What Is the Best Way to Exterminate Rats and Mice? | Tips and Guide

Written by Thomas Matthews

Rats and mice are disease carriers. Apart from that, they can also cause structural and item damage to homes and businesses.

So, what’s the best way to exterminate rats and mice? One of the best ways is to use snap traps. Just mix two parts of peanut butter with a portion of boric acid. Boric acid is highly poisonous to rodents, so once they eat it you can expect your pest-related problem to be solved promptly.  

However, if you’re not into snap traps, there are other available methods that you can use. You can opt for either baking soda or onions as an alternative solution for your rats and mice dilemma.

Are Rats and Mice Safe to Have Around Your House?

Are Rats and Mice Safe to Have Around Your House

Rats and mice aren’t safe to have around your house. This is because these pests are known to carry diseases, such as:

  • Hantavirus—a severe respiratory disease that can be fatal if not treated right away. It’ll drop your blood pressure, and your organs will start to fail.
  • Leptospirosis—a bacterial disease, which can lead to meningitis, liver failure, and possibly death if it’s already in severe form.
  • Tularemia—a rare disease that causes ulcers in your mouth or skin, enlarged lymph glands, muscle aches, and more.
  • Salmonella—a bacteria that causes cramped stomach, diarrhea, fever, vomiting, and headaches.
  • Lymphocytic choriomeningitis (LCMV)—is an infectious disease that can cause hydrocephalus. You may also experience pain in different parts of your body, such as the chest, joints, and even testicles. 

Rats vs. Mice | Which Are Worse?

Rats vs. Mice

Both rats and mice are destructive pests. Although rats and mice are similar in appearance, rats are much larger than mice. Rats also have long, hairless tails, while mice have hairy ones. The size difference gives an upper hand to mice when it comes to the ability to access small openings in your home.

However, when it comes to aggressiveness, rats are much worse as they’re known to bite.

Do Onions Kill Rats?

Do Onions Kill Rats

Onions can’t kill rats, but they are an excellent deterrent. All you have to do is put sliced raw onions near the infestation location or where you normally find these pests and wait for the results.

Does Peanut Butter Kill Rats?

Does Peanut Butter Kill Rats

Peanut butter can’t kill rats but it’s a great choice to couple with snap traps or used as bait with boric acid. Just add one part of boric acid to your peanut butter (two parts) and form it like peas shape and size. Leave the peanut butter-boric acid mixture overnight near the affected areas and see the result.

On the other hand, you can also use plain peanut butter without the boric acid. Just put the plain peanut butter on a snap trap, and it’ll kill the rats and mice that fall into the snare instantly.

Does Baking Soda Kill Rats and Mice?

Baking soda can kill rats and mice when ingested. All you need to do is mix it with a bait such as chocolate powdered mix or cornmeal with sugar in it. The chocolate will entice the rats and mice, while the baking soda will slowly kill them after ingestion. This is due to the bicarbonate element present in the powder reacting to the acid in the rat’s stomach.
