Items you need

Water; ammonia, bowl, and detergent.

Place one or more bowls in strategic positions where you know there may be rats.

Another easily accessible ingredient is black pepper which is found in most homes. As far as a rat is concerned, this is another hated substance with rats scurrying away in the opposite direction.

Items you will need

Black pepper is the same pepper that you may use for your food.


Enough pepper to sprinkle around critical areas.


Sprinkle small amounts of ground black pepper around corners and holes where you know rats hide in your home.

Peppermint Oil

Another strong smell that rats hate is peppermint oil which has a particularly pungent aroma. Rats are very averse to this scent!

This is another natural rat repellent that works, and it is not harmful to children or pets.

Items you will need

Peppermint oil.


A bottle of peppermint oil from health stores or other suppliers.


Place a few drops of peppermint oil around the potential sources of rats, any holes, or other places where you think they may congregate. You can also soak cotton balls in peppermint oil to deter rats.

Refresh with more oil every few weeks until the problem is eradicated.

In addition to peppermint oil, you could also try growing mint around your property. This will consolidate your attempts to keep rats away and can be a permanent feature.


Rats seem to dislike certain types of powerful smells, and onions are one such odor. Onions are renowned for their powerful smell and antiseptic properties.

They are completely natural and easily bought as part of any shopping run.

Items needed

As many onions as you feel you need to cover each area where rats may hang out! Don’t forget to buy some to eat too.


Slice an onion for each location and place a few slices in or near their burrow, hole, or rat’s nest.

Hopefully, they will quickly remember this and start avoiding your house.

Using the homemade repellent

Replace the onion slices every week until you see results.


Although mothballs aren’t homemade, they are often found around the home or are easily obtainable, and they also repel rats.

You don’t have to do anything in particular; obtain them and put them in the required places.

However, although they may repel rats they are also poisonous to humans and rodents. If you use mothballs, please wear gloves.

You may not want to use this method if you have children or other pets.

Items and ingredients

Mothballs can be purchased from many stores and DIY suppliers, but the cost is meager!


Place the mothballs around your house near holes or places that you know rats frequent. They can also be placed in attics and basements. If exposed to the elements, mothballs have around 4 to 6 weeks.

Make sure to replace them regularly to retain good results.
