No, not everyone is allergic to brown recluse bites. Many times the reaction comes from the venom. If however someone is allergic and also reacts to the venom it could cause some medical complications especially for the elderly and children.
No not every one is allergic to poison ivy. About 3 out of 4 people are allergic to poison ivy.
No. About 5%-10% of people in the world are not allergic to the material in poison ivy, oak, and sumac that makes most people itch and develop a rash.
No, it is not possible to be immune to Poison Ivy. Some people do not have a reaction to it after exposure but this is because they have not become sensitized to it. In many cases, people do not have reactions to the toxic substance (urushiol) in the plant when they are children but, once they become sensitized to it later in life they DO develop reactions.
'Immunity' refers to diseases (pathogens), not substances. A person becomes immune to a pathogen when, AFTER EXPOSURE their body develops antibodies sufficient to prevent development of the disease.
yes
no, while the oil on the plant causes a rash and an itch that is not an allergic reaction. if someone is actually allergic the person would breakout in big blisters and would start to swell if not treated in time.
They are also not able to use something on the skin to sooth the rash such as calamine lotion. They have to take a physical medication in order to get rid of the blisters, rashes, swelling, and pain.
I myself only know this because I am allergic to poison ivy and poison oak and this was explained to me by my doctor.

yes i had a friend who died from a spider bite she was only 25
Yes, the brown recluse and the hobo spider bites can cause necrosis, where the flesh sloughs off around the bite area.
nothing it has to get into your bloodstream unless it bites you on the way down witch i highley dout
They actually aren't very alike at all. Brown recluse spiders are of the family Sicariidae. They have necrotic venom. Necrotic venom causes tissue death, hence why victims of brown recluse bites often have large, gaping wounds where they were bit. Deaths occurring from brown recluse bites are usually not due to the bite or venom, but because of infection in the wound. Both males and females are equally venemous. There is currently no antivenom for brown recluse bites. Black widows are of the family Theridiidae. Their venom is neurotoxic. Instead of killing tissue, neurotoxic venom attacks the body's systems, acting at the junction of motor nerves, muscles, and peripheral nerves causing increasing pain and difficulty breathing because of severe chest pain. Only females are large enough to pierce human skin. There is an antivenom for black widow bites, however many people are just as allergic to it as they are the bite itself. These patients have to stay in the hospital for weeks and wait out the effects of the venom until it passes.
No, not everyone has an allergic reaction to the bite of the brown recluse spider. In fact most people don't have an allergic reaction. But people do react to the venom the spider injects. It's powerfully toxic and can pose a deadly threat in young children or the older or infirm. Certainly if someone has an allergic reaction to the venom in addition to the effects of the toxins, this will complicate medical treatment and make the bite a much more serious threat to life.
The act of stinging does not kill the Brown Recluse the way stinging kills honeybees. However, the Brown Recluse typically bites humans in defense, so it's already in extremis -- it's not unusual for the spider to be discovered dead as a result of being crushed, after stinging.

Death from a Brown Recluse Spider is rare and has not been professionally estimated by year round averages.

Yes, the brown recluse and the hobo spider bites can cause necrosis, where the flesh sloughs off around the bite area.
No they are not. Brown recluse are some of the most poisonous spiders in the USA. Wood spiders, though can be considered close in appearance, are actually harmless (fright and allergic reactions aside).
Fatalities are extremely rare but a visit to your physician or local hospital is a must.
when sitting on it, is the easy answer. most bites occur when someone sits on a spider.
Around the world, people deal with various types of dangerous insects and arachnids. In many parts of the world, insect bites are extremely dangerous due to a lack of local health care options. Although brown recluse spiders are generally very small, their venom is incredibly dangerous. These spiders are generally medium brown, though they are occasionally gray or dark gray bordering on black. Their bodies are angular and segmented and almost appear similar to crabs' bodies. Fortunately for human beings, these spiders are fairly easy to identify. Though many other spiders have similar shapes and colorations, brown recluses are among only a few spiders that have three pairs of eyes. With their six eyes, brown recluses are quite unique and singular in appearance. Brown recluse spiders are naturally found in parts of the American Southwest and in part of the southern Midwest. Every year, people mistakenly identify these spiders in places outside their known range. Because of this false reportage, the public has gained a fear of recluse bites that borders on hysteria. In fact, these spiders have entered the folklore of many states where no specimens can be found. Brown recluse bites are occasionally very serious. They can lead to necrosis, gangrene and even the loss of limbs. However, these bites are only deadly in a tiny percentage of cases. Groups most vulnerable include the elderly, young children and those with compromised immune systems. Research has shown that the great majority of reported brown recluse bites are not recluse bites at all. Medical professionals routinely misdiagnose necrotic wounds as brown recluse wounds. Suspected brown recluse bites often turn out to be symptoms of Lyme disease, fungal infections or STDs. Doctors and patients should keep open minds when analyzing potential brown recluse bites. Misdiagnosis can have life-threatening effects. Unfortunately, doctors and medical responders are hampered by their lack of knowledge in the field of arachnology. Other types of spiders can trouble people with frightening bites. Hobo spiders and yellow sac spiders can cause necrotic bite wounds. In most cases, these bites are relatively harmless. While brown recluse bites are potentially deadly, brown recluse spiders are generally not aggressive. These spiders usually only bite when directly pressed against skin.
The brown recluse does not have a backbone.
