Spiders are feared or disliked by most, but they are beneficial for their role as predators of insects and other arthropods, and most are harmless to us, especially the ones we consider common house insects.
Spiders are arachnids, not insects. Many people confuse insects with spiders, spiders have eight legs and two body parts (a head region, and an abdomen). They lack the wings and antennae that insects have.
Most spiders have toxic venom, which they use to kill their prey. Most are harmless, or not toxic enough to cause a serious reaction in humans. So only spiders with venom that causes a serious reaction in humans are called "poisonous" spiders. There are a couple spiders that can be harmful to humans, they would be the Black Widow Spider, and the Recluse Spider.
