By using different methods to capture prey, they are able to feed to stay alive. Mygalomorph spiders ambush their prey and typically do this by waiting for passing prey in burrows. Flower, crab, and wolf spiders actually hunt their prey using good eyesight and strong front legs to hold their prey after chasing them down.

Without spiders many of the animals that we as human deem as pests would get out of control such as house flies, crickets, roaches and other undesirables.

Spiders also are also food for humans in some cultures and for many animals such as birds and frogs.

Jumping spider.Although spiders are interesting and sometimes captivating animals, they should all be handled with care because of their often deadly drawback. Many spiders are poisonous, but most poisonous spiders are not deadly. This may be true in most cases, but reactions to spider venom vary from person to person meaning that some may have severe allergic reactions while other may not. Beyond the differences in human reaction to venom, not every hospital carries anti-venom for spider bites making it nearly impossible to get immediate treatment if bitten. Some popular poisonous spiders are the previously stated black and brown widow, funnel web, red-back, white tailed, and mouse spiders all of which have potentially deadly bites varying on reaction. To help avoid a spider bite, be sure to use the 'look before you reach rule' when around abandoned, cluttered, dark, damp, and dank areas. Spiders can also be detected in the dark by holding a flash light at eyelevel and seeing the reflection of their eyes back at yours.
