Spiders usually do not bite people whilst they are sleeping, in fact it is rather not common for spiders to bite you whilst you are sleeping. But in some cases when it does happen why does it happen, well let’s start off by answering the question “Why Do Spiders Bite You When You Sleep?” right away:
“It happens because the spider was unintentionally disturbed by you whilst you were sleeping and it came on your bed. It could be your hand moving and hitting the spider whilst you were changing side, or it getting tangled in your bedsheet due to your leg movement. Spiders do not usually bite unless they sense threat from their environment”.
Another thing to note at this point is that many times a mark that is suspected to be a spider bite isn’t a spider and it occupies the mind of many people because of the old myth of spiders roaming around sleeping people, biting them or even getting eaten by them, al of which are just myths, but they have somehow embedded themselves
How Do Spiders Bite?
Spiders usually have fangs that they use whilst taking a bite at their opponent, whilst taking the bite, they are also using their legs to grapple their opponent as hard as they can. Venomous spiders produce and pump their venom into their prey using these very fangs. Another very interesting thing to note at this point is that spiders like the black widow before actually biting their opponent fully first do a warning bite in which they do not pump as much as venom and this bite is supposed to act as the warning for their opponent to move away or not disturb them. And then they go on to bite their opponent with the real deal. However deadly spiders like the funnel-web spiders do not do a warning bite and bite as hard as possible and pump as much venom as possible into their
Are Spiders Interested In Biting Humans?
No, spiders are not at all interested in binting humans. But they will however bite you if you proceed to be a threat to them or keep poking them. This is just a defense mechanism that a spider resorts to when it senses threat
Can Spider Bites Be Lethal?
Yes, there are quite a few spiders, a bite from which can put you very well on your way to a hospital, but not only are they not in our proximity, even if one of them gets near us, they really aren’t interested in biting humans at least not unless they are highly disturbed or threatened again and again. So most of the times spiders do not pose much of a problem and even the worst of them do not want to bite you whatsoever
Spiders That Can Kill You If They Bite You
Spiders don’t really like to bite humans, most of the time they would just run away or sometimes play dead. Most spiders only bite when they are protecting their eggs, and although some spiders are venomous enough to kill humans, most spider bites, if treated in time, are not fatal.
Black widow spiders are probably the most famous in this list. They are highly venomous, and they are named ‘Black Widow’ because after mating they kill the male spiders. They are 1 inch long and their male counterparts, which are seldom seen are about 0.25 inches long. They can also be uniquely identified as they have an hourglass shape on their abdomen which is red in color.
They are widespread in North America and they have enough venom to kill humans, but very rarely do humans die from their bite if treated well. Mostly infants and elders are at risk of death. Their bite feels like a pinprick on the skin and can cause muscle cramps and nausea.
Brown Widow spiders are also widespread around the world and can be seen making their homes in buildings and under automobiles. This spider has a brownish appearance and markings which can differ from dark-brown, black, yellow, white, or orange in color. They also have an hourglass design on their underside but unlike the black widow spiders, it’s orange in color.
Brown Widow spider’s venom is much stronger than that of Black Widow spider, almost two times. However, the species is not aggressive and it injects only a small amount of venom. Their bites can kill humans if the bite is not treated properly and in time.
Another one from the widow family, this spider is differentiated from other widow spiders because it has red legs and cephalothorax. They are 1.5 to 2 inches long and they also have a red hourglass marking on the underside of their abdomen.
They are widespread in Florida but researchers think they might be spreading to other areas as well. They feed mainly on insects and are not aggressive towards humans. However, they may bite humans while protecting their eggs. The bite of a red widow spider is similar to that of a black widow spider, similarly, it has the same symptoms and death is rare given the bite is properly treated.
The redback spider is another one from the family of black widow spiders, but they are not as widely spread as the black widow. It is native to Australia but now has spread to other countries like New Zealand. It is widespread in Australia found in almost all areas. It is named because it has an hourglass shape on its black back.
These spiders are not aggressive and they like to play dead when disturbed, but a female spider who is defending its eggs may bite. Bites also occur when these spiders are stuck in shoes and clothes. They are highly venomous and their bites cause pain, sweating, raised heartbeat, and swollen lymph nodes. They rarely cause death, but it mostly depends on how much venom is delivered to the body.
These spiders are named because they make funnel-shaped webs, they are spread in North America, South America, and Australia. These are large bulky spiders which are heavily feared because they are highly venomous. Several human deaths have been recorded since the 1920s, and although an antidote has been developed. It has to be supplied soon after the bite or the bite may cause death.
White Widow Spiders
White widow spiders are highly venomous and are mostly found in Russia, Kazakhstan, and some other Asian countries. Unlike most widow species that are black in color, this spider is of a lighter color although the shape of the spider looks similar to other widow spiders.
White widow spiders also kill their male counterparts after mating, and they are capable of killing infants but it is very unlikely for them to be able to kill adult humans
