Rat Mice are always under constant threat of attack by other animals including humans. they are the among the major prey species on the earth planet. In order to survive they have developed several anti-predator strategies and their senses play an important role in this function.
SENSES OF DEFENCE
VISION (RAT MICE)
The vision of rodent is not poor that’s why they are adopted to night. they can distinguish between different shapes . they are color blind so the color of object like poison, traps or bait station does not matter to them.
SENSE OF TOUCH (RAT MICE)
Because of poor vision of rodent(RAT MICE) their sense of smell and touch is very well-developed. the fur of rodents are equipped with sensory nerves at their bases. these hairs are located at on the face ,head ,legs , belly , and other areas of body.these hairs help rodents to avoid dangerous surfaces.Due to this behaviour rat and mice travel along the walls . That is why trapping and baiting stations give good result when placed along the base board areas.
SENSE OF SMELL (RAT MICE)
The sense of smell helps the rodents to find out where is the food available. Rodents like other insects also secrete pheromones in dropping. which help them to find out the safe feeding sites ,finding other species of rodents and reproduction .The rodents dropping are some time used as bait on traps to catch them in traps.
SENSE OF HEARING (RAT MICE)
This sense is very well-developed in rodents . due to this sense they can hear both sonic and ultrasonic sound.if there is strange sound in their surrounding they will respond very quickly and will hide to avoid the danger. but once they get used to that sound they will not respond.
SENSE OF TASTE (RAT MICE)
Rodent can detect whether food contains or contaminated with chemicals. although their this sense is not very well-developed and is about 1 part per million .when the rodent bait is formulated this factor is very well monitored.
