Homemade Rat Or Mouse Poison

Last Updated: December 11, 2022

Commercial rat poisons work well, but they also include dangerous chemicals that might endanger the people and animals in your house. Instead, you can create your rat poison at home using ingredients such as plaster of Paris, cornmeal, or flour.

Even though these are less harmful, you should still try to keep them away from children and pets since they will eventually be mixed with poison to be given to invading rats.

Homemade Rat or Mouse Poison Recipes

The nocturnal, reticent rodents known as rats look for food, drink, shelter, and safety inside our dwellings. Rats frequently reside outside but enter a house only when they are hungry (at night).

Do you have rodents in the house? And they’re not your pets? Continue reading for natural methods to eliminate them and prevent them from returning.

Here Are Easy Recipes:

  • Baking soda poison 
  • Boric acid poison
  • Plaster of Paris poison

Supplies Required

  • Disposable gloves
  • Chicken broth
  • Sugar or chocolate powder mixture
  • Boric acid
  • Baking soda
  • Cornmeal or flour
  • Plaster of Paris
  • Jar lids

Here is Homemade Rat or Mouse Poison Recipes:

#1 Rat Poison Made from Boric Acid

Don your disposable gloves to prevent skin rashes. A bowl should contain a cup of boric acid. Boric acid should first have roughly a 1/2 tsp of chicken broth added. After each addition, thoroughly stir until the mixture has thickened to the point where it is difficult to stir.

1. A little extra boric acid can be added if it’s too thin. The rats will be drawn to the smell of the broth and finally ingest the boric acid, which will cause them to perish.

2. Form the paste into marble-sized balls. Create baits that are simple to move if necessary by placing 2 or 3 balls inside jar lids or other small, disposable containers.

3. Set up the baits where you have noticed rat droppings, as these are the sites where they are most prone to reappear.

  • Check out for dead rats or halt droppings in the baited regions.

#2 Rat Poison Made with Baking Soda

1. Don a pair of disposable gloves. 1 cup of cornmeal, powdered chocolate mix, or sugar should be combined with 1 cup of flour. Blend the mixture thoroughly before adding 1 cup of baking soda. After the rats are drawn in by the sugar or chocolate, the baking soda will quickly kill them.

2. Pour some jar lids with the rat bait about halfway full.

3. Place the jar lids with the bait anywhere you have seen rat droppings. Most likely, the rats will return to these locations.

4. Once you notice that there are no longer any new droppings, keep an eye out for signs that the issue has been resolved. Track down any dead rats.

What effects does baking soda have on rats?

Baking soda contains bicarbonate, which, when combined with the rat’s stomach acids, causes the production of carbon dioxide gas. Rats cannot expel the gas, so it accumulates inside of them and finally produces an internal obstruction or rupture.

#3 Rat Poison Made From Plaster of Paris

1. Wear your disposable gloves first. Add one cup of plaster of Paris to each of the following ingredients: cornmeal, sugar, and powdered chocolate. The mixture should be well-blended. Rats will be drawn to the fragrance of chocolate or sugar and eat the bait. When the plaster of Paris is consumed, it will kill the victims because it will combine with bodily fluids and solidify their digestive systems.

2. Spoon the mixture into the jar lids till it is almost half full.

3. Put the baited lids in places throughout your house where you’ve seen rat activity, especially where you’ve discovered droppings.

4. Keep an eye out for any dead animals in the neighborhood. Additionally, you should observe that new droppings appear less often or sometimes not at all.

#4 Outdoor Rat Traps That Are Secure For Use Around People And Animals

When using rat poison outside your home, take the following precautions to protect children, pets, and wildlife.

1. Collect a few unfilled plastic gallon milk jugs.

2. Locate a few areas outside your house where rats might reside, like around plants or even trash cans.

3. Blend some sugar with cocoa or chocolate powder. Alternatives include making one of the poison concoctions mentioned above.

4. Fill the milk with water only halfway.

5. Screw on the lid after adding some sugar or a poisonous concoction.

6. Create a hole in one of the areas where rats or mice are found. Once it is even with the ground, the jug must be fully submerged in the hole.

  • Disperse a little cocoa powder on the surface. Rats will detect the chocolate and pierce the dirt and the plastic jug with a hole, but it will only be big enough for them to fall in and drown.

#5 Areas Where A Rat Trap Can Be Buried Outside

  1. Near unused lumber or woodpiles.
  • Under untrimmed or unpruned bushes, vines, and tall grasses.
  • In the garden, beneath the stones.
  • Within the basements of buildings.
  • In addition to near garbage and compost bins.
  • Keeping Rats/Mouse Out of Your Yard.
  • Any garbage cans should have their lids on firmly.
  • Garbage cans should be closed and used to store any bags of trash.
  • Sealable containers should be used to store pet and bird food. Keep bird seed out of seed feeders and off the ground.
  • Put a lid on your worm bin or compost pile. The compost should not contain any meat or dairy products.
  • If any fruits or berries fall to the ground, tidy them up, then compost them.
  • Any dog waste should be cleaned up and disposed of.

#6 Self-Made Rat Bait Stations

None of those above poison mixtures should be used without a bait station if you have rats inside your house. Simply put, a bait station is a container that houses poison. Because of the following, you ought to employ a bait station:

  • It provides the rat with a more secure eating environment, increasing the likelihood that it will feel secure and consume more of the poisonous mixture.
  • Thanks to this, the poisonous mixture is kept out of reach of kids and pets.
  • Instead of scurrying off and dying inaccessibly far away, the dying rat is more likely to pass away in the station.

#7 Create Your Bait Station

In hardware stores, you can purchase metal, cardboard, or hard plastic bait stations. Making your own is another option. Consider using sturdy materials, such as plastic or wood scraps. Two entrances should be present at your bait station. Rats prefer to eat in areas with many exits.

Homemade Bait Station Types

  • A section of PVC pipe.
  • The rat can fit through two holes in an empty water jug or plastic milk.
  • A wooden container with two tiny holes.
  • A cigar container with two tiny holes.
  • Where to place indoor bait stations.
  • In the ceiling or wall insulation.
  • In confined areas.
  • Behind or beneath counters, cabinets, bathtubs, and shower stalls.
  • When things are kept in boxes or bags, such as in basements and attics.

#8 Using Rat Traps

The large, straightforward, inexpensive wooden “snap trap” is the best rat trap. They’re offered for sale in hardware shops.

How To Set The Trap

1. Use cereal, peanut butter-smeared cotton balls, raw bacon, apple, potato, or potato pieces to bait it. The bait needs to be fastened to the trap.

2. Set the trap near the rat droppings you discovered. Make sure both children and animals can’t access the trap.

  • Securely fasten the trap to the surface or a sturdy wall to prevent the rat from pulling it away.


Everyone should live in a home free of pests. This is among the primary reasons we construct our homes to be as secure and protected as possible. They wouldn’t want to expose our kids to the risks that come with pests since they are responsible parents.

It may take up to two days for the rat to pass away after ingesting the homemade poison. After being poisoned, a rat will stop eating, greatly reducing the possibility of further poisoning. But as was already noted, several things affect how potent the poison is: the proper placement of the poison.
