The Orb weaver spider makes a two-dimensional circular web. This is one of the most familiar types of webs, which may span up to 8 inches, and consists of stretchy spiral silk. The orb web is specifically engineered to capture flying insects. They are well known because they grow to be large, conspicuous, and colorful. There are several types of orb-weavers, preferring to live in moist wooded environments, especially along streams, rivers, or near swamps.

Identifying an Orb Weaver Spider

It can be hard to identify an orb-weaver due to the fact that it is one of the most varies in size and appearance of all spider families. The easiest way to identify an orb-weaver is through its web, which resembles the typical circular spider web depicted in popular culture. Orb weavers vary in color, but many of them have brightly colored bodies as well as hairy legs. Most orb-weavers are nocturnal, meaning they will only be seen at night, especially when they are constructing their nest.

Orb Weaver Spider Habits

Unlike a lot of spiders, orb-weavers are not hunters and use their webs to catch their prey. Orb-weavers prefer to feed on insects such as flies, moths, beetles, and more. These spiders are most often seen in late summer and fall outside in gardens and yards, often in tree branches, weeds, walls, bushes, and more. For the most part, orb-weavers are not considered to be a threat to humans. In the rare case a human is bitten by an orb-weaver, they will likely not have any serious symptoms.

Get Rid of Orb Weaver Spiders

Your Ehrlich Pest Control, formerly Connor’s technician will:

  • Determine the type of spider.
  • Conduct a full property inspection that includes your yard, attached & detached structures, driveway, and home.
  • Directly treat spider-nests outside your foundation to protect your home during the warmer months along with their food source (other insects).
  • Physically remove webs from the outside and inside of your home.
  • Seal small common entry points if they are contributing to the infestation.
  • Discreetly apply the material in unfinished basements, voids, and other spider-frequented areas when evidence is noted.
  • Place “sticky traps” on the interior to monitor activity.
  • Create a full report describing the treatment and how you can protect your home from further infestations including:
    • Changing the lighting around your structure.
    • Eliminate clutter inside and outside of your structure.
