Rodents are classified by a single pair of continuously growing incisors in both their upper and lower jaws; the length of their incisors are maintained by gnawing, which is how they eat. The diet of Rodents usually consists of seeds and plants, but some species do have more varied diets. Historically, Rodents have been keep as pets, used as laboratory animals, and treated as pests. Rodents accidentally introduced as invasive species to new ecosystems, most notably islands, have been seen to wreak havoc and cause extinction of naturally-occurring species. Rodents are found on all continents, except Antarctica, and are the only species, besides Bats and Sea Lions, to reach Australia without human introduction.

What do rodents eat?

A rodent’s diet depends on the species as well as habitat. For example, mice and rats are able to carry a flexible diet, and quickly adapt to the food available in their surroundings. Squirrels and beavers have more specific food requirements. Beavers exclusively eat plants such as grass and twigs. Rodents generally eat nuts, meat, fish, fruits, berries, and food scraps.

How do you keep rodents out of a garden?

In order to keep rodents out of a garden remove any shelters they have such as brush piles and tall grass, remove food sources, control lawn grubs, and maintain the garden clean by keeping garbage and recycling bins clean. Also seal any holes, place fences, and place mesh tubes around any plants to prevent rodents from eating them.

Where do rodents live?

There are about 2,050 species of rodents and these make up most the most diversified mammalian order. Rodents live all over the world except Antarctica. They can be found in almost every single country, as well as every type of habitat, including man-made environments. Rodents can be arboreal, semi-aquatic, or fossorial.

Norway Lemming

The Norway Lemming, scientifically known as Lemmus lemmus, is a rodent inhabiting the Arctic tundras. Its coat, unlike that of other rodents, can be quite noticeable in appearance: gray with reddish-brown stripes or tawny and black. Other physical characteristics include short legs and stump of a tail as well as a round body and nose.

The shape of a Norway Lemming’s claws help it burrow into the snow-- a necessary action in the winter for protection as it does not hibernate. In the spring however, the lemming moves from the tundra to higher areas. Lemmings are known to reproduce at rapid rates, leading to aggressive population fluctuations.

Norway Lemmings have a height of 2.2”-2.6” (5.5-6.5 cm), body length between 5.1”-6.3” (13-16 cm), and an overall weight in the range of 2.5-4.6 oz (70-130 g). The tail length of a Norway Lemming is .4”-.75” (10-19 mm). Norway Lemmings have a typical lifespan of 1-2 years in the wild and 2-3 years in captivity.

Eastern Gray Squirrel

The Eastern Gray Squirrel (Sciurus carolinensis) is a tree squirrel that inhabits large areas of dense woodland ecosystems in the Eastern and Midwestern United States; the species construct dens in large tree branches within the hollows.

They are scatter-hoarders, and food is stored in numerous small caches for later recovery; these stashes are made up of a range of foods like tree bark, tree buds, berries, and many types of seeds and acorns. Physically, the Eastern Gray Squirrel has mostly gray fur, but there are brown variations. The underside is white, and it has a large and bushy tail.

Eastern Gray Squirrels have a height of 4.3”-5.5” (11-14 cm), body length between 8”-11” (20-28 cm), and an overall weight in the range of .9-1.3 lb (400-600 g). The tail length of an Eastern Gray Squirrel is 7.5”-9.8” (19-25 cm). Eastern Gray Squirrels have a typical lifespan of 6-12 years in the wild and up to 20 years in captivity.

Roborovski Dwarf Hamster

The Roborovski Dwarf Hamster, whose scientific name is Phodopus roborovskii, is a small species of hamster measuring two to three inches long on average, with a portly body, short legs, and short tail. Dwarf Hamsters are omnivores with specific diets as a result of the region they inhabit and the season.

Due to its tiny size however, it will more often prey on insects rather than on smaller animals. The Roborovski Dwarf Hamster lives in burrows dug underground to protect itself, either occupying these shelters alone or in small groups depending on the species.

Roborovski Dwarf Hamsters have a height of 1.1”-1.9” (2.7-4.7 cm), body length between 2”-3” (4.5-7.6 cm), and an overall weight in the range of .7-1 oz (20-30 g). The tail length of a Roborovski Dwarf Hamster is .125” (3 mm). Roborovski Dwarf Hamsters have a typical lifespan of 2-3 years in the wild and 4-5 years in captivity.

Common Vole

The Common Vole (Microtus arvalis) is a small vole within the over 100 different species in the rodent genus of Microtus. Physically, the Common Vole has a stout body, blunt nose, tiny eyes and ears, and hairless tails. Although it can be mistaken for other rodents based on appearance, its behavior is what causes distinction.

The Vole will dig burrows underneath plants to gain access to its root systems, destroying the area and eating until the plants are dead. The presence of a number of Voles will become noticeable upon the destruction of a number of plants, although they play an important role in the disbursement of nutrients.

Common Voles have a height of 1.4”-2.2” (3.5-5.5 cm), body length between 3.1”-5.1” (8-13 cm), and an overall weight in the range of .7-1.4 oz (20-40 g). The tail length of a Common Vole is 1.2”-1.6” (3-4 cm). Common Voles have a typical lifespan of .5-1 year in the wild and 1-3 years in captivity.

Common Degu

The Common Degu (Octodon degus), or just degu, is a small, social rodent unique to the lowlands of Chile. Active and extremely social during the day unlike the nocturnal rat, the Common Degu lives in burrows underground dug out in large communities of up to 100 rather than individually.

It is physically characterized by yellowish-brown fur, round ears, thin tail, and figure eight-shaped cheek teeth-- the reason behind its scientific name. People are able to keep the Common Degu as a pet, but it is recommended to have more than one as they thrive in colonies.

Common Degus have a height of 5.1”-5.9” (13-15 cm), body length between 9.8”-12.2” (25-31 cm), and an overall weight in the range of 6-10.6 lb (170-300 g). The tail length of a Common Degu is 5”-6” (13-15 cm). Common Degus have a typical lifespan of 1-4 years in the wild and 5-9 years in captivity.
