Harrow's housing stock shapes the pest problems you'll meet here. Rows of 1930s semis in Pinner, Hatch End and Rayners Lane come with airbricks, loft voids and old drainage runs that mice and rats exploit. Flats above the shops on Station Road and in Wealdstone see a steady run of cockroaches, bed bugs and pigeon issues. Gardens backing onto the Grimsdyke, Harrow Weald Common and the railway embankments along the Metropolitan and Chiltern lines make rat sightings a regular call-out. Wasp nests peak in late summer, often in loft eaves or garden sheds, and most pest firms here can reach you within a day or two.
The businesses on this page were drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those showing a working website and phone number. We read each business's homepage to confirm pest control is what they primarily offer, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page has the full list. For anyone without that badge, we haven't independently verified those things, so you'll want to check them yourself before booking.
Start by asking what's included. A good quote states the pest, the number of visits, the treatment method and whether a follow-up is covered. Ask for proof of public liability insurance, and ask which relevant trade accreditation they hold. Anyone using rodenticides should be able to explain how they store and dispose of them safely, especially if you have pets or children. Get two or three quotes, because prices for the same job can differ by £50 or more. Be wary of anyone who won't give a price range over the phone or who pushes a large upfront package without inspecting the property first.

Prices vary with the pest and the severity. Expect roughly £60 to £120 for a single wasp nest treatment, £100 to £250 for mice, and £150 to £350 for rats, often with two or three visits. Bed bug treatment is dearer, usually £250 to £600 for a flat and more for a larger house. Cockroaches and fleas typically fall between £100 and £300. Rodent proofing, such as sealing gaps and fitting airbrick covers, is usually extra. Getting two or three quotes is normal and worth the time.
How quickly can a pest controller visit?
For wasps, rats and anything affecting a kitchen or food business, many firms can attend the same day or the next. Less urgent jobs like ants or moths may wait several days. Ring first thing in the morning and say clearly what you've seen, where, and for how long. That helps the firm judge urgency and bring the right equipment on the first visit.
Will the treatment be safe for my pets and children?
Ask before the visit. Rodent bait is normally placed in tamper-resistant boxes, but you should still keep dogs and cats away from them and from any treated areas. Insecticide sprays for bed bugs or cockroaches usually need you to stay out of the room for a few hours. A reputable firm will explain the products used, where they go and how long you need to wait. If they can't answer clearly, look elsewhere.
Should I do anything before the pest controller arrives?
Yes. For rodents, tidy away food, clear clutter near walls and note where you've heard scratching or found droppings. For bed bugs, wash bedding on a hot cycle and bag it, and don't move furniture to other rooms as that spreads the problem. For wasps, keep everyone clear of the nest and don't try to knock it down. Taking a photo of the pest or damage helps the technician prepare.
Does a one-off treatment fix the problem for good?
Not always. Killing the pests deals with today's infestation, but if the entry points stay open they'll be back. In Harrow's older semis, gaps around pipework, loose airbricks and damaged soil pipes are common culprits. Ask whether the quote includes proofing work or a follow-up visit, and whether any guarantee covers a return. A written guarantee should state its length and what it excludes.
How do I choose between pest controllers in Harrow?
Check these before you book. Ask for proof of public liability insurance and a copy of the certificate. Ask which relevant trade accreditation they hold and how long they've been trading. Read recent online reviews and look for comments on the specific pest you have. Get a written quote that names the pest, the number of visits and any guarantee. Be cautious of cold callers or anyone who quotes a high fixed price without seeing the problem. Businesses without a Trust Verified badge haven't been independently checked by us, so these steps are down to you.
