Rats and mice can be a persistent problem in UK homes, particularly during the summer breeding season. However, a simple and inexpensive kitchen ingredient — garlic — may offer a natural solution, according to DIY expert Glen Peskett from Saxton Blades.
Why Summer Increases Rodent Activity
Summer is a critical breeding period for rats and mice. During this time, they are hungry, seeking shelter, and reproducing rapidly. Homes provide ideal nesting sites, and failure to prepare or spot early warning signs can quickly lead to a full infestation. Not only is removal costly, but rodents also pose health risks through disease transmission.
Peskett explained: "Garlic is a favourite all around the world, it smells amazing, has health benefits and transforms any dish you put it in. But for rats? That strong, pungent smell is their absolute nightmare."
How Garlic Works as a Rodent Repellent
Rats rely heavily on their sense of smell to navigate and find food. Garlic contains strong sulfur compounds that overwhelm their olfactory system, causing disorientation. These compounds are also associated with toxic substances in the rodent's memory, naturally deterring them from entering homes.
Garlic is budget-friendly: a four-pack from Asda costs just 87p, equating to around 22p per bulb. This makes it an accessible repellent for households.
Practical Application Tips
To use garlic effectively, place cloves around entry points where rodents are likely to gain access. Key areas include basements, garages, kitchens, and lofts. Ensure cloves are positioned near gaps and doorways around the exterior of the home.
Other natural repellents such as garlic oil, cayenne pepper, and apple cider vinegar can also discourage pests.
Additional Rodent Prevention Measures
Repellents alone may not be sufficient. Reducing clutter removes potential nesting sites. Food waste attracts rats, so keep bins firmly sealed, empty them regularly, and clean up spillages promptly. Inspect for cracks, especially under doors or vents, and seal them — even tiny openings can allow rodents to squeeze through.
