The south of Friern Barnet ends at the North Circular and the Friern Bridge retail park, and that edge shapes where its rats turn up. Service yards, large commercial bins and the planted strips beside the road give rats food and cover within reach of the nearest back gardens.
Treating rats costs £190 in a flat and £240 in a house anywhere in N11. Book a rat visit online or ring 0800 955 2347.

A retail park produces a steady flow of food waste and packaging, and the bins behind the units are emptied on a timetable rather than the moment they fill. The verges and planting beside a major road give cover that nobody disturbs. Neither is a problem on its own, but together they give rats a base with food close by, and the houses and gardens nearest that edge are the next stop when they forage further or their numbers grow.

A rat foraging out from roadside cover does not stop at a fence. Gardens with a compost heap, a bird table, fruit trees or a dry space under a shed offer the next meal and somewhere to dig. Once a burrow is established in your garden, the rats in it are yours to deal with, wherever they first came from. The guide on rats in the garden explains when a sighting outside means more than an animal passing through.
Further north, the apartments on the former hospital site and in the newer housing around it share bin stores, and a store with split bags or a door wedged open draws rats in from the grounds. Rats in a communal area are for the managing agent to arrange; rats inside your own apartment are what you book for. Can rats get into flats and apartments? covers how they reach the floors above.
The first signs of rats sets out what droppings, smears and noise tell you. Much smaller droppings indoors may point to mice rather than rats.
When you book rat control, tell us whether you are in a house, a flat or an apartment in a converted building, and where the activity is: the end of the garden, a garage, the bin store, under the floor or in the loft. Say whether the garden backs towards the road or the retail park, because it helps show where the rats may be coming from.
Give clear access to the garden, the garage and the space under the kitchen sink, and keep pets indoors. Before leaving, the technician will talk you through what the garden and house showed and what comes next. How long it takes depends on the property and how settled the rats are, and how long rat control takes explains what affects it. Get back in touch if new burrows or fresh droppings appear.

You cannot change what lies beyond the back fence, so the work happens on your side of it. Keep the ground under sheds and decking open or meshed, stand compost bins on a wire base, and keep the far end of the garden clear so there is nowhere sheltered to dig. Gaps into the house, such as a broken air brick or a hole where a pipe goes through the wall, can be closed with rodent proofing in Friern Barnet, and rat proofing goes into the detail. If activity keeps returning, why rats come back after treatment is worth reading.
For the wider picture, including the brook corridors that matter more in Whetstone, see Rat Control Barnet.
Once the rats have gone, the cracked air brick or loose pipe entry they used is still open, and rodent proofing seals small gaps like that for £180 for up to one hour.
For rats in Friern Barnet you pay £190 if you live in a flat and £240 if you live in a house. An apartment in a converted building or the newer housing is charged as a flat, and a house on Friern Barnet Lane, Colney Hatch Lane or the roads near the North Circular as a house. The price is for dealing with the rats at your home, and closing their way in is booked separately.
| Treatment | Price |
|---|---|
| Rat Control – Flat | £190 |
| Rat Control – House | £240 |
It may be part of it, since roadside cover gives rats somewhere to live close to gardens. What keeps them in your garden is food and shelter on your side of the fence, so start there, and a visit deals with the rats already settled.
Businesses are responsible for pests on their own sites. A booking for your home covers your property only, so it is worth tackling your own garden whatever is happening beyond it.
Report it to the managing agent, who normally arranges treatment of communal areas. If there are signs inside your own apartment as well, you can book that yourself at the flat price of £190.
They can climb inside wall cavities, ducts and boxed-in pipes, so the upper floors are not out of reach, although ground floors are more usual. Where rats nest in houses and flats explains where they settle once inside.
Both are possible where tall trees stand close to houses. Squirrels are loudest around dawn and dusk, rats mostly at night. Rats in the loft and squirrel control in Friern Barnet cover the two.
It helps where several gardens along the same stretch have activity, because rats move between them. Each booking covers the property it is made for.
