30+ Different Types Of Rodents In The World (With Pictures)

Rodents and humans always had an interesting relationship toward each other. While we consider them dangerous and destructive, it is always inevitable to give them shelter through our homes. It is also quite hard to eliminate them after they have established themselves in our living spaces. 

But did you know that there are other types of rodents out there? In this post, we shall look at some of the most common types of rodents as well as some essential FAQs to help in mitigating the problem of their presence. 

What are rodents?

Rodents are mammals that are identified because of their single-paired teeth that continuously grow throughout their lifetime.

Due to their survival instincts that allow them to survive in the wild and in human-made environments, they are considered as the most diversified mammalian species out there. 

Some rodents are extinct because of predators present in the living areas but are still high in population as they have different types and species which can be found anywhere throughout the world. 

Rodent facts

Rodents, though small, have a huge, interesting fact that you probably still do not know. So, we lined up some interesting facts you need to know talking about rodents. 

1. Rodents are lurkers

Most rodents enjoy their life outside. Some enjoy the mud, the waters and some enjoy the company of humans.

Mostly nesting outside, on thick shrubs, grasses, fields, and other areas. They are very active animals, can be friendly and dangerous depending on the type, but they are most likely to be just lurking around.

2. Rodents are crazy about chewing

Whatever they feed on, they are crazy chewers. They destroy papers, wiring, cement, brick, wood, clothes and other more through their continuously growing teeth. Plus, with their agility, you cannot catch them even if you see them. 

3. Rodents reproduce like crazy

Rodents are excellent when it comes to reproducing. They grow their tribe many times a year so it is really a challenge to eliminate them. Mice can have litters of five or six babies every three weeks and rats can produce litters 15 times per year. 

4. Some rodents can swim

Rodents though not all types, can swim and are water lovers. Not a lot of people know about this interesting fact. So, if you are one, you may research the types of rodents which are excellent swimmers. Rodents who are fond of water survive toilet flushing and can walk in waters for a maximum of three days. 

5. Rodents don’t throw up

Rodents physically cannot vomit or burp.  Unlike humans, Rodents cannot choose what they eat and drink especially those that are found at home that is why poison is the most effective at killing them.

Rodent lifespan

Rodent lifespan is dependent on their type. Some are just more short-lived than others because they are outdoors and in constant exposure to prey. On the other hand, some may live for a year or two while some notable others could live for up to 10 years if the environment is viable or if they are adaptive to their changing environments. 

Types of rodents

There are a lot of types of Rodents. Depending on their habitat, features and characteristics, here is the list of the types of rodents which can make you distinguish one from the other. 

1. Agouti

This type is likened to guinea pigs. They are so much alike but differ in the size of their legs and species size.

Rodent prevention tips

Dealing with rodents has been a challenge to humans as they are not easily taken care of. They are prolific in reproducing, they are very adaptive, and they nibble on almost anything. If you are looking on how to prevent rodents from entering your homes, there are the easiest tips for you to master. 

  1. Seal up. Seal every hole inside and outside your homes. Make sure that there’s no entry point for them not to invade your space. Remember that once they enter the home, there is a high chance of harmful effects they will give. Do not give them a chance to play around and enter your homes. 
  1. Trap up. When dealing with rodents, the most common way of killing them is to trap them with the food they love which makes it easy for homeowners to catch them. Though rodents are very smart, they can smell and observe the things happening around them, many are still killed by the traps humans make as they love to chew, it is inevitable for them to stay away especially when it comes to food. 
  1. Clean up.  Whether small or big, few or many, always make sure that there is no food available in the ground or any part that can be reached by rodents. Make sure to make your home as clean and neat as possible. Food in the ground attracts rodents so if they have already invaded your house and found an area for nesting, have an extra effort cleaning the home. 

FAQs

Aside from what we have just covered, there are also some notable FAQs that you should be aware of when it comes to the types of rodents out there. This could help you in further preventive tips and in getting to know the ones that need to be immediately expelled. 

How many types of rodents are there?

Mostly non-flying mammals, there are more than 1500 recognized species of rodents in the world. They compose 25% of all the overall number of known living mammals out there. They are categorized into different subspecies, from destructive ones, to house pets, and the like. 

What animals are classed as rodents?

Given their range and number, there are more popular rodents because of their number and behavior. Some of these include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters.  

What looks like a rat but bigger?

Nutria or mostly called Coypu. From features to behaviors, they are the most comparable to rats. As a matter of fact, they are mostly called the large rat as they grow from 28-42-inches in length. They are also burlier and with longer tails. 

Are lagomorphs rodents?

Historically, they are considered rodents because like rodents, they also have continuously growing teeth. But today, they are already considered two different species, with a long, separated evolutionary histories and now have many recognized differentiations which include the number of incisors present in lagomorphs. 

What is the largest rodent alive today?

The largest considered rodent alive up to this date is the capybara or the Hydrochoerus hydrochaeris that is found in South America which weighs about 130 pounds. Some honorable mentions in this category would be the coypu, muskrat, the Patagonian mara and the cape porcupine. 

What time of the day are rodents most active? 

There is no specific time but they are known to be most active during dusk, late night and dawn. You can spot them or know that they are there through their droppings but it would really be hard to catch them on your own. You would also not want to do that because they carry with them infectious diseases. 

What time of the year do mice infestations usually happen? 

During the colder months. Their scavenging is limited during the cold months and the harsh outdoor environment could kill them. Hence, during these periods, they find their way into the humid home, and take niches in secluded areas, in the basement, in the ceiling and take food from pantries. This is also the time when they are most prolific in reproduction. 

Conclusion

Rodents are very interesting mammals. Indeed, they are on two sides of the extremes since there are types that are overly dangerous while some can be kept as house pets. The diversity that they have and their individual behaviors are enough to keep them striking, always. 

Much interest is given to those with larger sizes and those that can be destructive. The destructive ones almost always require professional help. They are great in reproduction and you might not know the extent of their population size without help. Also, be hygienic always if you want to evade their wrath.
