Does Xylitol Kill Rats

Spread the love

Xylitol is sugar alcohol extracted from plants, vegetables, and fruits. It is commonly used to substitute sugars. Xylitol is readily available in the market but does xylitol kill rats?

No, xylitol does not kill rats. Over the past few years, researchers have tried various concentrations of xylitol on rats to determine toxicity profiles, but nothing substantial has been established.

In this article, we will discuss the properties of xylitol and how it can affect rats. Moreover, we will enlist a few poisons that have proven effective in getting rid of rats from the household. A few home remedies also show good results when it comes to killing rats.

Can Rats Have Xylitol?

Other than being used for rats, xylitol has multiple functions. It acts as a natural antibiotic against bacteria that cause ear infections. It is preferable to ordinary sugar as it does not cause tooth decay.

Xylitol is also used in sugar-free candies, chewing gums, and mints. However, the use of xylitol can be toxic for dogs. Studies have suggested that dogs must immediately be taken to a vet.

Rats can usually have xylitol. If that is commonly used in your household, it is bound to be discovered by a rat due to its sweet smell. Rats get attracted to it. However, xylitol is not sufficient for killing rats.

Is Xylitol Toxic To Rats?

In 1977, some researchers did an experiment in which they administered xylitol to rats. That resulted in hepatic dysfunction. The xylitol was administered continuously for six days at a stretch.

However, in later studies, the xylitol was administered to rats for 14 days. The following doses were experimented with, 1.25, 2.5, and 10g/ kg, respectively. After a few days elapsed, their blood serum analysis was done so that the researchers could study the effects of xylitol on the body of rats and confirm previous findings.

On day 14, these rats were killed, and their organs were studied. Histological studies were carried out on all rats. The liver was studied most importantly. On the bright side, no hepatotoxicity was reported in such rats.

All blood and serum parameters like bilirubin and serum alkaline phosphatase were within the normal range. Furthermore, no anomalies were reported. That is why the researchers concluded that the previous findings were perhaps false, and their results show no signs of xylitol toxicity in rats.

Xylitol Toxic Dose

The toxic dose for dogs is 75-100mg/ kg. This dose is sufficient to cause hypoglycemia in the dog. However, the preferred dose for some dogs is greater than 500mg/kg. Doses greater than 0.5g/kg cause acute liver failure in the dogs. 

However, no such reports have been cataloged for rats. Some researchers have carried out experiments on rats in which they were administered xylitol via subacute inhalation. The rats were given a dose of up to 5 g/m3

No adverse effects were observed on rats. However, some of them developed profound diarrhea. Some rats, though, had already adapted to the concentration of xylitol; that is why they did not experience any side effects. 

To sum it up, xylitol did not develop toxicity in the rats, and the highest concentration administered was not enough to kill them. 

What Is Poisonous To Rat?

There are several rat poisons available on the market. In this article, I will list a few main ingredients of those poisons and how they kill them. 


It is one of the most effective ingredients in rat poisons. It acts as bait to attract rodents and then kills them. It is more commonly known as super-warfarin. This is because it has a more prolonged action span time than the normal Warfarin. 

2) Fumarin 

Fumarin is a type of anti-coagulant that kills rats in several days. Its working mechanism includes the depletion of vitamin K from the rat bodies. This particular vitamin is crucial for the blood clotting process in rats. 

3) Warfarin

Warfarin is the most renowned anti-coagulant agent that works in the rat’s body. It has the exact working mechanism of fumarin, but it acts fast, and the rats die faster after its intake. 

4) Toxic Foods

Numerous toxic foods kill off rats. These include licorice, blue cheese, bitter almonds, and poppy seeds. Though they may not be able to attract rats on their own, they act effectively in killing them. Another essential food is green potatoes. Rats are vulnerable to them. 

What Kills Rat Instantly?

It is not necessary for a rat to kill rats instantly; you can adopt many other methods to eliminate the rat population.

The best results have been reported by using a snap trap. It is also a very convenient method. Usually, the traps are baited with peanut butter, which is cheap and attracts the rats to the snap traps.

Once inside the snap trap, a rat is unable to escape. Then you can poison the rat. This method has no flaws unless the snap traps have a loose hinge.

The baiting method is a clever technique. The drawback of using rat poison repeatedly is that once the rat sniffs it, it remembers the smell and knows to avoid consuming it. These are some of the self-learning innate behaviors of the rat.
