About 300 varieties exist in the US and are known for their jumping ability which they use to hunt. They are an occasional nuisance pest indoors, and some colored species may cause concern when people mistake them for Black Widow spiders. .
Jumping spiders do not construct snare webs but do build homes with two openings in a woven, saclike structure. Jumping spiders are active during the daytime and do not shun sunshine. While they possess acute daytime vision being able to detect and react to movement up to 18″ away; they have very poor night vision. They can rapidly move and jump in all directions for short distances.
Jumping spiders can live in forests, grassland, under furniture or any location that has enough food and shelter. They can be seen hunting on trees and near windows and doors where other insects are found.
While they can bite, the jumping spider bite is not poisonous. They are not usually considered dangerous. If symptoms arise, consult a physician.
Seal all cracks and screen windows and doors. Inspect bags and boxes before bringing them into your home.
