Spider Season

Fall is the worst month of the year when it comes to spider infestations in the PNW. Climate and mating season come together and encourage spiders to come out of their nests and invade all nooks and crannies of our homes. This is when spider pest control becomes a must.

According to Rob Crawford, spider specialist at the Burke Museum, spiders are reaching adulthood in late Summer and early Fall seasons. They begin to crawl out of their nests because they need more space for their webs. Mature males start wandering into the open by the dozen, trying to find partners — and scaring people of all ages.

In addition, spiders are getting bigger each year. Extended cool periods, combined with constantly fluctuating weather seem to be the cause for the family-sized spiders that are bound to invade all parts of our home.

So, what can we do to prevent them from invading our homes?

Preventing Infestations

Spiders are similar to other pests because of the conditions they need in order to thrive. Dark, moist areas provide prime breeding and nesting grounds. Additionally, these areas usually house bugs and other insects, which eventually turn into spider food.

Keep your house as sealed as possible. Cracks found around windows, foundations, plumbing fixtures, and doors usually attract and harbor insects. These, in turn, invite spiders and create the perfect spot for them to develop into the giants we now see.

If you did not have a chance to seal off all cracks and humid areas, you can still take preventive actions to stop spiders from appearing in your house. Organize your belongings and maintain a clean, clutter-free zone around your house. Wiping away any and all cobwebs as soon as you see them will discourage spiders from building them in the same place, forcing them to move away. Finally, trim the plants that are surrounding your house, and leave a gap between all plants and your house walls.

Identifying the Spiders

Fall is upon us, so chances are you will start encountering spiders around your house very soon. There are many spider species in the Pacific Northwest. Most of them are harmless, however, there are four species you should be able to identify right off the bat. These are yellow sac spiders, brown recluse spiders, hobo spiders and the dreaded black widow. They are all very poisonous to humans, and their bites can cause grave health complications if not treated on time.  

Yellow Sac Spider: Funnily enough, yellow sac spider are not usually yellow but a dark brownish color. They are often found in Eastern Washington and Greater Seattle Area. Yellow sacs are nocturnal garden spiders, but can wander indoors during mating season. Bites are rare and quite painful, causing swelling, broken blisters and slow healing wounds.

Brown Recluse Spider: Brown recluse spiders have starred in many Youtube horror videos, and are very common in the PNW. Again, don’t let the name fool you as these spiders can range from light yellow to dark brown in color. They can be identified by their eyes and violin-shaped mark on their thorax. Bites are not particularly painful, but can cause necrosis or rotting tissue in some cases.

Hobo Spider: Hobo spiders are said to be more aggressive than other spiders, although no study backs up the claim. Their venom also cause necrosis, and they are usually found on the ground because they are not great climbers.

Black Widow: The mythical black widows are the symbol of all venomous spiders. Their bodies are about half an inch long, with a red or white marking on their shiny black body. The most singular marking is the red hourglass-shaped marking on the underside of their abdomen. Black widows are not very nimble, so bites are rare. However, bites can be deadly for the elderly and children, so they must be handled with extreme care and precaution.
