Hobo spiders are one of the most common household spiders in Western North America. They are not known to be a dangerously venomous species, however, will become extremely aggressive when their egg sac is being threatened. They generally do not bite unless forced to protect themselves. They’re easily identified by their light stripe running down the middle of their sternum.
Many homeowners say: “I don’t have any bugs; I just have spiders.” This is a common misconception. Spiders are predators; the only reason they’re in a home is because they have enough food prey to stay alive. Spiders feed on the smaller and sneakier pests that most people don’t see. Most homeowners dislike having spiders and their webs in and around their home, especially if they have younger children. Spiders are extremely resilient, and despite having their webs removed, they will often come back to the same area. Outdoors, spiders can be found everywhere. They’re most common under eaves, near lights and water – places where it’s easy for them to catch prey.
Webs are easily identifiable, as you will notice egg sacs inside the spider webs which look like small balls. You can find them in shades of white, yellow, and brown. Each egg sac can contain 50-500 baby spiders. Mother spiders are very defensive of their egg sacs; be sure not to disturb them. When egg sacs are removed, spiders will hatch out, spreading around the surrounding are, reaching full-size in 3-12 months.
Cellar spiders, also known as; daddy long-legs or granddaddy long-legs, are found in every continent in the world except Antarctica, where it’s too cold for them to survive. Their distinctly unique look is easily identifiable by their long, thin legs and body, found to be clear, clear brown, or gray. Cellar spiders create irregular web-structures, that don’t appear to be organized in any specific way. Cellar spiders wait for prey to get caught in their web and vibrate their body, so that the web blurs their vision. There is a myth that Cellar spiders have the most potent venom of any spider, but their fangs are either too small or weak to puncture the human skin; although their venom can be quite debilitating, it is not known to be lethally toxic to humans.
Black widows are certainly one the most well-known spiders. Western black widows, which surprisingly can be found in British Columbia, are extremely dangerous. The females have potent venom composed of neurotoxins, which is known to lead to fatalities with children and the elderly, however medical treatment may be required for anyone who has been bitten. They can be identified by their large black body, with an “hourglass” mark on their abdomen. This hourglass-shaped mark can be found in red, yellow, or white. The species build irregular messy webs, that have no apparent organization. Black widows are often found living in and around homes, usually in dark cluttered areas. They have poor eyesight, however, will act aggressively to anything that disturbs its web, as they detect danger by silk vibration.
