Orb spiders are hard to identify based on their appearance, because there are so many different types. The best way to identify them is the appearance of their webs. The orb spider gets its name from their distinct round wheel shaped webs. Orb spiders are also called garden spiders, because they are most commonly found in landscaping. These spiders are mostly nocturnal and do not hunt for their prey. They will bite if they are threatened, but there is not any danger to their bite. Whether they are dangerous or not, no one wants spiders crawling around their homes. If you think you have an orb spider infestation, call Nashville Pest Control.
Appearance and Life-cycle:
The orb spider family has a large number of species, which can make it hard to distinguish them from one another. They can range from 1/4th of an inch long to 1-inch long. They can be anywhere from light brown to black in color. The nocturnal spiders are typically brown or grey in color, but the diurnal species, meaning active during the day, can have different brightly colored markings, like yellow, orange, and red. They have hairy or spiny legs. The males are smaller than the females. The orb spider’s main purpose is to mate with a female. Because of their size, the male is often the female’s first meal after mating. The females can produce one or more egg sacs. Each egg sac can have as many as several hundred eggs.
Habitat and Behavior:
The webs are the best way to identify them from other species. Their webs are organized and circular grids. They look like the webs in Halloween decorations. Their webs are strong and can be up to 60 cm in diameter.
Most of the species are nocturnal and will build or repair their webs at night. Some even tear down and consume the webs in the mornings. They do this, so they can take in moisture from the dew that settled on the web.
Orb spiders are not hunters or wanders, instead they wait for prey to get tangled in their web. If they do leave their web, they do not go far and are always aware of the possible prey that can get caught in their web.
Orb spiders build their webs in branches of trees, bushes in gardens, corners of doorways, porches and decks. The bugs they eat are attracted to light, so their webs can be found near porch lights and other light sources.
Their diet generally consists of small insects, like flies, moths, beetles, wasps, and mosquitoes. Larger spiders may even trap small frogs and humming birds.
Level of Danger:
The orb spider will bite when they are cornered, but they are not aggressive. There is not much danger to humans from the bite; the venom is not strong enough to affect someone. The skin around the bite becomes raised and red.
Signs of Infestation:
The most obvious sign of an orb spider infestation is the presence of their webs. They are typically found in the late summer and fall.
The best way to prevent an orb spider infestation is to keep trees away from the home. It is also important to reduce the number of insects the spider eats around the home. Sealing the cracks in the foundation, near doors, and windows will also prevent these spiders from entering your home.
If you see any sign of these, or any other spiders, it is best to call Nashville Pest Control to get rid of them for you. They can correctly identify the pest and provide the best course of action for removing the problem.
