Homeowners are being warned about a surge in rat activity, with recent figures showing a 10% increase nationwide. Searches for ‘rats in my garden’ have jumped by 575% on Google, highlighting growing concern as more people spot these unwelcome visitors in their backyards.
Robin Antill, founder of 1st Choice Leisure Buildings, explained how to spot the early signs of an infestation and prevent rats from taking up residence. He says droppings are one of the most obvious indicators.
Small, dark brown pellets roughly the size of a raisin can often be found around sheds, decking and fences. Holes or burrows along these areas are also common, while dirty or oily smears along walls and fences are caused by rats repeatedly rubbing their fur on the same routes.

Rats may also leave a strong ammonia smell in enclosed spaces such as sheds, as they mark their territory with urine. Rustling or scratching noises at night, flattened grass and flowers and gnaw marks on garden furniture, fences and decking are further signs that rodents are present.
These pests prefer dark, secluded areas that provide access to food and water. Decking, sheds and summerhouses are particularly attractive because they are dry, sheltered and less likely to be disturbed.
Rats often burrow both underneath and inside these structures, finding warmth and sometimes even easy access to pet food. Compost heaps and overgrown areas are also popular, especially in winter when the internal heat from decomposing matter offers a cosy refuge.

Certain garden features can inadvertently encourage rats. Bird feeders, for example, provide a constant supply of food as seeds fall to the ground. Fallen fruit from trees offers another easy meal, while poorly secured compost heaps give rodents both shelter and warmth, explained Antill.
Preventing infestations requires taking several practical steps:
Homeowners should block access under decking and raise sheds or garden buildings off the ground. Areas around garden furniture and hot tubs should be kept dry, with covers checked regularly. Wood piles should be stored off the ground, and compost heaps securely covered. Pet food should be stored indoors or at least elevated, and bird feeders with seed trays should be used to minimise spillage. Keeping gardens tidy by clearing leaves, debris and fallen fruit promptly also reduces shelter and food sources for rats.
Antill stresses that taking these simple preventative measures can make a garden far less attractive to rats and stop infestations before they start. With rat activity on the rise, early detection and careful management are key to protecting homes and outdoor spaces.
