Is There An Orb Weaver Season?

Is There An Orb Weaver Season?

Orb weavers are a broad family of spiders found throughout the United States and Canada. The orb weaver is known for the large, majestic web it weaves. These webs are commonly found on tree branches, in tall grass, bushes, and around light fixtures. They are often found where abundant food sources are available (in your yard or garden, near lights that are on at night, etc.).

Most orb weavers appear in the spring when their eggs hatch, but they aren’t really noticed until late summer and fall (when the males go out in search of their mates). Female orb weavers hang out in their webs, eating and waiting on a male to come find them. Males are always on the move, rarely building webs, searching for a partner. At the end of fall, females will lay their eggs and then die during the first frost. Males typically die after mating. Because of their structure, orb weaver eggs can survive the cold weather of winter. When the weather warms up in the spring, the eggs hatch, releasing a new brood of orb weaver babies.

These spiders are known to be docile and non-aggressive. They rarely bite and aren’t considered dangerous to humans or pets. In fact, they can be beneficial to have around as they trap and eat other pests that can infest your home.

Prevention is unnecessary with orb weavers unless their web is built in an inconvenient location or a location with high human traffic. They cause no structural damage. You can lessen your chances of encountering orb weavers by:

  • Removing their food sources by keeping other pest populations under control around your home
  • Sealing any cracks, gaps, and crevices in your home’s exterior
  • Removing ground litter
  • Trimming grass and bushes

If you have a problem with orb weavers or any other pests, contact your local pest control company.

How Dangerous Are Orb Weavers?

How Dangerous Are Orb Weavers?

Orb weavers can be scary looking with their large size and the giant webs they weave. But are they dangerous to humans or pets?

The short answer is no. Although these spiders can bite, they lack the potent venom needed to cause serious damage to humans or larger animals. Their bites are comparable to bee stings. These pests are quite docile and usually non-aggressive; they are more likely to flee from you than to attack and bite you if disturbed.

Orb weavers are garden pests, often found in bushes, trees, wood piles, yard debris, under porches, under roofs, and under eaves. They get their name from the large, circular, wagon wheel shaped webs they weave. Because their family is so diverse, these spiders come in a variety of colors and markings, with some of the more common ones being bright yellow and black.

Orb weavers eat a variety of small insects such as mosquitoes, beetles, moths, flies, and wasps. They are quite beneficial to have around as they help keep other pest populations under control.

If you have an issue with spiders or other pests, contact your local pest control company for an evaluation and treatment options.

Orb Weavers: What You Need to Know

Orb Weavers: What You Need to Know

Orb weaver spiders, or orb weavers, are a group of spiders named for their ability to produce round, orb-like webs. They make up the family Araneidae, one of the most diverse groups of arachnids in terms of both size and appearance. Despite their differences, they all have one thing in common: their ability to create large, majestic webs. These webs are circular in shape with grids similar to the spokes of a wheel. Some webs can even measure up to 3 feet in diameter. Let’s take an in depth look to learn all you need to know about orb weavers.

Appearance

Orb weavers have body types similar to other spiders with 8 legs; 2 body parts (a cephalothorax and abdomen), and chelicera (mouthparts that look like fangs). They range in size from 1.5 to 3 cm. Some are brightly colored, while others are brown or gray. They have large abdomens and hairy legs.

Behavior

Orb weavers are typically nocturnal and will often build or repair their webs at night. They do not hunt or wander for their food. Instead, they utilize their expansive web making skills to catch their prey. They will usually sit in their webs after they are built waiting for prey to become ensnared. Sometimes they will hide nearby and leave a trigger line of silk connected to the web. The vibrations from the prey run down the line and alert them. They will then bite and paralyze their prey and wrap it in silk to save for dinner later. Orb weavers are most commonly seen in late summer and early fall.

Diet

An orb weaver’s diet usually consists of small insects like moths, wasps, beetles, flies, and mosquitoes. Larger spiders will also eat small frogs and hummingbirds.

Habitat

Orb weavers will take up residence where there is an abundance of prey for them to eat. They can often be found around outdoor lights, tall grass, weeds, fences, bushes, and walls. They can be found in any environment including gardens, grasslands, and cities. Orb weavers are found on every continent except Antarctica and in the Arctic. There are 2800 species worldwide and 180 species in North America.

Prevention is not necessary with orb weavers unless their web is constructed in an inconvenient area or an area with high human traffic. In fact, they can be beneficial to have around as they help keep other pests under control around your home. They don’t cause structural damage and they rarely bite (only if threatened and they cannot escape). Their bite has been compared to a bee sting. You can reduce the chances of having orb weavers around by:

  • Eliminating their food sources by keeping other pest populations under control around your home
  • Sealing any cracks, gaps, and crevices in the exterior of your home
  • Removing ground litter
  • Keeping grass and bushes trimmed

If you have a problem with orb weavers or any other pests, contact your local pest control company for an evaluation and treatment plan.
