I use a product qure rat hunter it is called.
He/she looks to my he/she has given me many results. It is a product that is special for the rodents, if you have dogs or other animals it doesn't kill them to you in the event of ingesting, clearing is better than they don't make it. the presentation bienen in envelopes or in pills, you will owe that it is very efficient. when the rodent dies he doesn't smell because what has the product makes that the animal becomes dehydrated yno he smells. ojale is served in something.

That of the cat believes it is the best thing apart from good cleaning. If not a good dog ratonero.

they Have to remember that to put animals unaware to those of your farm can carry you other parasitic or bacterial illnesses.
I continue recommending the product that I use although it doesn't seem them.
You don't invest a lot and truth the results in one week, undoubtedly if you have to clean well to be able to identify where they inhabit more the rodents.

it is certain that maybe he/she can bring you more enfermedaes of those than you have, I eat a Toxoplasmosis or others for example. But I believe that it is more important the presence of Leptospirosis for contact with rodents. In synthesis, maybe evaluate which the pro and the contras are, but up to now we didn't have any problem diagnosed by the presence of cats.

Like a humble opinion believes that the control of rodents makes part of a program of strict Bioseguridad in the farms porcicolas. For such a reason, the animal dómesticos is not advisable in an exploitation calls you poultry or porcícola. The cats and the dogs should not have any contact with our pigs.
He/she has been proven that in high infestaciones the cats cannot control them, the advisable thing is to implement a program of control of rodents with a specialized product (rodenticidas of chronic effect). This program is developed in three phases:
Inspection, treatment and pursuit. Ah, and the toilet frightens mouse.
Bioseguridad is the key of the success!.

Hello.
I agree with Carlos, the first thing it is the bioseguridad.
To carry out a control of rodents, it is necessary to begin to identify the problem that you have, due that the control is different among them. It is not same to control rats Norvergicus that the Rattus rattus.
You should know their biology and behavior.
I can send you information on their biology and behavior.
The effect of the natural predators in the rodents, doesn't justify its use, in fact, there are strong evidences that the number of predators depends on the quantity of predados in an area. On the other hand, the dogs and cats seem to be that they don't represent great danger for the rodents, on the contrary, it is common to find rodent living off the remains of food of these animals when the same ones sleep.
The mousetraps, which are easy to find in the market, are model old, and they have not suffered alterations practically from their invention. The use of mousetraps is advisable in places where the raticide use is contraindicated due to eventual high risks of accidents, or also in places where there are few rodents that to combat.
All raticide is toxic, some less than other, but it is important to never forget that it is products that should be pawed, employees and stored with much care. If it is used correctly of agreement with the technical recommendations contained in their rótulos, the raticides don't become more dangerous than the products that use to newspapers as the insecticides, detergents, etc.
I recommend you to use chemical raticides.
Then I will send you a control of rodents using powdered products. He/she remembers something, the control of the rodents it is long and honeroso.
Greetings.

Hello.
The domestic rodents, rats and mice, are very intelligent beings. Able to penetrate in almost all parts, tunnel the earth below the masonry constructions, they perforate the isolations of the cameras of cold, etc. Has very sharp claws that allow them to climb for very flat walls and to walk for pipes. They are good swimmers, being able to move for pipes of drainages even ending up surpassing the siphons with water. They live in the sewers, cellars or deposits and where it exists food or residuals of the same ones.
For that reason we make a lot of stress in the environment of a factory of sausages, the control of the efluentes and the insistent concern of maintaining appropriate hygienic conditions in the plant, a classification in the deposits of matters cousins, shops and other work areas.
In carefully maintained areas and with an appropriate control plan, they can surely stay these animals far from our factory. To be able to control them, it is indispensable to know their habits, preferences and customs. They have night habits for what the man cannot always see them, but rather he usually discovers his presence through the genius.
In their night exits looking for foods, these animals go leaving signs that we can observe to give us an idea of their size. The excrements can be observed that which, besides indicating their presence, it indicates their size and if they are fresh or not. It is also very common to find marks of their very identifiable step as, for example, stains of greasy dirts, with marks of paws and of bodies that adhere to the walls, beams, pipes, etc. for where they happen.
From the point of view of the public health, the rats are reason why portadoras of many illnesses that are transmitted to the man, a severe, methodical and insistent control plan it should exist in any factory of foods.
For an appropriate control it is required:
- to eradicate trash cans bordering to the factory
- to maintain the orderly environment and I clean
- not to leave foods or matters cousins outside of their storage place
- to use rodenticidas.
Stress has been made in this work in the first mentioned measures.
In relation to the employment of traps, it is necessary to say that their handling is something annoying. They should clean very well with hot water and the operator should use gloves during its preparation in order to eliminate the man's scents, overalls if this is smoking. Then an attractive bait is placed as it can be a piece of bacon, better if it is seasoned with, for example, paprika, anisette or cumin.
The employment of traps practically doesn't have influence on the population's of rodents density that can exist.
The most effective method in the control of rodents is the rodenticidas employment.
They are toxic substances that are in the market in form of liquid baits or solids that, placed strategically and with a plan of location rotation and of product, they get effective results.
An effective raticide should be mortal in small quantities to be able to incorporate to baits without being discovered, it should not inspire distrust to the rodents, it should not cause a violent and quick death for not waking up suspicion in the rodent survivors.
They exist in the market several types of raticides whose active principles kill in different ways.
Some produce interferences in the sanguine clotting of the rats, causing big internal and external hemorrhages that finish in a serious anemia that he/she brings the death like consequence.
Others produce an increase of the permeability of the capillary ones in the lung (small sanguine glasses). This causes a lung edema, with the consequent exit of liquids to the bronchuses and a decrease of the lung ventilation, with formation of foam that it takes to the asphyxia and the death.
Other more ones cause neurological and circulatory dysfunctions slowly, affecting the central nervous system and the heart.
In the practice, we have seen excellent results in factories, farms, bakeries for the control of rodents, by means of the combined actions of the classification of the environment and general measures of hygiene with the recruiting of experienced companies, with an appropriate methodology and the employment of baits raticides.
Greetings.

Hello.

THE BROADLY MOST EXISTENT SPECIES
Guarén or Pericote (Rattus Norvegicus)
The common, considered rat the most destructive mammal in the world. He/she inhabits places preferably with abundant water (banks of tidelands, sewers, channels, etc.) and in the exterior in burrows dug by her.

Black rat (Rattus rattus)
The black rat of the roofs or of ship, well-known as the transmisora of the feared bubonic fever. He/she is habitually in the high sectors of constructions (entretechos, galpones, trees etc.), being a very good climber.

Mouse or Laucha (Mus muscles)
The mouse tames, the rodent diner but broadly distributed. He/she inhabits closed places as pantries, warehouses and housings in general.

Pity, the pictures didn't come out.

Greetings.

Greetings, another time.
Among the species of vertebrates that have been acclimatized to the environment of the facilities, and to end up constituting a risk for the health and for the productive systems, they stand out the rats and mice that you/they live in narrow association with the man, of there their denomination of Domestic Rodents. They belong to the order Rodentia, family Muridae with the species: Mouse (Mus musculus), gray rat or of the sewers (Rattus norvegicus), and the black rat or roof rat (Rattus rattus).

Although emphasis won't be made in other vertebrates, if it is necessary to mention other species of risk for the industries: dogs, cats, certain types of birds (birds, marine birds, doves, etc.), bats that can end up generating nuisances and problems of diverse nature, as payees of illnesses and parasites, aesthetic, causing with excrements (where mushrooms and bacterias take place) damages to the foods, facilities, and putting in risk to the processes and nutritious products, situations that end up justifying their control.

GENERAL CHARACTERISTICS

As we have mentioned it, it is important to establish a program of control of rodents to have knowledge of the species, their biological characteristics, habits, etc.

The rats and mice belong to the family of the Múridos whose main biological features are:

•,Cuerpo generally covered with hair that moves periodically.

•,Piel with numerous glands (sebaceous, sudoríparas, mucous and mammary).

• & #61472,Cráneo with two occipital cóndilos (the skull is articulated this way in the first vertebra) therefore, the head is mobile.

•,Generalmente, has 7 cervical vertebras.

•,La line, when it exists, it is long.

• & lengthened nasal #61472,Región, mouth with teeth in both jaws and omnivorous nutritious customs.

• & #61472,Ojos with mobile lids, although they have little developed the sense of the view since they are of night habits.

•,Oídos with fleshy external pavilion that allows a good development of this sense.

• & #61472,Cuatro extremities each foot with 5 fingers that are adapted indistinctly to walk, to run, to climb, to dig or to swim. The fingers have horny fingernails or claws and often fleshy bearings.

•,Corazón with 4 separate cameras.

• & breathing #61472,Aparato formed by two lungs the diaphragm separates the cavity toráxica of the abdominal one.

• & even #61472,Doce of cranial nerves and very developed encéfalo, the same as the brain, what explains their wide learning capacity and training.

Stable corporal •,Temperatura.

•,El male has organ copulador and therefore he/she carries out internal fecundation.

• & #61472,Los eggs is tiny and they are retained in the uterus of the female. The fetus is developed in moon placenta that facilitates its nutrition and breathing. The young individuals are fed by the females by means of milk that you/they secrete through their mammary glands.

The senses of these species are well developed in general, highlighting especially, the following features:

• & #61472,VISTA: Their eyes are specialized to detect only movements. They can only detect forms and they don't recognize the colors.

•,Tacto: Very developed, the mustaches are the organs of the tact that habitually use to be guided in the displacements. The rats and mice can memorize their surroundings and to move in the darkness until finding their burrows.

•,Oído: Sharp, well developed and very useful in the event of danger.

• Smell: Sharp, it carries out an important function in the behavior of the rats and mice.

CHARACTERISTIC BIOLOGICAL OF RODENTS

There are many reasons, but the most important is that the rats and the mice represent a great danger constant for the human health:

• & #61472,Devoran foods.

•,Ensucian the foods with their excrements, he/she urinates, hair germs and patógenos.

•,Destruyen different packing materials.

•,Dañan the facilities because they gnaw wood, pipes, electric cables, etc.

• & #61472,Construyen their burrows in embankments, banks, etc. Destroying this type of works and structures.

• & #61472,Inquietan to the animal estabulados. The consequences are: decrease of the production milkmaid, of the production of eggs and loss of weight.

•,Transmiten to the man and the other animal illnesses for via direct.

• & #61472,Son also responsible insinuations of the transmission of illnesses through their specific ectoparásitos (for example, the transmission of the bubonic pest for the tropical flea of the rats).

•,Provocan hurt by bites and other lesions.

• & #61472,Con their rodent activity causes at level world damages for value of thousands of millions of pesos, but the losses for contamination they are even bigger.

•,Las rats destroys 33 million metric tons of foods a year.

•,Año after year the rats take as booty the 16 of the foods of the India.

• & #61472,Más of 200 organisms patógenos (virus, bacterias, molds, worms, arthropods, etc.) they associate with the rat.

•,Contaminan at least the triple of the food that you/they are able to consume.

The complexity of the behavior of the rodents on one hand and the serious damages that, on the other hand, they cause in the crops and in the material ensilado, as well as their condition of vectors of illnesses, it has met the man from antiquity to fight against these rodents. Nevertheless, to give with the appropriate desratizador and to apply it with success becomes difficult since the rodents have an instinctive aversion to that ignored, a sense of the very developed smell and a very refined palate.

METHODS AND TECHNICAL IN THE CONTROL OF RODENTS

The desratización has as objective the control of the rodents (rats and mice) inside of and outside of the facilities and it is based in the prevention, preventing that the rodents penetrate, live or proliferate in the local or facilities and we can synthesize this way these procedures:

DIRECT CONTROL

Chemical methods: repellent, baits, toxic, fumigantes, quimioesterilizantes, attractive.

Physical methods: traps, ultrasonidos and energy use.

Biological methods: bacterias, depredadores.

With the chemical method use of raticides is made, chemical compounds that blended with an attractive bait they settle in the area with the purpose of that the rodent locates and it consummates the bait, this way the access is avoided to the areas because it satisfies a nutritious necessity and in turn the control.

The compounds more recommended for the control of rodents they are the anticoagulants as the Racumín (comactetralyl) and the Rodilón (difethialone) and the general characteristics of this group are:

They produce the slowed death (3-5 days) after the ingestion of a raticide dose.

The rejection to the bait is not a problem because the poisoning symptoms are presented late after the ingestion of the bait, without signs of rejection are observed or it alarms.

They are effective to lower dose, and they are moderately toxics for the men and other animal species.

In the event of an intoxication you can control with the application of the antidote.

They act inhibiting the factors of the clotting and promoting the internal hemorrhages in the animal.

INDIRECT CONTROL

I manage of the environment: sanitary appropriate, practical constructions, controlled evacuation of the residuals and garbages.

Practical cultural: control of molasses, elimination of garbages, control of burrows, access control with blockades to the entrances of facilities and local, to impede the access to sources of water.
