RAT CONTROL BY BEHAVIOUR
The behaviour of rat and mice is different. Rat behaviour can be understood by following categories
DRINKING BEHAVIOUR FOR RAT CONTROL
Rat species consume up to 60 ml of water daily depending upon their body weight. The consumption of water depends upon temperature, activity, age and food source. Rat drinks water either directly by their tongue or making feet like a cup. If they are eating fruits, vegetables, insects or worms they will need less water. Due to availability of water in the sewers, drains and along banks of watercourses rats establish their population.
NOCTURNAL OR ACTIVITY BEHAVIOUR FOR RAT CONTROL
Most of the people think rats are active at night time. This is because their principal enemies are relatively not active at that time. Rats are mostly active within one hour of sunset and before dawn. The activity of rat may also be seen at day time depending upon availability of food, human activity and competition for food.
FEEDING BEHAVIOUR FOR RAT CONTROL
Rats are omnivores, this means they eat both vegetables and meat.They can consume insects, vegetables, and various types of grains. Rats consume food about 10%of body weight. This is one of the reasons why rats have been so incredibly successful as a species. But being an omnivore also means that an individual has a lot of choices about what to eat, and this poses great risks, the wrong choice could be fatal.
• Before birth:
In utero, fetal rats detect food particles that come from their mother’s diet and cross the placental barrier. Shortly after birth, newborn rats respond positively to these foods. Therefore, they start learning about what to eat from their mother before they’re even born.
Nursing rats receive information about their mother’s diet through her milk. They prefer the foods she ate during lactation.
When young rats are weaning and eating solid foods for the first time, they use adult rats as guides. They forage where the adults are foraging. Once they enter weaning stage they learn which food is good and which one is dangerous by following the older rats
when rats forage on their own, their food choices are influenced by social interactions that may take place far away from foraging sites. They smell foods on the fur, whiskers and especially the breath of other rats and strongly prefer the foods those rats had previously eaten.
Rats are very neophobic when it comes to food .The rats will not respond to new food if there is good supply of food already available, that’s why some time they respond to rodenticides. When the rat population is high and there is less availability of food source, they will not avoid the new food and will respond to the rodenticide. Rats can also carry food material back to their nest. Rats can hold the food in their feet.
When rats infest a home, they can use various things as a food source. Pet food is a common reason for rat infestations. Be sure to properly secure pet food, and quickly clean up any food that is not eaten by pets. Rats are able to chew through cardboard and thin plastic, so be sure to store grains in cans or rat-proof plastic .Periodic sweeping and vacuuming can remove dropped crumbs and other sources of food.The dropping color of the rat is also an indicator of what kind of food or rodenticide they are eating.
MOVING BEHAVIOUR FOR RAT CONTROL
The rat move from one area to another , from one building to another if there is a change in their area due to massive clean-up or construction is going on. They will not leave their area if they have good supply of food, water and shelter is available to them. The average range for food is 8 to 30 meter.
BURROWS BEHAVIOUR FOR RAT CONTROL
As every living want to protect him and young ones from predators, so they need some kind of shelter. The rat shelter could be found in the form of burrows in ground or in trees or building voids or in sewer line, inside or under the insulation in attic or crawl space areas. The rat burrows are 2 to 3 inches in diameters. The rat use the front feet to dig the burrows .they use their belly to shoves the loose soil out of the burrows. They push the loose soil with their hind feet with powerful strokes. The rat nest is inside the burrows and may be make of straws, cardboard, paper, leaves and insulation of attic or crawl space and inside the wall .most of the time the nest is located near the source of food. The rat nest in the sewers in wall voids of sewers and they use the sewers as guideline or highway.
