To verify the presence of rats or mice in our environment is critical surveillance.

     For control of rats it is most important to inspect and verify the presence of rodents. Signs and most important indications are: nibbled objects, excrement and urine stains, odor, tracks, nests and excavations, queues and brands live or dead rats.

     When rats are visible in broad daylight or frequented by humans, we can be sure that there is a great plague that forces them to leave day to survive, since rats are nocturnal and crepuscular. To the tours they want to stick the corners of the walls to feel safe. Voles tend to follow the shortest route, even being seen uncovered.


Rats are very prolific animals, when one can be observed in the nest more than twenty.

     Various investigations in recent years have shown that rats are very intelligent animals and have a great sense of smell, sense that they have highly developed, with ability to select their foods avoiding prejudicial to him, can distinguish any ingredient in an elaborate meal, as sugar, salt, irritants and different flavors.

     So they are very suspicious of new foods, facing a probable toxic substance has a way of learning innate in them that allows them to associate the characteristics of a given food and its subsequent metabolic consequences, if you become ill through eating contaminated food created an aversion which lasted many months, in the pack sent to an individual dominated the colony to test the suspect food, depending on whether it lives or dies prove the rest of the pack.

    Man is capable of searching toxic and deceive inducing them to eat rats, but these draw their defense mechanism to avoid it. Therefore poisons are not very effective for rats, only acute lethal dose of poison, the disadvantage is to be eaten mostly by all individuals. The rat poison is very dangerous to humans, especially children, pets and other animals in the wildlife. Also the dead rats are a major health hazard to humans by poisoning produced water and the diseases they transmit. At other wildlife animals it presents the danger is when consumed.


Since ancient times the rats have moved all over the world thanks to navigation.

    In summary, the rat is an animal that adapts to any environment, in the world only the Antarctic, where the cold prevents them survive above has a highly developed genetic resistance to various poisons that are fatal in other animals is saved and is a vector , transmitter many diseases thereby becomes an unwanted companion man. It is emphasized that the rats represent a great polluting potential of food and general environment that can create allergic problems.
