If a sharp, rotting smell suddenly fills a corner of the house at night and a small dark creature darts into a crack before you can even react, shrews have likely moved in. They may look like ordinary rats at first glance, but the trouble they cause runs deeper: shrews spread a foul odour through the house and dig up potted plants until the roots give way.
Why do shrews move into a house in the first place?
Shrews usually settle into homes where moisture and easy access to food are available. A damp patch under the sink, a dark corner in the basement, or food left out in the open is often enough to draw them in. Once they find a foothold, they burrow into the soil of flower pots too, weakening plant roots in the process.
The health risk is just as real
Shrews are not just a smell and a gardening problem, they are a genuine health concern. Their saliva and bodies carry various bacteria and parasites, which raises the risk of skin allergies or infections for anyone living in the house. That is exactly why getting rid of them matters beyond just the odour, and the good news is that none of it requires poison or killing the animal, a handful of natural, home-based smells does the job.
Five home remedies that push shrews out
The sharp scent of peppermint oil
Shrews cannot stand a strong minty smell. Soak thick cotton balls in peppermint essential oil and place them in spots where the animals are most likely to appear, such as dark vents, doorways or corners of the house. The intensity of the smell feels suffocating to them and they abandon the spot almost immediately, while the house is left smelling fresh.
A sharp garlic and onion spray
Garlic and onion have a pungent smell that people may enjoy but shrews simply cannot tolerate. Crush a few cloves of garlic along with onion, boil the mixture in water, let it cool, and pour it into a spray bottle. Spraying this liquid around corners and burrow openings sends shrews running far from the area.
Red chilli powder or cayenne pepper
For a more lasting fix, red chilli powder works as an effective weapon. Sprinkle chilli powder or cayenne pepper in the spots where shrews tend to hide or pass through. Contact with the powder causes a sharp burning sensation in their nose and skin, and the fear of that discomfort keeps them from returning to the same path.
Used coffee grounds
Instead of throwing away the leftover powder from a morning coffee, dry it out and scatter it along the paths shrews use to move around. The strong yet earthy aroma makes the creatures uncomfortable enough to stay away, and as a bonus, it also helps cut down on other odours in the house.
A white vinegar solution
The sharp, sour smell of vinegar keeps shrews at bay as well. Mix equal parts water and white vinegar into a solution, pour it into a spray bottle, and spray it around corners, basements and under sinks. Besides driving shrews away, it also wipes out the scent trails they leave behind, so they cannot find their way back along the same route.
Keep the house clean and dry
Alongside these remedies, a few habits around the house make a real difference. Never leave food items out in the open and always keep the lid on the dustbin, so shrews get no reason to come looking for food indoors. It also helps to keep corners of the house dry and well-ventilated, since dampness is what draws shrews in the most.
Following these five simple and safe remedies can make a house shrew-free without any violence or chemicals, and get rid of the strange smell for good.
