DIY Rat Repellent: Easy Tips For The Clever Homeowner

We humans have been battling rats since forever.  Rats want what we have…shelter and food.  So the rats move in, and we do everything we can to get rid of them.
As a homeowner, a rat infestation is the last thing we want, or need.  If you’ve ever found rodent droppings or bags of food with holes chewed into them, then you know exactly what I mean.

So what can we do to get rid of these uninvited pests?  Is there an easy DIY rat repellent out there that actually works?  The answer is yes.

How To Tell If You Have a Rat Infestation

Rat infestations have unique signs and symptoms that you as a homeowner can easily pick up on.

The most common are finding rat droppings in and around the house.  Look under the sink, in the pantry, the garage, the basement and the attic.

Look for gnawing marks on food containers, furniture, walls and baseboards. Rats love to hide in the cozy spaces between the wall studs in our homes.

If you find any of these signs, then it’s time to take action.


Easy DIY Rat Repellent and Prevention

A quick search on Google and you’ll find a long list of DIY rat repellent ideas.  The problem is that almost all of these simply do not work. If you talk to professional rodent control experts, they will tell you that they have even used some of these “diy rat repellents” as bait to catch rats!

So what works?  I have found a few DIY rat repellent ideas that will actually work for you the homeowner.  I am saving the best tip that is 100% guaranteed to work for last.  

Plaster of Paris

The laster of Paris method of rodent control is intended to kill the rats. It is essentially a DIY rat poison. With that said, be sure to keep it away from kids and pets.

Mix together:

-3.5 oz of plaster of Paris with

-3.5 oz of cornmeal in a bowl

-1.5 cups of milk

Mix everything together evenly into a dough like texture. Then tear off small pieces and roll them into balls. Strategically place these small rat poison bait balls around the house. Note that over time, the Plaster of Paris will begin to harden, so you will need to replace them from time.

*Remember to keep these out of the reach of kids and pets.

Flour, Baking Soda and Sugar

Equal parts:


-Baking Soda


Mix all of the ingredients in a large bowl. Then place the mixture into smaller containers and strategically place the rat poison filled containers near the rodent infested parts of your house.

After eating the poison mixture, the baking soda begins to react with the rat’s stomach acid. This reaction produces bloating which results in death. It is said that the rats do not necessarily die instantly, but run to open grounds outside the house before dying.

Feline Hunters

Cats are an excellent way to eliminate and prevent rats infestations.

Cats are probably the most popular, time tested and proven method for rat control.  I live in a rural area surrounded by fields, so I tend to have a lot of rodents near by.  I have two cats and they are both always busy catching rodents. Once we introduced the two cats to our home, the rodent population was almost immediately eliminated.  If you are in a position to care for a cat, I highly recommend this DIY rat repellent method. It works.

Clean and Seal Your House

The best DIY rat repellent that is 100% guaranteed to work is to not let them in your house to begin with.  Locate and seal all of the holes and cracks that the rats are using to enter your house.

Many times in older homes, poorly maintained pipelines will oftentimes provide enough space for rats to enter the home. Locate the water shut off valve and look for evidence of these cracks or openings. These spaces can easily be filled with expanding foam.

Use expanding foam to seal spaces around pipes as a way to prevent rodents from entering the house.

After you make sure that all entry points to the inside of your home are sealed shut, there’s one last thing you can do as a DIY rat repellent.  Be sure to not leave any food lying around. Keep the area under your sink clean and free of food, or any other area you might keep your garbage. Keep your pantry clean. Do not let any food stay on the ground or spilled inside a drawer.

A rat infestation does not mean you have a dirty home.  Rats need shelter and they need food.  We have both.  And to them, its an open invitation to move in.

I hope these DIY rat repellent ideas work for you.
