortnight of shop-bought traps before you commit to either.
Amateur rodenticides are deliberately weaker than professional products, and rats are neophobic — genuinely wary of new objects in a familiar environment. A trap placed in the open, in the wrong spot, handled without care and given up on after three days is a common and entirely understandable failure.
There is also a real risk side. Poison placed carelessly is a hazard to pets, children and wildlife, and a rat that dies inside a wall cavity or under a floor creates a smell problem that lasts weeks and cannot easily be reached.

View Rat Control Harrow Weald →Once the active problem is dealt with, the question becomes how they got in — because if nothing changes, the same route stays available to the next rat that comes along.
Rats can pass through surprisingly small gaps and will gnaw a small opening into a larger one. Common routes include gaps around incoming pipework and cabling, damaged air bricks, worn gaps under doors, and defective drains.
Our proofing service is £180 and covers up to one hour of work on suitable small holes. Where the underlying cause is structural — a collapsed drain, a hole that needs bricklaying — that is building work, and we will tell you that rather than papering over it.
Read nextRat Proofing Harrow Weald – How Much Does It Cost? →Doing step four before step three is the classic error. Sealing a building that still has rats inside it does not get rid of them — it traps them in, and the damage they do trying to get out is frequently worse than what they were doing before.
Treat first, then proof. A sealed building with rats still inside it is a worse problem than the one you started with.
There is no prize for persistence here. It is worth getting professional treatment when:
Professional rat treatment is available throughout Harrow Weald HA3 for houses, flats, landlords and businesses. Properties with gardens, garages and outbuildings often need the outside of the building considered as carefully as the inside, since that is usually where the route in begins.
It depends on how established the problem is and how much of step two you have done. It is not usually an overnight job, and anyone promising you that it is should be treated with suspicion.
If the food source and the access route are both still there, something will eventually use them again. That is exactly what step four is for.
Not generally, but ask us about your specific circumstances — particularly if there are pets or small children in the house, because that genuinely affects how and where things are placed.

Deal with the active problem, remove the food and shelter supporting it, then close off the access route. Leaving any of the three undone is what causes a repeat.
£190 for a flat and £240 for a house.
Amateur products are weaker than professional ones, and rats are wary of unfamiliar objects. They work sometimes, often slowly, and carry real risks to pets and wildlife if placed carelessly.
No. Proof after the active problem has been dealt with, not before — sealing rats inside a building makes things worse.
Their use by non-professionals is restricted in England. We do not recommend them in any case.
There is no reliable evidence that either resolves an established rat problem.
