They do not commit suicide: Lemmings

It is said, when overcrowding becomes an issue, they will run for the sea, throwing themselves off the cliffs for the good of the species. Lemmings can also explode.

Is it?

No, no, no! When the population becomes too dense, lemmings will seek pastures new – but they do not commit suicide and they do not explode.

Lemmings are a kind of short-tailed vole, a mouse-like rodent that favors tundra and open grasslands. A lemming is a small rodent usually found in or near the Arctic in tundra biomes. Lemmings are subnivean animals. They make up the subfamily Arvicolinae (also known as Microtinae) together with voles and muskrats, which forms part of the superfamily Muroidea, which also includes rats, mice, hamsters, and gerbils.

Lemmings weigh from 30 to 110 g (1 to 4 oz) and are about 7 to 15 cm (3 to 6 in) long. They generally have long, soft fur, and very short tails. They are herbivorous, feeding mostly on leaves and shoots, grasses, and sedges in particular, but also on roots and bulbs. At times, they will eat grubs and larvae. Like other rodents, their incisors grow continuously, allowing them to exist on much tougher forage than would otherwise be possible.

Lemmings do not hibernate through the harsh northern winter. They are masterful burrowers. They remain active, finding food by burrowing through the snow and using grasses clipped and stored in advance. They are solitary animals by nature, meeting only to mate and then going their separate ways, but like all rodents, they have a high reproductive rate and can breed rapidly when food is plentiful.

Lemmings have large population booms every three or four years. When the concentration of lemmings becomes too high in one area, a large group will set out in search of a new home. Like many other rodents, lemmings have periodic population booms and then disperse in all directions, seeking the food and shelter.

The Norway lemming and brown lemming are two of the few vertebrates which reproduce so quickly that their population fluctuations are chaotic, rather than following linear growth to a carrying capacity or regular oscillations. It is not known why lemming populations fluctuate with such great variance roughly every four years before numbers drop to near extinction. For many years, the population of lemmings was believed to change with the population cycle, but now some evidence suggests their predators’ populations, particularly those of the stoat, may be more closely involved in changing the lemming population.

Lemming behavior and appearance are markedly different from those of other rodents, which are inconspicuously colored and try to conceal themselves from their predators. Lemmings, by contrast, are conspicuously colored and behave aggressively towards predators and even human observers. The lemming defense system is thought to be based on warning display. They use their defense mechanism to attack their predators and humans.

In the below news article we can notice that these pretty looking creatures can be destructive:

When lemmings ATTACK: Aggressive rodents use multicolored fur and loud shrieks to warn predators to stay away

By Richard Gray for Mail Online Published:  6 February 2015

They may have a reputation for committing suicide, but it appears that lemmings actually have a powerful survival mechanism.

Biologists have found that the furry Scandinavian rodents use their multicolored fur and emit loud screams to scare away predators.

They say that the rodents employ a form of aposematism – the use of colors and other signals to warn that an animal is toxic or dangerous.

However, in the case of Norwegian lemmings, they back up the message from their yellow, brown and white fur and loud barking calls with some aggressive biting.
Unlike other rodents, the creatures are known to fight back against attackers with loud screams, lunges and biting their sharp teeth.

You can seek help from C Tech Corporation to get rid of menace cause by lemmings.

At C Tech Corporation we make use of Mother Nature’s gift of senses to these rodents in developing non- toxic & non- hazardous formulation!

RodrepelTM is a low-toxic, non-hazardous rodent aversive. RodrepelTM is a perfect blend of smart technology and green chemistry. This product acts through a series of highly developed intricate mechanism ensuring that the rodents are kept away from the application. The product is compliant with RoHS, RoHS 2, REACH and is FIFRA exempted. Our eco-friendly products do not kill the target species but only repel them.

The products are available in the form of a masterbatch which can be incorporated in pipes, films, cables etc. while manufacturing. This would result in the final cable or wire being rodent repellent. This would be an efficient way of deterring the rodents from chewing the cables and wires and thus negate the possibility of a short circuit.

While the RodrepelTM liquid concentrate can be mixed with the paints in a pre-determined ratio and applied on the interior and exterior of houses, concrete fences, kitchen and laundry areas, storage areas etc. to keep the pests away.

RodrepelTM lacquer can be coated over the applications which need protection. The lacquer can be applied to the wooden furniture, fences, kitchen trolleys, already installed wires and cables, pipes, metallic decors etc. The product is compatible with most of the surfaces like wood, metal, concrete, polymer, ceramic, etc.

The product triggers a fear response in rodents thus protecting the application. It causes severe temporary distress to the mucous membrane of the rodents due to which the pest stays away from the application. The product triggers an unpleasant reaction in case if the pest tries to gnaw away the application. After encountering the above-mentioned emotions, the animal instinctively perceives it with something it should stay away from and stores this information for future reference. The fact that certain rodents are repelled is mimicked by other rodents as well. Thus, the other rodents too stay away from the applications. The unpleasant experience is imprinted within the animal’s memory and passed on to its progeny.

Our products provide a safe and environmentally friendly solution to avoid rodents.
