What are the white spiders in Oregon and Washington?

What are the white spiders in Oregon and Washington?

Zebra jumper

Zebra jumpers, also known as white spiders, are common wall-dwelling creatures found in many parts of the world. These spiders have excellent vision and can watch the people around them. They are generally considered harmless to humans, but they can bite if provoked.

Interestingly, zebra jumpers are one of the very few types of spiders that do not build webs to capture prey.

Instead, they stalk their prey much as cats do. This hunting method allows them to travel farther in search of food and makes them more successful predators.

Hobo spiders

The hobo spider is a species of spider that is found throughout the Pacific Northwest. They are one of the most unjustly detested house spiders in North America, but they are actually harmless to humans. They are often seen traveling on trains, hence the term “hobo.”

Hobo spiders have impressive skittering speeds and can be very difficult to catch. In Europe, where they originate, the hobo spider and all other related species are considered harmless.

Wolf Spiders

Wolf spiders are common spiders found in the Willamette Valley. They are abundant in gardens and can be easily identified by their large size and white markings on their backs.

The Wolf spider doesn’t weave a web to catch its prey; instead, they hunt its prey similarly to wolves, stalking and pouncing on their prey.

Orb weaver spiders (Araneus diadematus)

Orb weaver spiders are a type of spider that builds large webs to catch flies and other insects.

They hatch from egg sacs in the spring and may be noticed as juveniles because they are typically smaller than most other spiders. Orb weavers can eat a lot of flies and other flying insects.

Running crab spider

The running crab spider, also known as Philodromus dispar, is a small, brown spider that is found in the US and Canada. This crab spider does not build a web to catch prey; instead, it ambushes its prey.

Crab spiders are common indoors and can enter homes through cracks or openings. They are often mistaken for white spiders because of their light-colored abdomens.

Yellow Sac spiders

The yellow sac spider is a giant house spider found throughout the US but is believed to have originated in Europe. They are most active at night and hunt insects with their distinct eyes rather than building webs. They have a distinctive white patch on their abdomen.

Yellow sac spiders get their name from the small silk sacs they spin to hold their eggs. During the day, they hide in their sacs. These spiders are common in North America and can be found in many different environments.

Mouse spider

Mouse spider is the common name for the European spider species Cheiracanthium mildei. They are found in Oregon and Washington and are immigrants from Europe.

Mouse spiders are similar to the yellow sac spider, which is also found in these states. They are most often seen in summer on walls and ceilings, active at night, and hunt prey in a similar way.

Garden spiders

Garden spiders are found throughout North America. They are typically light in color, often white or yellow, and build webs in gardens and other outdoor areas. Garden spiders are not dangerous and typically do not bite humans.

The Cryptomaster behemoth

A new spider has been discovered in the mountainous and forested regions of southwest Oregon.

The spider, which has been named Cryptomaster behemoth, is a white spider that is closely related to the brown recluse spider. It is unclear what effect the Cryptomaster behemoth will have on the ecosystem or on human populations.

In fact, scientists believe that many more spiders are yet to be discovered in the same suborder as the Cryptomaster behemoth.

This white spider was only discovered a few years ago and is still being studied. It’s possible that there are other large, white spiders out there waiting to be found underneath.

Other species of spiders in Oregon and Washington

There are a number of different types of spiders found in Oregon and Washington, including the black widow spider. This is a venomous spider that should be treated as potentially serious if bitten.

There are also several other species of spiders that can cause harm, so it is important to be aware of their presence and take steps to avoid them.

Oregon and Washington are home to the brown recluse spider as well. This spider is rarely seen in these states, but other types of spiders are commonly found there. These include the black widow spider, the hobo spider, and the yellow sac spider.

The black house spider is common in the United States. They are typically outdoor species but can be found in buildings. They are known for their webbing, which is built into protected areas such as under leaves or porch ceilings.

What if a white spider bites me?

If a white spider bites you, you should first wash the bite area with soap and water. There are some other things you can do to reduce the risk of infection.

  • Avoid scratching the wound with soap and water, and keep it elevated if possible.
  • If the symptoms don’t improve after a few days, seek medical attention.

How do I prevent spider bites?

In order to prevent spider bites, it is important to take some preventive measures.

  • First of all, keep spiders from crawling into bed with you by moving beds away from the walls and removing bed skirts and other items stored under the bed.
  • Inspect firewood, potted plants, and other objects before bringing them inside your house. Keep woodpiles, rock piles, shrubbery, and other objects away from the outer walls of your house.
  • Check your clothing and shoes before putting them on.
  • Wear protective clothing when handling stored items, and use insect repellent.
  • Use tight-fitting screens on windows and doors. This will keep the spiders from entering your home.
  • Additionally, clear away any clutter, such as old furniture, boxes, or clothes that sit in undisturbed areas of your home or garage. Spiders love to hide in these places, so they’re less likely to bite you if you remove the temptation.

What are the symptoms of a bite?

Spider bites cause a variety of symptoms, depending on the species of spider. Most spider bites cause only minor and temporary symptoms, such as redness and swelling at the bite site. However, some venomous spider bites are more serious and may require medical attention.

Spider bites pose a serious health risk to the very young, the elderly, and those with high blood pressure and weakened immune systems.

The venom of some spiders can cause necrosis and permanent damage to skin tissue. It is important to seek medical attention as soon as possible if you think a spider has bitten you.

Can people be allergic to spider venom?

People can be allergic to spider venom, and it can cause anaphylaxis, which is a potentially life-threatening reaction.

The symptoms of anaphylaxis are swelling of the throat, chest tightness, rapid pulse, dizziness, and, in some cases, death.

Final Thoughts

Spiders play a crucial role in controlling harmful insects. While some people may be afraid of them, they are beneficial and should be protected.

Though they may be small and often feared, white spiders are very common in Oregon and Washington. They help control the populations of other insects and pests in the houses of these states.

So next time you see a spider, remember that it is an important part of our world, even if it looks scary.
