When you'll see bold jumping spiders

Bold Jumping Spiders are most active in spring, summer and fall. In spring, overwintering adults become active and many species lay their first eggs. Summer heat speeds up development, so populations can grow quickly. In fall, many bugs look for shelter, and some move toward or into buildings.

Typical places to check: indoors, anywhere and garden or plants.

About spiders

The bold jumping spider is one of the spiders. Spiders have eight legs, two main body sections and no antennae. Almost all spiders have venom to subdue prey, but only a few have venom that matters to people. Many build webs, while others, such as wolf spiders and jumping spiders, hunt on foot.

Spiders go where their food is. A home with lots of spiders usually has plenty of other insects, so general pest control reduces spiders too.

Should you get rid of it?

No control is needed. Bold Jumping Spiders are not pests, and many help by eating other insects or pollinating plants. If one is indoors, move it outside with a cup and a sheet of paper.
