Pest control specialists are urging homeowners to stay alert for heightened rat activity around gardens, sheds and outdoor spaces this summer, as warmer weather drives rodents to seek food and shelter. According to experts, one powerful household scent — peppermint oil — could make properties far less attractive to these pests.
Why Rats Are More Active in Summer
Rats become more active in warmer months because food becomes easier to find, especially in built-up areas where bins, bird feeders and compost bins provide irresistible sources. John Whiteley Wilkinson from Acorn Environment Services explained that rats are constantly searching for food, water and shelter, and outdoor activity increases during summer, making properties more vulnerable.
While natural repellents like peppermint oil may help reduce rat activity, Wilkinson emphasised that prevention should always be the top priority. “Strong smells such as peppermint can sometimes help discourage rats from lingering in certain areas, but homeowners should focus primarily on removing anything that attracts them in the first place,” he said, as reported by the Express.
How to Use Peppermint Oil as a Deterrent
Experts recommend soaking cotton wool balls in peppermint oil and placing them near potential entry points and outdoor zones. Key locations include sheds, bin storage areas, garden decking, entry points around pipes, and garages or outbuildings. The pungent aroma is known to repel rats, making these areas less inviting.
Additional Prevention Tips
Homeowners are also advised to keep outdoor bins tightly sealed, avoid leaving pet food outside overnight, clean underneath bird feeders regularly, trim overgrown vegetation, and block holes and gaps around properties. Wilkinson cautioned that rats can squeeze through remarkably small openings and are extremely resourceful when seeking shelter. “People often underestimate how quickly rats can settle near a property if food and hiding places are available. Even small amounts of waste food or cluttered outdoor areas can encourage activity,” he added.
Signs of Rat Activity
Common signs of rat activity include droppings, scratching noises, gnaw marks, burrows near sheds or fences, and damaged bin bags. Experts stress that while peppermint oil and other potent scents might assist as part of broader prevention strategies, ongoing infestations should always be evaluated by professionals. “If homeowners notice repeated signs of rat activity, it's important to deal with the issue early before populations increase,” Wilkinson concluded.
