10.Most Dangerous Animals Lurking In Your Backyard
Most people who live in the United States know that they probably don’t have the most dangerous animals around. Unlike Africa, Asia, South America, and Australia, there just aren’t that many large beasts that pose a danger to humans.
Of course, there are some big critters to be concerned with, but most often, the smaller the animal, the deadlier its bite. The following critters may be lurking in your backyard even as you read this, so beware the deadly bite, sting, or mauling from these deadly beasts.
10.Western Diamondback Rattlesnake Crotalius Atrox
Most people who live in Americ never see a snake for their entire lives, except maybe at the Zoo or Wildlife World Zoo. If you are unfortunate enough to be bitten by a snake, don't panic. Snake bites rarely result in fatalities, particularly if you know how to react. However, if you are bitten by a venomous snake, you must seek professional medical help immediately.
There are many varieties of snakes in the America, some of which are venomous and some which are not. The most venomous snakes that are the most dangerous to your health are the Western Diamondback Rattlesnake and the Arizona Coral Snake (also known as the Sonoran Coralsnake). The venom from a Mojave Rattlesnake can affect your nervous system. Baby rattlesnakes are dangerous because they tend to try to release as much venom as they can to protect themselves.
When a Snake Bites:
- Go to a hospital immediately.
- DO NOT use ice to cool the bite.
- DO NOT cut open the wound and try to suck out the venom.
- DO NOT use a tourniquet. This will cut off blood flow and the limb may be lost.
- DO NOT drink alcohol.
- DO NOT try to catch the snake. It just wastes time.
- Look for symptoms. If the area of the bite begins to swell and change color, the snake was probably poisonous.
- Keep the bitten area still. Don't tie the limb tightly to anything—you don't want to reduce blood flow.
9. Rabies Virus - Cute And Cuddly Mammals
Not all deadly organisms are deadly all on their own. The rabies virus is one of the deadliest neurotropic viruses on the planet, and a bite from an infected carrier resulting in transmission is nearly 100-percent fatal if left untreated.
In North America, it is most commonly found in wild animals like raccoons, bats, coyotes, rabbits, opossums, squirrels, skunks, wolves, foxes, cats, and dogs. Symptoms are not immediately present in many animals, so a bite from any of the above listed animals should be treated as a possible rabies transmission. For humans, this can be a painful and disturbingly inconvenient problem due to the nature of medical treatment for the virus.
Signs of Rabies in Dogs & Cats
The clinical signs of rabies may vary considerably. Initially animals may show changes in behavior such as nervousness and anxiety. This is referred to as the prodromal stage of the disease, which may last from two to three days.
This quickly progresses to irritability, photophobia (fear of light), biting, snapping, in-coordination and seizures. This is referred to as the furious form of rabies.
Some animals show signs of weakness, in-coordination and paralysis which also affect the muscles used for swallowing. This is known as the dumb form of rabies.
Rabid animals may exhibit one or more of the following signs:
- A change in your pet’s attitude
- Behavioral changes
- Inability to swallow
- A change in the tone of a dog’s bark
- Excessive salivation
- Wild animals may be unusually friendly
Once clinical signs of rabies have developed, death is inevitable as no cure exists.
8. American Alligator Alligator Mississippiensis
Alligator attacks are very rare, even in Florida where there are plenty of gators and people. Perhaps the best way to survive is to avoid attack in the first place.
Take special care in places that are known to be home to these reptiles; this means definitely don’t swim and also avoid the water’s edge – alligators are ambush hunters and can lurk, unseen, just waiting for something or someone to come along.
Time of day is also a factor in alligator attacks with dawn and dusk being prime times to avoid.
If in the unlikely event you do get attacked you need to make life as difficult as possible for the gator. They’re after an easy meal so anything to prevent this will go in your favor. Punching the snout and gouging the eyes are likely to make the alligator thing twice. It may also make the gator adjust its grip at which point you may have an opportunity to make your escape.
On the plus side the odds are firmly on your side as the vast majority of alligator attacks do not result in serious injury and very few indeed are fatal.
Alligator attack statistics
Obviously the alligator is in a different league to these giant crocs but the statistics don’t show the whole picture. Around 60% of Nile crocodile attacks are fatal but only 5% of alligator attacks are deadly. Ten years ago there were an average of around 11 alligator attacks in Florida each year but this number has been slowly creeping upwards. In fact over recent years there has been an average of one fatality a year.
7.Black Widow Spider Latrodectus
The female of the species carries a venom 15 times more toxic than the prairie rattlesnake, making it the most venomous spider in North America. A black widow’s bite carries with it a latrotoxin, which has the nasty effect of inducing severe muscle pain and muscle spasms.
Most people who are bitten by a black widow spider do not die but do live in fairly intense pain from the bite for up to a week. When children are bitten, they are much more susceptible to dying from the venom so they should be treated at a hospital immediately.
What Are the Symptoms of a Black Widow Spider Bite?
The black widow spider produces a protein venom that affects the victim's nervous system. This neurotoxic protein is one of the most potent venoms secreted by an animal. Some people are slightly affected by the venom, but others may have a severe response. The first symptom is acute pain at the site of the bite, although there may only be a minimal local reaction. Symptoms usually start within 20 minutes to one hour after the bite.
- Local pain may be followed by localized or generalized severe muscle cramps,abdominal pain, weakness, and tremor.
- Large muscle groups (such as the shoulder or back muscles) are often affected, resulting in considerable pain. In severe cases, nausea, vomiting, fainting, dizziness, chest pain, and respiratory difficulties may follow.
- The severity of the reaction depends on the age and physical condition of the person bitten. Children and the elderly are more seriously affected than young adults.
- In some cases, abdominal pain may mimic such conditions as appendicitis or gallbladder problems. Chest pain may be mistaken for a heart attack.
- Blood pressure and heart rate may be elevated. The elevation of blood pressure can lead to one of the most severe complications.
- People rarely die from a black widow's bite. Life-threatening reactions are generally seen only in small children and the elderly.
6.Coral Snake Calliophis, Hemibungarus
Have you ever heard the rhyme, “Red and yellow, kill a fellow; red and black, friend of Jack” and wondered what it was referring to? The fearsome creature that rhyme was written for is none other than the coral snake, which is one of the deadliest snakes in the world.
Their venom is an extremely powerful neurotoxin that paralyzes the breathing muscles. Since you need those muscles to . . . you know, breathe, your chances of surviving without an anti-venom are pretty much nil.
If you are bitten by a venomous snake, call 911 or your local emergency number immediately, especially if the area changes color, begins to swell or is painful. Many emergency rooms stock antivenom drugs, which may help you.
If possible, take these steps while waiting for medical help:
- Remain calm and move beyond the snake's striking distance.
- Remove jewelry and tight clothing before you start to swell.
- Position yourself, if possible, so that the bite is at or below the level of your heart.
- Clean the wound, but don't flush it with water. Cover it with a clean, dry dressing.
- Don't use a tourniquet or apply ice.
- Don't cut the wound or attempt to remove the venom.
- Don't drink caffeine or alcohol, which could speed your body's absorption of venom.
- Don't try to capture the snake. Try to remember its color and shape so that you can describe it, which will help in your treatment.
- Pain is felt at the region bitten by the snake.
- Two puncture wounds can be seen at the site of the snake bite.
- Swelling and redness is seen around the puncture wounds caused by snake bite.
- Patient bitten by a snake is likely to experience difficulty in breathing.
- Nausea and vomiting occurs.
- The vision becomes blurry.
- Patient salivates and sweats more.
- Patient experiences numbness in the face and limbs.

5.Arizona Hairy Scorpion Hadrurus Arizonensis
Sometimes referred to as your nightmare come to life, these nasty buggers can grow up to 5.5 inches long (14 centimeters), pack two lobster-like claws, and have a ferocious sting. In most people, a scorpion sting is not lethal.
This is due to its venom being comparable to a honeybee sting, which is painful but rarely fatal.
The problem with a scorpion sting is that many people who happen to be allergic to its venom don’t realize it—that is until they are stung by one. If a person has an allergy to these little guys, they will usually begin to have difficulty breathing, which can be fatal if left untreated.
The venom of the deathstalker scorpion produces a number of severe symptoms with death as a possible end result.
The venom of a scorpion contains a variety of different chemicals, including both neurotoxins and enzymes that penetrate the skin and other tissues.
Most people who are stung by a scorpion will feel a sharp, burning pain not unlike a bee or wasp sting, or will feel like an electric shock. The initial sting can be quite painful, but for most people the discomfort will subside within an hour.
After the sting, there may be burning or numbness at the location of the tail strike. Some people may experience numbness beyond the sting site, seizures, difficulty breathing, blurred vision, or other severe symptoms. If any of these symptoms occur, you should get immediate medical attention as these are symptoms of anaphylactic shock.
- Increased heart rate
- High blood pressure
- Increased fluid secretion into the lungs and bronchioles
IF YOU SEE SCORPIONS IN YOUR HOME
Scorpions have been known to enter homes in order to escape the heat of the desert sun. In order to prevent these occurrences, cracks in walls and foundations should be sealed, ensuring that small scorpions cannot enter. Homes should also be kept clean in order to prevent incidental insects that scorpions may eat, such as ants and cockroaches. Items such as boxes that can serve as hiding places for scorpions should be removed.
If one or two scorpions are seen inside a home in a scorpion-prone area, it may not be a sign of a problem. Individual scorpions can be prevented by ensuring that home entry points are sealed and that items such as clothing are scorpion-free before entering a house. If multiple scorpions are seen in a short period of time it is a likely sign of infestation and a licensed pest-control professional should be called.
4.Brown Recluse Spider Loxosceles Reclusa
These nightmares share something in common with rattlesnakes because their venom does pretty much the same thing. The necrosis brought on by these evil arachnids can cause severe disfigurement, amputation, and even death, though this is rare. Most bites result in horribly disfiguring scars and damaged tissue can, and often does, become gangrenous.
Brown recluse spiders are capable of biting when disturbed or threatened. This may occur when a person unknowingly wears an infested piece of clothing or rolls over in his or her sleep. Similarly, brown recluses are known to build their webs in boxes and beneath old furniture; reaching into these areas may result in a bite.
Reactions to the brown recluse spider bite are variable. Depending on the bite location and amount of venom injected, reactions run the gamut from mild skin irritation to skin lesions. Most bites heal themselves and do not result in lasting tissue damage.
These bites are not painful at first and often go unnoticed until the first side effects appear. Symptoms do not usually manifest for a few hours after the bite. After reddening and swelling, a blister may appear at the bite site. Victims of brown recluse spider bites can experience fever, convulsions, itching, nausea and muscle pain.
In extreme cases, brown recluse spider bites may result in necrosis, or the death of living cells. In this case, painful open wounds appear and do not heal quickly. Wounds will appear purple and black at this time. If left untreated, necrotic and ulcerous wounds can expand to affect both superficial and deep tissues. Deep scarring can occur in the wake of such brown recluse spider bite symptoms, and skin grafting is sometimes utilized to cosmetically treat scarring.
3.Honey Bee Apis
In the United States, the honey bee is classified as the deadliest non-human animal there is, resulting in an average of 100 deaths each year.
A person with the allergy can die within 10 minutes of getting stung and will show signs such as swelling of the face, throat, and mouth, their pulse will become rapid, and their blood pressure will plummet. Fortunately, a shot from an epinephrine pen (an EpiPen) will save a person’s life, so people who know they have the allergy tend to carry them wherever they go.
Honey bee stings are known to be very painful, but the symptoms that result from a sting vary, depending on the amount of poison that has entered the immune system of the victim. The initial pain eventually fades, but only after a period of swelling and itching. Some individuals may also experience visible signs, including redness of the skin around the sting. Although the honey bee sting is not commonly hazardous, some people may be allergic to the bee’s venom and will experience such severe side effects as nausea, fainting and, in extreme cases, death.
The numbers of stings also plays a role in the effects. As the number of stings increases, the severity of reaction also increases and can be lethal to anyone if stung too many times. If a person is stung or has medical concerns related to honey bees, they should seek a medical professional.
2.Rats And Other Rodents
Millions of homes in the United States have un welcomed guests in the form of rats and other rodents. And while the presence of these pests can affect the emotional well being of an individual or family, the health risks of having an unchecked rodent population in a home is far more dangerous than one might originally think.
Rats and rodents are known to be carriers of several types of diseases that can lead to serious illness and in some cases, even death.
To properly understand the dangers of rodents in the home, one must understand the basics of how disease can be spread.
Transmission of diseases usually occurs through several routes:
- Exposure to (handling of, ingesting of, and airborne particles from) infected rodent waste including: feces, urine, saliva, and nesting material.
- Bites from infected rodent or insect.
- Handling of infected rodents or insects – some viruses can transfer from skin to skin contact with no bite or scratch mark necessary.
The following is a list of diseases spread by rats, rodents and insects that feed or travel on these rodents like: fleas, ticks or mites.
Most commonly found in the white-footed mouse, cotton rat and rice rat, the Hantavirus is a potentially life-threatening disease that currently has no specific treatment, cure or vaccine.
Symptoms include: fever, fatigue, muscle aches (generally in hips, backs and thighs) and may include, diarrhea abdominal pain, nausea and vomiting.
- LYMPHOCYTIC CHORIOMENINGITIS VIRUS (LCMV)
Lymphocytic choriomeningitis virus, or LCMV, most popular host is the common house mouse. LCMV usually occurs in two stages. The first stage includes symptoms such as nausea, vomiting, headache, muscle aches and lack of appetite. The second stage is primarily more neurological in nature including the occurrence of: meningitis, encephalitis, or meningoencephalitis.
Yes, you read that right. The same plague that killed millions of people during the Middle Ages could be creeping around your floor boards and behind your walls. The most basic form of plague may be as close as one infected flea bite away. Of the different types of plague (there are several: Bubonic, Septicemic, Pneumonic) all are caused by the same bacterium: Yersinia pestis. The different types are classified by which level of the body the plague has reached: the immune system, the blood system and the lungs. Symptoms are dependent on the type. Prompt medical treatment through antibiotics is necessary to treat illness and possible death.
Some rodents carry the salmonella bacteria in their digestive tract, (who knew?) making any contact with rodent waste, especially the consumption of contaminated food, a potential risk to contract salmonella.
Symptoms include: chills, fever, abdominal cramps, nausea, vomiting, and diarrhea.
- RAT BITE FEVER
No, this is not the latest dance craze. As the name suggests, Rat Bite Fever is spread when a person has been bitten by a rodent who is infected, has handled an infected rodent (even when no bite or scratch occurs) or has consumed the bacteria in some form.
Symptoms include: fever, skin rash, headaches, vomiting, rash and muscle pain.
Caused by the bacterium Francisella tularenis, Tularemia is often found in rodents, rabbits and hares who are especially prone. Tularemia is most commonly transferred to humans by an infected tick or deer fly bite, or by handling of an animal that is infected. Reported in almost every state in America, Tularemia can be life a threatening illness, though most cases can be treated with the use of antibiotics.
Most common symptom:
- This is a normal reaction from the bite since flesh has been damaged by the rat’s teeth. Part of it is removed or penetrated and your body needs to receive a signal that something is wrong. Do not do any complex treatment, just make sure the wound is disinfected and try to find a medical help as fast as possible
- If streptobacillus bacteria is transmitted on a human being after the bite, symptoms like fever and vomiting may occur because of streptobacillus moniliformis infection. Such complaints are very likely to appear after the wound has healed and up to 10 days have passed after the bite. Additional symptoms of a more complicated infection may be:Pain in the joints
- Swollenness of the whole limb
To avoid those symptoms, follow these tips on how to get rid of rats and minimize the chances of getting bitten by a rodent.
You wouldn’t think it to look at them, but the common mosquito is the deadliest animal on the planet. Mosquitos carry diseases like malaria, encephalitis, and the West Nile Virus, which the females of the species like to transmit to humans whenever they can.
In developed nations like the United States, deaths from mosquito bites and transmitted diseases are rare, but throughout the world, they account for around one million deaths each year.
Mosquito bites are caused by female mosquitoes feeding on your blood. Female mosquitoes have a mouthpart made to pierce skin and siphon off blood. Males lack this blood-sucking ability because they don't produce eggs and so have no need for protein in blood.
As a biting mosquito fills itself with blood, it injects saliva into your skin. Proteins in the saliva trigger a mild immune system reaction that results in the characteristic itching and bump.
Mosquitoes select their victims by evaluating scent, exhaled carbon dioxide and the chemicals in a person's sweat.
Symptoms Mosquito bite signs include:
- A puffy, white and reddish bump that appears a few minutes after the bite
- A hard, itchy, reddish-brown bump, or multiple bumps, appearing a day or so after the bite or bites
- Small blisters instead of hard bumps
- Dark spots that look like bruises
More-severe reactions may be experienced by children, adults not previously exposed to the type of mosquito that bit them, and people with immune system disorders. In these people, mosquito bites sometimes trigger:
- A large area of swelling and redness
- Low-grade fever
- Swollen lymph nodes
Children are more likely to develop a severe reaction than are adults, because many adults have had mosquito bites throughout their lives and become desensitized.
