Homeowners whose gardens are invaded by rats from a neighbour's property have legal options, including reporting the infestation to their local council's environmental health department if it poses a public health risk or statutory nuisance under the Environmental Protection Act 1990.
Rat activity in the UK peaks between September and November, as the breeding season ends and rats seek food and shelter in homes during the autumn chill. While natural deterrents can help, infestations can seem inevitable when rats first enter a neighbour's garden.
Homeowner's chicken coop concern
One homeowner took to Reddit after repeatedly finding rats entering their garden from their neighbour's side, believing the neighbour's chicken coop had attracted them. "During the day, I spotted two rats in my garden, seemingly sniffing around some of the flower beds," they wrote. "I went outside to see where they may be coming from (one of them was brazen and didn't disappear immediately when I went outside) and spotted two little tunnels dug under the neighbour's fence through which they must have came through."
They added: "My neighbours started keeping chickens in a chicken coop recently, and I can only assume the rats found some feed. In the five years we have lived in this house, we have never had any issues with rats or seen signs of them." The homeowner asked whether to talk to the neighbour despite a strained relationship, or simply call pest control.
Legal framework for rat infestations
Section 79 of the Environmental Protection Act 1990 states that premises in a state prejudicial to health or a nuisance—such as from accumulated rubbish or poor waste management—allow councils to serve an abatement notice. The Prevention of Damage by Pests Act 1949 requires landowners and occupiers to keep their property free from rats and mice, giving local councils the power to take enforcement action.
As a homeowner, you are legally responsible for ensuring your own property does not attract or harbour pests, meaning you should avoid placing traps or poisons directly over boundary lines.
Recommended steps for homeowners
One of the first recommended steps is to talk to the neighbour, as they might not be aware of the issue. Inspect your garden for holes or possible entry points, and block them. Secure your bins, clean up garden clutter, and stop feeding wildlife if it draws rodents closer.
If the neighbour refuses to act and the infestation affects your health or environment, reach out to your local authority's environmental health team with documented evidence.
