Residents in Sutton have raised £3,000 of their own money to clear a fly-tip that had been attracting rats for six years, after what they describe as a long and frustrating battle to get the site dealt with.
The Sutton Guardian reported that the dumped waste, which included asbestos, had become a persistent source of rodent activity in the area.
At London Pest Control Co., we find coverage like this properly frustrating to read. Fly-tipping feeds rat infestations directly, and the longer a dumped waste site goes untouched, the worse the rodent situation gets for every property nearby.
Why fly-tips feed rat populations
Brown rats are not fussy eaters, and household waste nearly always contains enough food residue to sustain a breeding population, even when the dumped material looks like builders’ rubble or old furniture.
An undisturbed heap of materials also gives rats shelter from predators and weather, and they will nest right inside a fly-tip if it stays put long enough
Six years is a long time for a site like that to remain in place.
In our professional judgement, a rat population with that kind of undisturbed access to food and harbourage will have established nests well beyond the tip itself.
A single pair of brown rats can produce five or more litters a year, with each litter averaging around seven pups that reach sexual maturity within a few weeks.
Over six years, even a modest initial population can spread across a wide area, particularly in suburban settings where gardens, sheds, and older housing stock provide plenty of secondary nesting opportunities.
Asbestos in the waste adds another layer of difficulty. Disturbing asbestos-containing materials without specialist handling creates a genuine health risk, and it may well have been one of the reasons the site sat untouched for so long.
Rats do not care about asbestos, though. They will gnaw through and around it, and their burrowing can disturb materials that would otherwise have stayed sealed.
Where the rats go after clearance
Clearing the fly-tip was the right thing to do, and the residents who fundraised for it deserve real credit. But removing waste does not remove an established rat population.
Rats that have been living and breeding around a site for years will have burrows and runs that extend well beyond the visible waste. Once the tip is gone, those rats do not simply disappear.
They move outward, looking for the next available food source and shelter, which usually means neighbouring gardens, outbuildings, and the gaps around utility entries on nearby houses
We see this pattern regularly across south London. A food source gets removed or a building gets demolished, and within weeks the surrounding streets notice a sudden increase in rat sightings.
The rats were always there, but the loss of their primary site pushes them into areas where people actually notice them.
A proper response after clearing a site like this would involve a professional survey of the surrounding area, followed by a targeted baiting programme and proofing work on any properties showing signs of rodent entry.
Proofing means physically blocking the gaps that rats use to get inside, which for a brown rat can be any hole wider than about 25mm.
We carry out that kind of work right across Greater London, including Sutton and the surrounding boroughs, and it always starts with a survey rather than jumping straight to treatment.
Laying bait without understanding where the rats are nesting and how they are moving through an area is a waste of time and money.
The wider problem for Sutton and south London
Fly-tipping has been getting worse across London for years, and the boroughs in south London are among the hardest hit.
Every dumped mattress, bag of rubble, or pile of food waste left on a verge or in an alleyway is a potential food and harbourage source for rats
Local authorities are under real pressure, and clearance can take weeks or months depending on the type of waste and the resources available. During that time, rat populations grow.
A site that starts as a minor nuisance quickly turns into a serious infestation problem for an entire street.
By the time the waste is finally removed, the rats are well established in places that have nothing to do with the original tip.
Residents and landlords in areas with persistent fly-tipping should not wait for the waste to be cleared before thinking about rodent control.
If you are seeing rats in your garden, hearing scratching or movement under decking or in cavity walls, or finding droppings around bin stores, those are signs of an active population that needs professional attention now.
Our technicians work across all 32 London boroughs and the Home Counties, and we offer same-day callouts for rodent problems.
We are BPCA-accredited and Think Wildlife accredited, which means any rodenticide we use is applied responsibly and in line with current stewardship requirements.
If you are dealing with rat activity in Sutton or anywhere else in Greater London, call London Pest Control Co. on 020 7046 0255 or request a free survey through our website.
We are available 24 hours a day, seven days a week, and we would rather get to a problem early than deal with a population that has had six years to dig in.
