Mice are a common pest, but that doesn’t mean that you need to tolerate rodents living in your home.
Finding methods to repel mice is the simplest way to keep them away from your property.
The question does human urine repel mice is best answered by first looking at the science of mouse behavior.
Predator and prey
Mice have two types of scent receptors.
The first type allows the mouse to find food and water using it’s nose, while the second is designed to help the mouse identify and avoid it’s natural predators.
The second type of scent receptor is located in the rodent’s brain. When the brain’s scent receptor is triggered, the mouse either runs or hides to avoid becoming prey.
This survival instinct may be the reason urine repels mice.
In general, mice avoid other mammals, including humans, as part of their instinct to survive.
The odor of human urine tells mice and other pests that they aren’t welcome in the space.
Although human urine isn’t a fail-proof way to eliminate pests, the odor does deter a wide range of pests.
With regular applications, urine can reduce the number of infestations you have in your home and on your property.
Is human urine safe?
Generally, urine from a healthy person is bacteria-free for up to 24 hours after it leaves the body. While urine is bacteria-free, it can have a distinct scent that may be unpleasant.
To use human urine to repel mice without leaving a strong scent, dilute the urine with water before using it in your garden.
Use about nine cups of water for each cup of urine to make a mildly scented solution that determine rodents.
Some other tips to safely use urine to repel outdoor pests include:
- Collect fresh urine for each application, and dispose of any leftover mixture in the toilet after each application.
- Wash your hands thoroughly after applying the mixture.
- Sanitize your sprayer and any other equipment that you use to mix or apply the solution.
- Only use clear urine from healthy adults.
- Avoid spraying plants and landscaping features with the solution. Urine can occasionally cause discoloration on plants, including grass.
It generally isn’t recommended to use urine for indoor pest control, but you can safely create a perimeter around your property with the diluted urine solution.
You can also combine urine with other natural repellants to maximize it’s effectiveness.

Long-Term Pest Solutions
The question does human urine repel mice isn’t all you need to ask if you have a pest problem.
Usually, mice enter the home during autumn to find a cozy space to spend the winter.
If you have mice indoors, the best deterrent is to seal your home.
Sealing your house carefully prevents rodents from coming inside. Look for cracks along baseboards, in attics, around plumbing pipes and near doors.
Seal all cracks with caulking to keep mice outside.
Other ways to keep mice outside include:
- Seal larger holes with steel wool.
- Remove food sources, such as pet food.
- Fix any leaky faucets to eliminate water sources.
To keep pests from nesting on your lawn, store all items of the ground, including firewood, and keep debris like fallen branches off the lawn.
If you have holes in your lawn, use a mixture of diatomaceous earth, diluted urine and essential oils to cover the hole’s entrance.
The strong scent of essential oils helps repel rodents living inside the holes.
Alternately, apply a 10 percent urine solution to the entrance to deter rodents. This methods works to deter several types of rodents, including voles and ground squirrels
Consistent Pest Control
Deterring mice takes consistent effort over time, especially when you want to use natural pest control methods.
To maintain a pest-free property, reapply the diluted urine solution frequently.
Try using a stronger urine solution you didn’t notice results within a short time.
As part of your pest control routine, check your home and property for new signs of an infestation each time you apply the mouse repellent.
Signs of an infestation include seeing mice, finding rodent nests and finding mouse droppings.
If the mice are moving inside, you may notice small holes along the bottom of exterior and interior walls.
You can safely add essential oils the urine solution to increase the effectiveness of the mixture.
Essential oils are very condensed, so you only need to add a small amount to your solution.
For ten cups of diluted urine, for example, you only need to add about 30 drops of peppermint or lemon citrus oil.
Black pepper essential oil is also available. You can use just one of these essential oils in your mixture, or you can add all three oils to the mixture for a rodent-repelling boost.
With a little time and a consistent routine, you can encourage mice and other pests to leave your property using safe, natural methods like human urine, essential oils and plants.
