Why Do Spiders Bite Humans?
Spiders don’t bite humans. They do, however, bite in self-defense. Their venom is designed to immobilize prey, much like snake venom, but they are not equipped to puncture human skin. The best defense is to avoid them.
Some spiders, such as jumping spiders and funnel web spiders, can be dangerous. However, most spiders are harmless. This includes the black widow and redback spiders.
A spider bite is a minor irritation that causes redness, itching, and swelling. You’ll also see a small lump in your skin, similar to a bee sting. It will go away after a few days.
If you are bitten by a tarantula, you’ll see the same redness and swelling. These large arachnids are found throughout the Southwestern states.
A venomous spider’s sting can cause serious harm. There are fewer than a dozen species of spiders that could injure an average human. Venom is a toxic mixture of chemicals, including proteins and neurotoxins. In addition to being a potential source of disease, spider venom may break down and disintegrate prey.
Spiders also feed on honeydew, pollen, and silk from their own webs. Some of these eat insects, while others eat seeds. Most species are harmless, but there are a few notable exceptions, such as the brown recluse spider.
Spiders will only bite you if they feel threatened. Their fangs are also a good way to immobilize their prey. To prevent a sting, you should use a cold cloth on the area.
