How Did I Get Yellow Garden Spiders?

Plants and flowers exposed to bright sunlight are the perfect place for a yellow garden spider to build its wide, intricate web. The pests tend to settle long-term in yards with plenty of insect prey. Yellow garden spiders are an attractive yellow and black colored species that spin large webs containing a zigzag patterned portion of the web known as the stabilimentum.

Since these orb weavers are common in lawns and gardens, yellow garden spiders may accidentally wander indoors. They often anchor their large webs to door frames and windowsills, which can also contribute to them getting inside.

How Serious Are Yellow Garden Spiders?

Many people fear yellow garden spiders because they are large and brightly colored. However, these pests do not bite unless touched or injured. The pain of a yellow garden spider bite is similar to a bee sting. In general, these arachnids are not harmful, but they may frighten residents when they invade homes.

Behavior, Diet, Habitats

Webs

The yellow garden spider is known for its ability to spin incredibly complex web patterns. Anchored to branches, twigs, plant stems and other structures, their webs are extremely strong and can reach diameters as large as 60 cm. Yellow garden spider webs can withstand the weight of numerous trapped insects.

The yellow garden spider hangs at the center of its web while waiting for food to come. It senses the presence of prey when the lines of its web begin to vibrate. The yellow garden spider then moves quickly to immobilize prey and to encase it in silk.
