Spiders do not intentionally bite a human, except they are provocative or in a dangerous situation, for example, if they are about to be stepped down, or if a person is sat on the top of the spider.
Most of the spider bites are harmless, but being bitten by a venomous spider can be a scary experience since, although rarely, the effects of its venom can be fatal.
The first thing you should do is seeking for medical help. But while waiting for the medical treatment, here are several things you have to do if you believe that you have been bitten by a venomous spider:
- Keep calm.
- Clean the bitten site. Wash the wound with soap and water.
- Put some drops of antibiotic ointment.
- Cool compress the bitten site. You can soak a towel or clean cloth into cold water, or you can make an ice compress by putting some ice cubes in the cloth and apply it to the wound.
- Stop any activity immediately and limit the movements. If available, use a splinting to immobilize the bitten area. But do not make it too tight, it may affect the blood circulation.
- Try to remember characteristics of the spider (or if it is possible, you or people around you can catch the spider): its color, its shape, and the patterns on its body. It is important for you to have a mental picture of the spider and describe it to the medical staff at the hospital so that it is easier to give a proper help.
Here are things you must avoid if you are bitten by a venomous spider:
- Do not move a lot, try to stay still. Moving around will make venom spread faster.
- Do not try to remove the venom by yourself.

So how do you know that the one who bites you is really a venomous spider?
Several dangerous spiders have their own characteristics, so you can tell if the one which bites you is the venomous one or not by identifying its color, shape, and the patterns on its body.
