What Do Giant House Spiders Look Like?

As their name implies, the most distinctive visual indicator of giant house spiders is their size; giant house spiders are some of the largest spiders found in the United States. Their bodies can grow up to an inch long, and their full width including their legs can grow to 4 or 5 inches in length. They are brown and hairy, with distinctive pincers.

These spiders can be found all throughout the Puget Sound area. Giant house spiders are named so in part because of their penchant to make their way indoors. Like most spiders, giant house spiders prefer dark and damp places such as garages, basements, and cracks in the pavement. They are nocturnal and will spend nights active hunting their prey.

How Do Giant House Spiders Behave?

Giant house spiders are some of the fastest spiders in the world and have been clocked at a speed of 1.7 feet per second. Because of their speed and their size, you may be able to hear them scurry if you aren’t able to see them. Giant house spiders construct webs to trap their prey and spend much of their time waiting for prey to arrive. While their speed is impressive, giant house spiders aren’t great climbers, unlike other spiders. And though they can and do sometimes bite, their venom is not medically significant to humans.

What Do Jumping Spiders Look Like?

Jumping spiders can come in a variety of colors, including iridescence. They can have black and white markings on their abdomen and different colored mouthparts (called chelicerae). They also come in varying sizes, though they are usually 1/2 inch long or smaller.

Where Can I Find Jumping Spiders?

Outdoors, you’ll find jumping spiders in yards, grasslands, and prairie areas. Indoors, you might find jumping spiders near windowsills and doorjambs. Jumping spiders are among the more common spiders to be found out in the open. 

How Do Jumping Spiders Behave? 

Jumping spiders only bite in self-defense. Although the bite itself may hurt, they do not carry venom that exerts any other effects. As you might expect from their name, jumping spiders can and do jump. Their jump is anywhere from 10 to 40 times their body length, and they are also some of the fastest-moving spiders.

Orb Weaver Spider

Orb Weaver Spider

What Do Orb Weaver Spiders Look Like?

Orb weaver spiders comprise a wide group of smaller sub-species of spiders. As a result, while many orb spiders are shades of brown or grey, others can have other colors including orange and black. Most orb spiders are less than 1-1/2 inches in length. The most distinctive visual aspect to orb weavers is the large, intricate webs they weave.

Where Can I Find Orb Weaver Spiders?

Orb weavers are usually seen near their webs, which they set up in areas where they are most likely to catch prey. These webs are commonly found in bushes, tall grass, and around night lights. Orb weaver spiders themselves will spend time in a nearby hiding place.

How Do Orb Weaver Spiders Behave?

Unlike some other spiders, orb weavers do not hunt or gather. Rather, they wait for their food to get caught in their web, wrap them in silk, and paralyze them with their venom. Orb weaver spiders reweave their web every day. Female orb weavers will create an egg sac, which hatches many baby orb weavers once they are ready. An orb weaver bite, which does contain venom, is nevertheless no more dangerous than a bee sting and does not present serious danger unless you are allergic to the venom.

Wolf Spider

Wolf spiders are large spiders that can be up to 2 inches long. They often have gray, black, or brown colored patterns on their bodies. Although they have shorter legs than other spiders, they are thicker with a larger abdomen. As their name might imply, wolf spiders are also very hairy.

Where Can I Find Wolf Spiders?

Outdoors, you’ll find them in and around their burrows in the ground. Inside, you can find them in and around houseplants and windows as well as in basements and garages. Wolf spiders make their way indoors as it gets cooler during the fall. 

How Do Wolf Spiders Behave? 

Unlike many other spiders, wolf spiders live within burrows instead of spinning webs, though they may create silk doors for the burrows. Female wolf spiders create egg sacs out of eggs and silk, placing them in their burrows. They have keen senses, including excellent vision. Wolf spider bites are not deadly, though they can be painful, cause redness and swelling, and include venom that may trigger allergic reactions.

Where Can I Find Yellow Sac Spiders?

Yellow sac spiders are normally outdoor spiders and won’t prioritize getting into buildings and homes. However, they will take the opportunity to do so if they find the right conditions for feeding and breeding. You can find them in nooks and crannies, especially along baseboards and under furniture.

How Do Yellow Sac Spiders Behave?

Yellow sac spiders are nocturnal and hunt for small insects or smaller spiders at night. As a result of their activity, they come into contact with humans more often than many other spiders.
