Rats are undesirable creatures that have been the symbol of death, pestilence, and disease. Rats can cause billions of dollars in damage and can start fires, spread serious diseases, and multiply rapidly to infest homes, according to the article Top Ten Fascinating Facts About Rats. Additionally, the inundation of rats in a home can cause panic and mass hysteria, with residents calling pest control companies and law enforcement as soon as they see a rat, as expressed by John Davidson in Floods See Rat Population Explosion . The trouble that the rats cause has been an issue for a very long time. The flood of rats that invade a home is believed to be caused by an increases in food sources near populated areas, and decreases in predators and dry …show more content…
nesting areas, which cause the rats to migrate to urban shelters, and now homeowners, pest control companies, and law enforcement are attempting to do everything in their power to rid their homes of them. Rodents prefer dry areas for nesting, large food supplies, and few predators. When the rats nesting areas are disturbed, or when there is an abundant food supply in a certain area, then the rats will flood to the desirable location and take root, feeding and multiplying with horrifying speed. In the case of a flood, the rats will leave their homes in the sewers and soon move into residential areas, where there is a steady source of food and secure nesting spots. For example, in Floods See Rat Population Explosion, "Rats like to have somewhere that's dry and sheltered to nest. They're not bothered by water but they don't want to live in it 24 hours a day.”The relative safety of the residential building is taken advantage of by the rats whenever their normal nesting spots become compromised. Another situation that causes an increase in rodent population is a sudden increase of food in a certain area. For example, in India, the residents suffer from large swarms of rats destroying crops. “This explosion in the rodent population, leading to swarms of hungry pests, is caused by a glut in the food supply, namely bamboo seeds,” according to the article Attack of the Rats. The availability of the bamboo seeds is readily exploited by the rtas, and they also find additional food sources in the neighboring areas, hence the destroyed crops. The rat infestations can be caused by a variety of different factors, but in general, rats will go to an area that is desirable and meets all of the requirements. The reason for rat infestations vary from place to place, but once they enter a home, major problem begin to emerge.The proliferous nature of the rats soon make them a major problem for the homes they infest by biting electrical cords and contaminating food, as expressed by Jerry Falke and Bruce Leland in Rats! Rodent populations proliferate in some parts of Texas. Furthermore, “Around 60% of the rodents carry Weil's disease...which causes flu-like symptoms or in more serious cases kidney and heart failure,” according to John Davidson, in Floods See Rat Population Explosion. The risk of contracting a disease from the rats has become an issue, and makes the pestilence of rats an even larger problem. The risk of starting fires through chewed electrical cords is also realistic, and now homeowners are taking extra steps to rid their houses of these rodents. Many methods have been employed to rid houses of the undesirable rat, and only a certain number prove to be effective, due to the fact that all methods have advantages and disadvantages.
For example, when using rat poison, it may be effective in killing the vermin, but it can also cause unwanted harm to children and pets, and if a rat dies in the walls, the resident will be unable to retrieve the body and soon the stench of rot will fill the household, as shown in Top Ten Fascinating Facts About Rats. One method of killing rats involves terriers, which are dogs that have been specially bred for the purpose of killing vermin. It was recommended by Rachel Bauer, who asserted that “as a possible means of control, based on their situation, some people consider getting a cat or dog that has been bred or trained to be a “mouser,”” in Rats! Rodent populations proliferate in some parts of Texas. Other methods, such as gassing, traps, and baiting are also used. The rat infestations are very difficult to prevent, due to the fact that rats’ teeth are incredibly strong, according to Top Ten Fascinating Facts About Rats, so all methods that have been proven to be effective are recommended for the use of clearing the house of
rodents.\ To conclude, rats are creatures that can destroy wiring, spread disease, and damage homes. Many different factors cause increases in rat population, but some of the most common are increases in food, disturbances of nesting sites, and decreases in predators. Rats will chew through material in order to enter the home, and once they have entered, they will multiply rapidly and soon become a major complication. Several techniques for ridding houses of rats have been employed, including the use of terriers, cats, traps, and poisons, but all methods have advantages and disadvantages. Rat infestations are feared by every homeowner, and it is best to be prepared and ready for unwelcome guests at all times.
Pit bulls, the most dangerous dog to ever live. People like to train Pit Bulls to fight other dogs until they are either hurt or dead. The owners that train the dogs are usually the ones that make the dog turn out to be vicious and dangerous. “Each year, 1.2 million dogs are euthanized, approximately 40% of whom are Pit Bulls”(Moore). Pit Bulls don’t know better to understand which is right from wrong since they’re being raised up to fight and protect. Pit Bulls aren’t good family dogs due to the power of their strength and that they could attack at any moment.
The Purpose of our Mouse Trap Car project was to find a way to use what we have learned from Physics and Newton's laws to make a mousetrap powered car. We had a goal to create a car out of material you already had that goes 3 or more meters across the room. We had to find a way to get all the parts and build it with nothing but glue and tape and whatever you had in you house. This challenged involved many aspects such as building/engineering, time management, focus, and most importantly science.
Analysis: As the story progresses, the narrator describes the dream he has been having since entering the house. While this nightmare appears to be an effect of living in the cursed house, the dream turns out to be prophetic. In his dream, the narrator sees a man control rats and kill a man with whom he is angry. This course of action ends up being identical
It is the self-proclaimed savior of the world , which , when the slaughter is over, " mutually come in " into the enclosure. Some intend to poison the rats by the smallest possible pain to maintain a balance within nature , others are committed to the rats . Rats are ultimately animals. And who should decide whether a bird or a rat may live ? Who gives people the right to shoot sheep, their overpopulation causes they eat an island bald?
Bigger's first encounter with a rat foreshadows what will happen to him later on in the story and explains his reaction to danger. ?The rat automatically becomes a natural enemy and an invader the moment it is discovered in Bigger's apartment? (Hakutani 41). Bigger's family is instantly afraid of the rat and demands its destruction. Buddy blocks the entrance to the rat's home, leaving the rat trapped in the room with no escape. Finally, the rat becomes frenzied and resorts to violence to protect itself from Bigger and Buddy. "The rat squeaked and turned and ran in a narrow circle, looking for a place to hide; it leaped again past Bigger and scurried on dry rasping feet to one side of the box and then to the other, searching for the hole. Then it turned and reared upon its hind legs" (Wright 4). Initially, the rat is shown as helpless, with no intent to hurt Bigger. The rat's fight for its survival becomes so desperate, however, that it leaps at Bigger's pant leg in an attempt to protect itself.
Multiple circumstances within the cities, families, and organizations of societies contributed to the rapid spread of the plague. Rats, ticks and other rodents or insects where one of the reason the plague spread throughout the world and most of Europe. The ticks and fleas where infected with the disease and they bit the rats and other rodents, which infected them with the disease. The ticks and fleas also bit other rodents, livestock and even the attached themselves to humans and transferred the disease to them. The rats or other rodents ran throughout the place they where bit by the tick. Some of the rodents began to go into ship yards and trains. They bread with other rats and begin to produce offspring which created an even bigger problem. The rodents got onto the ships and where transported around the world, along with the now infected materials on board. The rats would drop their feces around the ship and even on the drinking water and food. When the ships docked at ship yards around the world the rats got off and ran around the new country they now belonged to. Some of the supplies that where taken off of the ship included but was not limited to, liquids, foods and livestock. These supplies where shipped around the world and contributed greatly to the spread of the disease.
The interesting connection that humans have to rats is the grouping they exhibit. The leader-rats seem to take their own groups and then the average to below average rats gather together. Human aristocrats and wealthier people, like the leader rats, tend to live in suburbs and live in quieter, nicer places. The other people, like the average to below average rats, seemed to live in smaller apartments and much more crowded, less healthy areas like the slums.
The Black Death is now known to be spread by a flea. However, this flea was not the cause as it was the bacterium which lay in the stomach of the flea. This bacterium’s scientific name is Yersinia pestis. The main host of the flea is a rat, scientifically called Rattus rattus. Humans caught the disease because when the rats bred rapidly, it would lead to a population invasion. When the rat died, the flea would have to find another warm-blooded host to feed on, and next to them are humans. The flea bites the human and infects them. The unhygienic living conditions in the Middle Ages led to a faster spread of the disease, as a result creating a better environment for rats to live in. The lack of knowledge in the fourteenth century led to even worse remedies.
How do you get this disease? When a rat is infected, the flea bites the rat then the

At first in the Mill, the rats only judged Hall and watched him with cold eyes. His time in the picking room is spent antagonizing the rats and they seem benevolent at first. They don’t reciprocate that same violence as Hall displays,they just scatter and the watch him once he gets to work. This is shown when the narrator says, “ And after a while, the rats came out and sat atop the bags at the back of the long room watching him with their unblinking black eyes. They looked like a jury” (2). It indicates that their danger is not something that Hall is worried about,the rats just freak him out to an extent. Yet as the men venture into the first level of the basement, the rats start to approach them and attack, becoming more hostile in their presence. Their antics work to an extent, some men uit and refuse to work with the dangerous conditions the rats present, but for the most part, the expedition of furniture, dirt, and rats continues. This is exemplified in this line. “One of them had sat up on their hind legs like a squirrel until Hall got in kicking distance, and then it had launched itself at hids boot, biting the leather” (4). They become more aggressive by presence only, not only incitation of violence. The increasing aggression only

However it only works if people actually have their pets spayed or neutered. In Sochi Russia during the last Olympic Games, there were stray dogs found around the entire city. The dog population was out of control. They even had adoption stations in the city so tourist could adopt pets, and take them home to be their own pets. A local pest control company has a contract to scoop up and kill Sochi 's strays, in part to avoid any embarrassing appearances by dogs during competition. The International Olympic Committee is trying to paint a less gruesome image of the dogs ' fate(“Opposing Viewpoints in Context - Document”). Scooping up dogs and euthanizing them happens all over the world, I commend those who adopted dogs from their wicked
Animal Cruelty has many forms, many reasons and most importantly many victims. It is a growing problem in today’s society. Many people may wonder why people abuse animals. The thought is simple, however the answer is a little more complex, there are three main types of animal cruelty. The three reasons are as follows: unintentional, intentional, and cruel intentions. I will discuss each one in more detail.
