Rodent Control

Introduction

 

Generally the rodents are described as commensal, field, urban, domestic and wild on the basis of their relations with man. They belong to class mammalia, order Rodentia and family Muridae.


They are very sensitive to light, smell and noise. They posses remarkable capacity to adjust themselves to any environmental condition and run about seeking food during any part of the day or night. Rats always like to run next to wall or the runways.

 

Rodents not only feed on grains, but contaminate 20 times more than what they consume, with their urine, hairs, faces and even some times with their own dead bodies. The estimate of food grains losses by rodents in our country ranges from 2-4 million tons to 26 million tons every year.

 

There are more than 4000 species of mammals, of which about 1700 are rodents (Anderson & Knox 1967) of the rodents the family muridae contains the most species and of the genera the genus Rattus. However not all the 1700 rodents species are pests. About 150 species have been defined as a pest at some locality, to some crop at some time or another, but only 20 could be termed most important (Fall 1980). In connection with post harvest losses, the number of species occurring in and around human habitation drops to below ten.

 

Classification

 

Generally the rodents are described as commensal, field, urban, domestic and wild, on the basis of their relations with man.

 

Domestic Rodents - Living with man, examples are Rattus rattus and Mus musculus which nest and live actually in the houses with man.

Commensal Rodents- Living on man but not actually with man. Examples are Rattus noregicus and Rattus frugivorus. Their habit of preying on main food and on his waste products drives them to enter the human habits but they do not remain or nest there.

Field Rodents- Living on man but away from man. Example is Bandicota bengalersis.

Wild Rodents- living without man, example Merianes hurriane. They avoid man, feed on wild plants.

 

There can not be definite classification. A single species in the same area can be both wild and field as the field and commensal or again field and domestic. Bandicota bengalersis a typical field species shows a tendency to move into towns and become a true commensal rat, while black rat can be both domestic and field.

 

Nature and Extent of damages

 

Rodent damages both way i.e. quantitative and qualitative and varied so extensively to make out any realistic estimate of the losses. However it turns into millions of dollars per year all over the world. The damage caused by rodents can be broadly divided into the following categories-

Food losses–storage & field

Damage to articles of daily use

Damage to structures and installations

Public health hazards

 

Evaluating the Rodent Population

 

There are several indicators of the rodent population in or around the storage structure or the flourmills or processing plants-

Sound: Gnawing, Climbing noises in wall squeaks.

Droppings: Along walls, behind objects and near food supplies.

Burrows: Rat burrows are indicated by fresh digging along foundations, through floorboards, into wall spaces.

Runs: Look for dust free areas along walls and behind store materials.

Gnawing Marks: Look for wood chips around boards, bins, crates, fresh-gnawing marks will be pale in color.

Rodent odors: Persistent musk like odor is positive sign.

Smudge marks: There may be found or pipes or rafters,  where dirt and oil frame their fur leaves a greasy film.

Visual sighting: Day light sighting of mice is very common, Rats are seen in daylight only if populations are high. Quietly enter your barn at night wait the silence for five minutes and listen for the sound of rodent activity. Look around with a powerful flashlight, rat eyes will reflect the light.

Feeding locations: Rats will drag food scraps to the entrance of the burrows and other locations where they feed. Gnawed bones, food wrappers and other debris will be evident at there locations.

Urine:  The presence of urine odor is a clear indication of rat presence. Urine traces are fluorescent in ultraviolet light. Where available,

 

ultraviolet lamps can be used to look for the traces of rat urine.

 

Rodent - Chemical Control

 

The use of chemical compounds in controlling rodent pest is becoming more popular method now a day. The chemical Rodent Control method comprises of Fumigants, Tracking powders, Poisons, Chemosterilant, repellents and attractants. The poisons used for killing the rodents are known as Rodenticides, being poisonous are to be used carefully because of hazards to other animals of the surroundings.The chemical control can be undertaken as follows:

Burrow Fumigation (places of Breeding & hibernation).

Poison baiting (External and Internal)

   

Burrow Fumigation

 

The control of rodents by fumigation of burrows can be very effective but it may be expensive and dangerous one. It should be remembered through that the gas must have access to burrows if there are present in the building. Burrows should be open and the fumigant used must be heavier than air.

For effective burrow fumigation first off all, live burrows has to be traced, for this one has to conduct detailed survey in and out side the premises and live burrows can be traced out by flagging methods.

After live burrows are traced, fumigate the live burrows by putting the required quantity of fumigant in side the burrow. One Aluminium phosphide pellets of 0.6 gms is sufficient for a single burrow.

After putting or inserting the fumigant close the burrow firmly by placing glass pieces in side with the soil.

Have a regular watch over the burrows, which are fumigated for their re-opening.

Place one tablespoon of tracking powder in the reopened burrows and close them firmly.

The tracking powder is a contact as well as stomach poison and it also has longer residual effect when compared to that of celphos. This should by done by only trained operator.

 

Poison Baiting

 

Baiting is the effective and easy method of serving the poison to rodents by mixing it with most preferred food or the attractants. Before baiting one should remember that rats living in and around buildings are particularly suspicious of new object such as baits, bait station or traps. Therefor it may take some time before there are accepted by rats. For this reason it is important that once there objects are placed they are not touched or removed again. If a bait or trap has not been touched even after a week the rats are probably not nearby and it should be moved to another location.


As rule operators should be supplied only with Ready-to-use baits, firstly the mining can be dangerous to operator, secondly the wrong concentration of rodenticides may lead to bait-shyness. It is believed that Ready-to-use baits are costly but normally Ready-to-use baits do not increase the costs substantially.

Two types of rodenticides are available for bait preparation:

Acute Poisons

Chronic Poison

The company is executing rodent control treatment on most rational basis through a systematic study of Rats behavior, habits and habitat, bionomics, identification and nature of damage caused.
