This brightly colored spider is less the ½ inch in length and has a hard, white abdomen with red markings and black spines protruding from the edges.
BEHAVIOR:
The spiny-backed orb weaver spins flat, orb-shaped webs in trees, corners of windows, soffits and outdoor areas of buildings. These spiders capture flying insects found around a home. They are not dangerous and would easily be overlooked if not for their large webs. They do not invade indoors unless carried inside while living in a potted plant.
HABITATS
This spider is common along the southeast coast of the United States and is a regular inhabitant of yards in Florida.
TIPS FOR CONTROL
Spiny-backed orb weavers are not dangerous and are beneficial animals. They should not be killed if at all possible. In situations where numerous spiders are present, the webs can be regularly knocked down by using the Bugly web brush. If large amounts of spiders are around your home, look to see what may be attracting them. You may want to switch exterior light fixtures to yellow “bug lights,” which attract far fewer flying insects. Also, treat the exterior home with Bugly Outdoor spray.
