Later in this article we take a look at the threat spiders pose to humans. First we take a look at the good things spiders do for us. Spiders reduce local disease carrying insects that would other wise be harmful to us humans. Eliminating these threats is of great benefit to our safety and health. Spiders provide humans with many other benefits one very significant being that of medical advances. Spider venom is used in neurological research. Spider venom works to prevent brain damage in stroke victims. The very silk used to create the many webs we so casually brush aside is used in many optical devices including laboratory instruments.
How Spiders are Helpful and Harmful to Humans
Spiders are both harmful and helpful to humans. While you may fear spiders have you considered the work they do regularly to benefit humans? Learn how spiders help us and hurt us.
Reasons to Fear Spiders
There are three reasons people should be cautious of spiders.
There are three ways in which some spiders are harmful to people.
The three harmful effects on human health attributed to spiders are;
- Allergic reactions
- Poison venom
- While few people experience allergic reactions to spider bites themselves,there are in fact those who are allergic to the dead cell particles of spiders similar to dust allergies.
- Poison due to spiders occurs when a person is bitten by a poisonous spider. You should seek medical attention if this occurs.
- Fear is the biggest factor of all three. More people are afraid of spiders than most any other creature on the planet, that being snakes.

Allergies to Spiders
People allergic to spiders experience allergic reactions similar to that of inhaling dust mites.
Allergies - There are people who are allergic to the hair and scales of spiders when inhaled, similar to the reaction many have with dust mites.
While this may seem rare there are those who have similar allergic reactions to other arthropods.
For example cockroaches are one such allergy. I personalty know of one person allergic to cockroaches.
There are people who think they are allergic to spider bites, this is not the case. Any reaction to a bite is due to the toxins present in the spider venom. Many spider bites, while not dangerous, create a reaction that is a normal reaction to the non poisonous venom yet not an allergic reaction.
People who are allergic to spiders are allergic to the spider deposits they inhale as outlined above.

Venom of Spiders
While some spider bites are not venomous others are highly toxic.
Venom - Spiders can inject venom through their bites. This is known as envenomization. There are more than 50 spider species known to be capable of biting humans. While this is true there are but two that are of the greatest threat.
The Black Widow
The black widow carries poisonous venom while it's bite has a negative impact on human health.
The Black Widow - This species injects a neurotoxic venom causing symptoms with little to no damage in most it's human victims. The symptoms of the black widow bite are sweating, weakness, muscle pain, nausea, tremors, and vomiting. In severe life threatening cases breathing difficulities, heart irregularities, and possible death in victims who are weak with compromised health such as the elderly and small children.
The Brown Recluse
The brown recluse is the most feared spider as it has the potential to destroy the flesh of the human body.
The Brow Recluse - Is an aggressive house spider injecting cytotoxic venom causing severe localized tissue damage and necrosis and yet rarely causing systemic damage. The bite of the brown recluse causes skin loss and ulceration that can take months to heal many times requiring skin grafts.
The Fear of Spiders
Spiders are feared more than anything else ranking ahead of the fear of snakes.
Note: With all the knowledge we've acquired spiders are among the most feared creatures on the earth still today. People who experience such intense fear induce physical illness upon seeing spiders.

Fake Spiders for Halloween
These spiders could be used for halloween or simply for scaring the day lights out of those afraid of spiders.
Oh but seriously consider this before you scare someone. I had an uncle, died prematurely from a heart attack, that was deathly afraid of spiders. He was a obnoxious sort we kids loved scaring the devil out of. He would turn three shades of white if ever we came running at him as we would find dead spiders and toss the at him. Seriously, once again I must say, this is something you should think twice before doing as we may have been one of the reasons he died young due to a heart attack.
