The sight of mice in the home is enough to leave any homeowner with an uneasy feeling. It feels like an invasion of privacy and a health hazard, so it only makes sense to repel them however possible. So, do coffee grounds keep mice away?

You typically cannot repel mice with coffee grounds, particularly if they are moist. Mice are drawn to aromatic food and waste so strong-smelling coffee grounds can easily attract them. Dry coffee grounds may not attract mice, but used coffee grounds likely will because rodents love moisture.

Other household items like vinegar, peppermint tea, and ammonia can repel mice. Coffee grounds aren’t as enticing for mice as fruit and pet food, but they don’t work as a repellant. Follow along as we explore why coffee grounds don’t keep mice away.

Do Coffee Grounds Keep Mice Away?

Coffee grounds don’t keep mice away, and they may even attract them. Rodents don’t seek out coffee grounds as much as they do sweet fruits and pet food. However, particularly aromatic coffee grounds may attract mice and other rodents.

Sweet coffee grounds in particular are the most likely to attract mice. However, many homeowners use coffee grounds to help absorb the odor of mouse droppings and dead mice. Coffee is aromatic enough that it can cover foul smells and potentially absorb them from the air.

Mice cannot safely consume coffee grounds because of the caffeine content. They don’t necessarily know that the caffeine will harm them, however, so mice nibble coffee grounds without hesitation. Use dry coffee grounds if anything because wet coffee grounds may attract mice due to the moisture.

What Smells Keep Mice Away?

The smell of vinegar, ammonia, peppermint, and clove keep mice away. You can even keep mice away if you put out unbrewed bags of tea that contains mint. Try to put the tea bags near entry points that the mice use or areas where they tend to nest.

Household items like vinegar and ammonia can both repel mice and help clean the area. It may sound gross, but even cat urine can repel mice and many homeowners use it. However, that should be a last-ditch effort because the smell of cat urine is as difficult to remove as mice.

Dryer sheets can also repel mice because they contain strong chemicals and artificial scents. Mice avoid cinnamon as well, but you must be careful because the odor may attract other pests. Leave out some cayenne pepper in a dish if all else fails because mice typically hate the scent.

Are Mice Attracted to Ground Coffee?

Most rodents aren’t necessarily attracted to coffee grounds. However, they will gnaw and nibble if given the chance. The reason is that mice have to forage for their food. And so they taste test everything before settling on a meal.

Meanwhile, people typically pour their used coffee grounds in the trash with other food waste. Then, that attracts rodents due to the smell of the rotting food. So, try to put your grounded coffee in its own container. Or send it through the garbage disposal in your kitchen sink.

DID YOU KNOW: Field mice love to forage for old eggshells in the trash, but they usually avoid leafy greens and coffee grounds.

Is Coffee Toxic to Mice?

If a rat or mouse consumes too much coffee, they could get sick or die. Coffee grounds can be toxic to rodents in high doses. Plus, research shows that caffeine in high doses can suppress a mouse’s locomotion, meaning it can’t move correctly. So, be careful when spreading a strong brew.

Since mice aren’t attracted to coffee, there’s not a lot of concern about caffeine content. But just in case, use a caffeine-free alternative if you’re spreading coffee grounds to get rid of foul odors.

What Is the Best Natural Mouse Repellent?

Natural rodent repellents can be effective at disbanding a rat infestation. That’s because they play on the innate behaviors of mice. For example, rodents don’t usually like strong odors and foul smells. And that’s especially true if those odors are from pepper.

Specific types of pepper repel mice and other rodents naturally. They’re also inexpensive and easy to use. You can even create a simple spray with common black pepper, crushed red pepper, or cayenne pepper.

Using natural pepper spray does not hurt mice but merely shocks them into remission. So, you can spread it around any holes or cracks you find. Then, the rodents can’t nibble on the flakes or gobble up your coffee.

NOTE: Some types of pepper can be toxic to rodents if ingested in large quantities.

What If Rats Infest a House?

A rodent infestation isn’t just annoying. It can be dangerous too. For one, mice can carry infectious diseases that are harmful to humans and other animals. Plus, they’re prone to biting when scared and they can leave behind bacteria-laden feces all over your house.

DID YOU KNOW: Rats were responsible for carrying and spreading the bacteria that caused the Bubonic plague.

When All Else Fails

You can’t allow mice to run freely around your house, even if you think they’re cute. And there’s nothing wrong with wanting to repel them naturally. But what happens when they just won’t go away? At that point, you may have to call a professional exterminator.

Professional extermination services can be expensive. So, call ahead to get some quotes and compare prices. Then, try to reduce the problem on your own to help cut costs. And if all else fails, have a contractor evaluate your property for potential danger zones.

Summing It Up

You cannot repel mice with coffee grounds in most cases. Wet coffee grounds are likely to attract mice due to the strong odor and moisture. Dry coffee grounds won’t attract mice as much, but they won’t repel them either.

You can use coffee grounds to cover up the smell of dead mice or mouse droppings, however. Use ammonia, vinegar, peppermint tea, and dryer sheets to keep mice away instead. Put dryer sheets or tea bags in areas where mice enter your home and nest to repel them.
