Rodents are known for their heightened sense of smell , a necessary adaptation due to their poor vision. To deter these pests, households can utilize strong scents that will "overpower" their olfactory senses.
Mice and rats "hate the smell of lavender". Therefore, using a lavender-scented spray or even better, growing a lavender plant, can naturally repel them from your home.
You could also create your own solution by mixing a quarter to half a cup of flowers with one-quarter cup of water in a spray bottle. Shake well before each use and spray surfaces in affected areas until they're wet but not dripping, reports the Express .
Replace this solution monthly to maintain its freshness and effectiveness.
Citrus oil
Rats and mice detest the smell of citrus oils because they contain limonene, a compound found in lemons, oranges, and grapefruits.
Limonene is also present in many cleaning products like soaps, detergents, and disinfectants, giving them their fresh and clean scent.
Citrus oils such as lemon and orange are also "very effective at keeping rats and mice away" from specific areas or objects.
Citrus oils pack a punch with their potent aroma, so it's wise to use them with a light hand or mix them with water before treating any spots that need attention.
Peppermint oil
Peppermint oil is touted as "effective" in sending rats and mice packing due to their aversion to the menthol scent.
Mice perceive the smell of peppermint oil as a signal of danger and fear, prompting them to "avoid areas" where the scent lingers or to "stay away from it" altogether.
It's a go-to for DIY mouse repellents, with its robust fragrance acting as a deterrent. A few drops on cotton balls placed in mouse-prone hideouts can do the trick.
Chilli powder
Chilli powder is another top pick for crafting your own rat deterrents because it's "inexpensive and easy to obtain at most grocery stores".
Mix about two tablespoons of chilli powder per litre of water, then pour into your spray bottle or hand sanitiser container.
Experts say: "This is an effective home remedy for getting rid of mice because it smells terrible to them and they won't stay around long enough for their sense of smell to become accustomed to it."
Just scatter some chilli powder in suspected mouse hotspots, like behind cupboards or beneath furniture.
