Are Black Widow Spiders common in spokane and north idaho?
Black widow spiders are present in Spokane and North Idaho, but they are not very common inside homes. Most sightings occur outdoors in sheltered areas like woodpiles, sheds, crawlspaces, and under decks. Compared to other spiders in Spokane, black widow encounters are relatively rare. Preventative exterior pest control can further reduce the likelihood of finding them near your home.
Black widow spiders do exist in the Inland Northwest, including communities like Spokane, Spokane Valley, Post Falls, Hayden, Rathdrum, and Coeur d’Alene. However, they are far less common than house spiders or hobo spiders, and most reported sightings occur outdoors rather than inside living spaces.

Are There Black Widows in Spokane?
Yes — black widows are native to Washington State and have been documented in the Spokane region. They prefer dark, undisturbed outdoor areas such as:
- Woodpiles
- Sheds and outbuildings
- Crawlspaces
- Under decks
- Rock retaining walls
- Outdoor storage areas
Black widows are not aggressive and usually bite only if directly disturbed or trapped against skin.
How Common Are Black Widows in North Idaho?
Black widows are less common in North Idaho than in warmer regions of the state but can still be found in dry, sheltered outdoor areas. In communities such as Post Falls, Hayden, Rathdrum, and Coeur d’Alene, most sightings involve:
- Wood storage areas
- Detached garages
- Outdoor storage bins
- Patio furniture
Indoor infestations are rare. Most spider-related pest service calls in Spokane and North Idaho involve common house spiders, not black widows.
How to Identify a Black Widow Spider
Identification Features:
- Glossy black body
- Round, bulbous abdomen
- Red or orange hourglass marking on the underside
- Irregular, messy web (not symmetrical like orb-weaver webs)
Juveniles may appear brown or tan before turning fully black. If unsure, avoid handling the spider and have it identified professionally.
Are Black Widow Bites Dangerous?
Black widow venom is medically significant, but serious complications are rare in healthy adults. Symptoms may include:
- Muscle pain or cramping
- Sweating
- Nausea
- Localized swelling
- Abdominal discomfort
Children, elderly individuals, and people with compromised immune systems should seek medical care if bitten. Most bites occur when reaching into dark, undisturbed spaces.
Why Black Widows Are Rare Inside Spokane Homes
Spokane’s colder winters limit large black widow populations. They prefer:
- Warmer microclimates
- Protected outdoor environments
- Areas with consistent insect food sources
Modern, well-sealed homes are less attractive than cluttered sheds or wood storage areas. Regular exterior pest control treatments reduce insect populations, which also reduces spider activity.
How to Reduce the Risk Around Your Property
Homeowners in Spokane and North Idaho can lower the risk of black widow spiders by:
- Keeping firewood away from the home
- Sealing foundation cracks and gaps

Preventing insect populations near the home is an effective way to reduce spider activity.
