The common orb weavers are the spiders so often seen in gardens, where they construct large, circular, symmetrical webs in pathways, on arbors, and in other areas. They do not inhabit structures, but are such large and obvious spiders in the outdoors that they are attention getters. There are two major groups of these large, colorful spiders, and many different species can be found. The webs may be over two or three feet in diameter and may actually be torn down and reconstructed nightly by the spider. Orb weavers are capable of biting humans, but their venom generally is not considered dangerous. They place themselves either near their web with a leg on it to detect prey that is caught, or often directly on the middle of the web where they may create an “X” of thicker webbing. Females may produce one or more large egg capsules in late summer, and then die shortly afterward.
There is little need to control these beneficial spiders, as they do not enter structures. If their presence in the garden is unwanted they can be physically removed and killed.
