Why Do I Have Rats In My Home?

Rats are Nimble and can maneuver themselves into the smallest of holes or crevices around your home. They are first and foremost, looking for food. They’re also trying to find the safe shelter for themselves and their offspring.

The need to find safety in your home creates the dilemma that we need to take care of. Rats are unwelcome guests for the most part, if we are not keeping them as pets in a cage.

Rats are also unable to handle cold temperatures during the winter. This is why many properties end up with rat infestations in colder seasons.

How Do I Prevent Rats From Entering My Home?

Before we get into the different types of DIY rat poisons that we can create ourselves, we might be able to prevent rats from entering our homes in the first place.

Here are the top 7 methods of rat infestation prevention:

  1. Frequent Cleaning
  2. No Trash Lying Around
  3. Avoid Clutter
  4. Cover holes, cracks and crevices,
  5. Avoid too many plants
  6. Treat Your Lawn
  7. Visit Your Unused Spaces Regularly

1. Frequent Cleaning

Frequent cleanings will help you determine whether or not you are noticing any rat droppings or any other signs of rat infestations. Remove anything that would attract any rats including crumbs.

Sweep, scrub and vacuum the floor. Don’t wait for a weekly cleaning session to keep your home free of rats. Clean as you go and don’t leave things dirty to clean up tomorrow.

2. No Trash Lying Around

Rats love trash. If you have trash bags in the room in your house or in the kitchen, this is a great place for a rat to rummage through.

Don’t give a rat the opportunity to enjoy tearing through garbage bags lying around in the garage, in front of your home or anywhere else if you can avoid it. Seal all your garbage in containers with lids and lock them if you can.

3. Avoid Clutter

The house that is full of clutter is also full of hiding spaces for rats. Avoid building up too many unused items such as clothes, or accessories. Rats are shy and timid and we’ll enjoy cluttered space as effective hiding grounds to remain undetected. You are making it easier for rats to hide and rest in your home. This is a good time to think about minimizing your possessions in order to keep rats away.

4. Cover holes, Cracks and Crevices

Rats are going to find their way to squeeze into your home through open holes or cracks. When the time is convenient for you, perform an inspection of your house.

Check every corner of your home carefully to make sure that there are no holes where a rat can come into your home.

Go through the garage, basement and attic carefully. Close up holes. These are the proactive measures that are so essential to maintaining a rat free home.

5. Avoid Too Many Plants

Plants are a popular way of creating a more natural, calm and serene environment around or in our homes. The problem is also that plants create great hiding spaces for rats that are shy.

Position outdoor plants further away from your home and especially the entrances or exits.

6. Treat Your Lawn

Treat your lawn and avoid pests like insects from entering your property. Once these creatures are in and around your home, they become enticing options for rat food. Rats will dine on these critters if they are available.

Start by treating your lawn with pesticides to keep them away in order for rats to find another place to look for food.

7. Visit Your Unused Spaces Regularly

The reason why rats love being in the attic or basement of your home is because most of us don’t go there often enough. We leave rats to enjoy the spaces without interfering.

It’s time to interfere. Create time to inspect these unused spaces for evidence of any rats such as droppings. Once you realize that you may have a rat infestation, it’s time to get rid of them.

Top 8 DIY Homemade Rat Poisons

It’s time to kill some rats. Sorry to all rat owners who care for them in cages. This section is not for you. We have a rat infestation and we are here to seek out safer, cheaper, but effective options of getting rid of these rodents.

Here are the top 8 Homemade Rat Poisons:

  1. Peppermint
  2. Moth Balls
  3. Ammonia
  4. Black Pepper
  5. Onions
  6. Boric Acid
  7. Baking Soda
  8. Plaster of Paris

1. Peppermint

Rats have a heightened sense of smell. If you put peppermint oil drops on a cotton ball and leave it near where you suspect rats to be living in your home, the scent will enter the lungs of a rat and cause them to stop breathing. Their lungs will shrink and they will have a hard time breathing.

2. Moth Balls

Place mothballs in the areas where you find rats. There is a chemical found in mothballs called, naphthalene. This chemical can suffocate a rat. Their blood cells will not be able to carry oxygen to their brain.

3. Ammonia

Ammonia is a powerful cleaning agent but also a poison to kill rats. Mix 2 cups of ammonia with 200 mL of water. You can also add two spoonfuls of liquid detergent and place all of these in a large bowl. The smell will attract rats but it will also kill them.

4. Black pepper

The smell of black pepper is sharp. Rat cannot inhale this scent the way we can. If the black pepper granules or a whiff of black black pepper in the air enters the lungs of a rat, it will be deadly.

5. Onions

Onions are poison for rats. Slice onions and place them in locations where you find rats. Onions can go rancid quickly, so it’s best to replace them each day.

6. Boric Acid Poison

Now it’s time for our favorite methods of homemade solutions to kill rats. We favor boric acid over any of the homemade remedies above.

Mix 1 cup of boric acid with chicken broth. Stir the contents well. Add more boric acid to make the liquid a little bit more lumpy. Rats will be attracted to the odor of the chicken broth. They will consume the boric acid and die.

Instead of enticing them to drink from a bowl you can create boric acid and chicken broth paste. Roll them into balls and place them on a flat surface as bait for rats to consume.

7. Baking Soda Poison

Baking Soda is a very popular method for killing rats. You can combine baking soda with a cup of cornmeal and sugar. You can also use a cup of powdered chocolate.

Add one cup of baking soda to this mixture and fill the inside of a jar lid with it. If you want, you can also turn them into balls. You will need to add more liquid such as water or milk in order to do so.

8. Plaster of Paris Poison

Mix Plaster of Paris with water or milk. Roll them into balls. Place these balls in different areas where you suspect rats to be. If the balls turn very hard, you will need to make new ones.


We hope these top eight methods of using homemade solutions to kill rats will help you out.  We prefer boric acid, baking soda, and Plaster of Paris as our favorite methods mixed with cornmeal, powdered chocolate or sugar.

Rats prefer to consume the poison in ball form over liquid form. You can serve it as loose powder or roll them up into balls by adding more liquid such as water or milk.
