Healthy rats typically avoid people and prefer to be active when buildings are quiet. However, when cornered, they will lunge and bite to defend themselves. The saliva of some species of rats carries hazardous diseases, such as leptospirosis and Hantavirus. In rare cases, rat bite victims may contract rat-bite fever.
They are filthy, destructive, can carry disease, and bite approximately 50,000 people each year. They can even destroy crops and property. So when they show up in your home, it's hard to stay calm.
How Do Rodents Get In? Rats and mice can crawl through very small spaces (under doors, into crevices, etc.)
The main concern with rat bites is that you will develop a specific type of bacterial infection known as rat-bite fever (RBF). Humans can contract this illness if an infected rat bites or scratches them. Petting or handling an infected animal can transmit the bacteria, as well.
Both rats and mice are good climbers and can climb vertical walls and "shimmy" up between walls and drain pipes. Rats are also excellent swimmers and have been known to enter premises through the water traps of the toilet bowl when infestations occur in the main sewerage system.
Bites from rodents are rare, but can happen if the rat or mouse feels threatened. They can also happen if the rodent is rabid. Mice are less likely to bite a person or animal than rats are. Rodents can transmit diseases with their saliva through their bites.
Rats are actually scared of humans. They will do anything in their power to avoid being around a living being larger than them. However, if a rat feels cornered, it may attack in an attempt to protect itself.
Since rats have been known to bite, this makes it even more frightening that they are also known to carry disease. Rat bites and scratches may result in disease such as lymphocytic choriomeningitis (LCMV), which is a viral infectious disease, salmonellosis, or even rat-bite fever.
Rats can acquire fear by observing conspecifics that express fear in the presence of conditioned fear stimuli. This process is called observational fear learning and is based on the social transmission of the demonstrator rat's emotion and the induction of an empathy-like or anxiety state in the observer.
Sprinkle scents they don't like
A great way to bring mice out of hiding and steer them in the direction you want them to go is to sprinkle potent scents they find particularly unpleasant. Mice don't like the smell of garlic, onions, cayenne pepper, cloves, ammonia and alcohol.
Inside, rats can be found hiding out in holes, cracks, and crevices; climbing up through drains in bathrooms and kitchens; behind cabinets; behind and under appliances; in air ducts and ventilation systems; in piles of clutter; in storage containers; in hollow walls; and in crawlspaces, attics, garages, and basements.
Food of Any Kind. Of course, rats are most attracted to food. A home with easy access to food of any kind, including scraps and crumbs, virtually asks rodents to invade your home. This is especially true during the winter because rats need to eat twice as much compared to the warmer seasons.
Any new or unexpected noise will frighten them and send them scurrying. However, once rodents get used to a sound, they will no longer fear it. This means that ultrasonic repellents can be effective at first, but if an area has plenty of food and provides shelter, the rats will have a great incentive to return.
Rats cannot tolerate smells such as ammonia, mothballs, peppermint oil, crushed cayenne pepper, and pepper spray due to their intensified sense of smell. Clean and uncluttered homes and yards scare rats due to the lack of food and places to hide, as well.
Rats are afraid of human activity, mostly because humans are so much larger than they are. Rats also fear predators such as hawks, eagles, and other birds of prey. Other animals that rats are afraid of include your cat as well as rat terriers and other dogs that hunt rodents.
Rats need a continuous source of food. If there is no food source then the rats will move on. Typically, there is no source of food in abandoned houses.
Yes, clean houses can get rats. And just like mice, rats are looking to see if your home can provide them with what they need, especially in the winter, regardless of how clean your house is.
Try Natural Deterrent Methods
Spread peppermint oil, cayenne pepper, black pepper, or cloves around the home's exterior to prevent the rats from entering the house in the first place.
Rats are exceptional climbers, undeniably. Also the little cousin of the rat, the mouse, can reach counter tops and tops of dressers. For that reason, it is safe to think that a rat can conveniently climb onto a bed. Additionally, a pet rat owner can personally say that a rat can get into a bed.
The reason for this sudden spike in rodent activities during the cold months is that mice and other rodents are scrambling to get inside homes for food and warmth. When they enter the home, the bedroom is one of the coziest places where they might find both amenities.
Being opportunists, rats will come out in the middle of the night, but most rats prefer to feed at dusk and again just before dawn. And because their teeth never stop growing, they are forever gnawing to trim their teeth!
