Are Orange Spiders Poisonous?
It’s not uncommon to see orange spiders or what looks like an orange spider in North America. The good news is that they are not considered dangerous to humans. Most will give a painful bite but are not considered medically significant.
The only orange spider of concern is the brown widow, with an orange hourglass shape on the belly. This spider may not be as poisonous as the black widow, but they still give a painful bite, with redness and swelling, which is limited to the bite area.
Summary
There are a number of spiders that are orange, have orange on them or look orange, due to their red/brown or yellow/brown coloration. The spiders listed mostly live outdoors but can be encountered in back yards and inside homes from time to time.
