As temperatures rise during summer, rats become more active, but pest control specialists suggest that one natural item—peppermint oil—can help keep them at bay in gardens and outdoor areas.
Why rats are more active in summer
Warmer weather brings increased rat activity as food sources become more plentiful. Residential neighbourhoods with wheelie bins, bird feeders, and compost heaps can attract these rodents, prompting experts to advise vigilance around sheds and outdoor spaces.
Peppermint oil as a deterrent
According to pest control professionals, rats are deterred by peppermint oil due to its strong aroma. Some homeowners use it as a natural deterrent around entry points and outdoor areas. John Whiteley Wilkinson from Acorn Environment Services explained that while natural deterrents may help reduce activity, prevention remains the most vital step.
John said: "Rats are constantly searching for food, water and shelter, especially during summer when outdoor activity increases. 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."
How to use peppermint oil
Specialists recommend soaking cotton wool balls in peppermint oil and placing them near sheds, bin storage areas, garden decking, entry points around pipes, and garages or outbuildings.
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.
John warned that rats can squeeze through remarkably tiny gaps and are highly adaptable. He continued: "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."
Signs of rat activity
Common signs of rat activity include droppings, scratching noises, gnaw marks, burrows near sheds or fences, and damaged bin bags.
While peppermint oil and other strong scents might help as part of a wider prevention strategy, persistent infestations should always be assessed by professionals. "If homeowners notice repeated signs of rat activity, it's important to deal with the issue early before populations increase," John added.
