Rats are elusive and quick, and they breed a lot each year, hiding in the walls, ceilings, cupboards, and other crevices of your house. How then can we keep them away? 

The alternative of using poison bait, which can be harmful to children and pets, is not reassuring as snap and glue traps require dealing with dead and dying rats.

Some people turn to black pepper in their hunt for a natural remedy to get rid of rats in the house, but is it actually successful in halting an infestation?

What is black pepper?

Known as a peppercorn, black pepper (Piper nigrum) is a flowering vine in the family Piperaceae that is grown for its capacity to flavor food, serve as a preservative, and provide heat to a dish. Along with its ability to enhance flavor, black pepper has many health advantages.

Does black pepper keep rats away

Rats and mice have a strong sense of smell which draws them to discarded food. Since mice rely so heavily on their strong sense of smell, the strong potency of black pepper, which contains piperine, will deter them from getting closer to the source and keep them away.

Rats don’t die from deathly sneezes from black pepper. Black pepper repels rats from a spot permanently rather than simply killing them.

Piperine from black pepper makes rodents physically uncomfortable and inflames their noses. 

This article will focus on how to get rid of rats with black pepper. In further detail, let’s look at how to use black pepper to kill rats. 

How to use black pepper to kill rats

If you choose to use black pepper to deter rats, you can sprinkle it around areas where rats may be present, such as near food sources or entry points.

However, it is unlikely to have a long-term effect and may not be a practical solution in many cases.

The presence of piperine in black pepper is quite high, and piperidine, a constituent of piperine, has been evaluated for its toxicity towards rats. The reported LD50 value for piperidine is 514 mg/kg.

Although this value is not as potent as commercial rat poisons, which typically have an LD50 of 1-2 mg/kg, it is still significantly higher compared to other homemade rat poisons such as baking soda and Plaster of Paris.

Will black pepper keep rats away

Rats have a highly developed sense of smell, and they can quickly adapt to new odors. While black pepper may temporarily repel rats, it is unlikely to have a long-term effect.

Moreover, using black pepper to deter rats may not be a practical solution in many cases, as it would require large quantities of pepper to cover an entire area.

Using black pepper as a rat deterrent is not recommended as it is not an effective method for controlling pests, and it can also be harmful to other animals and humans.

While black pepper may have some repellent effect on rats due to its strong odor and taste, it is unlikely to be lethal or cause harm to them.

How to get rid of rats with black pepper outside the house

1. Clean up Debris

Pick up any garbage, food scraps, and potential water sources. As a result, they are deprived of food and are forced to seek it elsewhere.

Check for any obvious entryways the rats are using once you’ve cleaned everything up properly and block them. This might involve things like cracks in the floor, broken pipes, and holes in your house’s foundation. 

2. Examine the high-activity areas

In order to effectively place rat repellents, after cleaning, identify the regions with the highest rat activity. Perform a thorough inspection of your entire house, looking for any little gaps that you suspect rats are using.

Take note of any locations where you have previously spotted rats and rat droppings as well.

3. Place black pepper. 

The regions where rodent activity is highest in the locations you’ve identified should be treated with a significant amount of crushed black pepper.

These places could be in or near garbage cans, cabinets, cupboards, washers, dryers, refrigerators, along walls, and so on.

4. Check the hook, crannies, and nests.

Additionally, if you want this technique to be as powerful as it possibly can be, you’ll need to find the rat nest and thoroughly cover it and its surroundings in the crushed pepper.

This should considerably irritate the rats and force them to permanently leave.

5. Repeat this process until all the rats are gone 

Repeat the procedure of locating their hiding places, installing black pepper barriers, and sprinkling black pepper liberally in selected locations where you suspect they might be.

The rats should disappear once you locate the ideal quantity, which will be sufficient for them to nibble and run.

6. Trim All Trees And Shrubs

Rats and rodents are exceptional climbers. Wood rats get their name because they prefer to stay in wooden places. Long tree branches that extend to a rooftop is one easy way for rats to get into your home.

Trees and shrubs should be trimmed at least 3 feet away from the outside of a building.
