The giant house spider, also known as Eratigena atrica, is a species of spider that is commonly found in the Pacific Northwest region of North America, including Oregon. These spiders are known for their impressive size, with some specimens reaching leg spans of up to 4 inches (10 cm) or more.
In terms of body length, giant house spiders in Oregon typically range from about 0.5 to 1.5 inches (1.3 to 3.8 cm) in length, with a leg span that can be up to 2-3 times their body length. This means that some giant house spiders in Oregon can have a leg span of up to 3-4.5 inches (7.6 to 11.4 cm) or more, making them one of the largest spiders in the region.
It’s worth noting that the size of giant house spiders can vary depending on factors such as diet, age, and environmental conditions. Female giant house spiders tend to be larger than males, and spiders that have access to a steady food supply may grow larger than those that do not.
Despite their impressive size, giant house spiders are generally harmless to humans and can actually be beneficial to have around the house. They feed on insects and other small arthropods, helping to keep pest populations under control. However, some people may still find them intimidating or unpleasant to look at, and may want to take steps to prevent them from entering their homes.
