Boise has so many great homes and businesses. Unfortunately, spiders like to move right on in and make Boise homes and businesses their permanent place of residence. Spiders can be seen everywhere from the Boise Greenbelt to the Aquarium of Boise. Without using a professional Boise spider exterminator, your chances of experiencing a spider infestation will be will quite high. Black Widow: Black Widows are identified by their shiny black color with a bright red hourglass shape on their back. They are typically 1 1/2 inches to 1 3/8 inches long. They have a venomous bite that is said to be 15 times more venomous than a rattlesnakes bite. A Black Widow bite may cause nausea, difficulty breathing and muscle aches. Hobo: Hobo spiders are varying shades of brown with a dark stripe. They are 1 inch to 1 3.4 inch in diameter, including legs. There is some debate about the potency of a hobo spider’s venom. Either way, you probably don’t want a bite from one of these spiders. House Spider: True to its name, the house spider often invades homes. Adults can live for a year or more. A female can lay up to 17 egg sacs, or 3,760 eggs in her lifetime. They are a yellowish brown color with white and dark stripes. They are 1/8 of an inch to 5/16 of an inch in length. These spiders may bite in defense, but are not generally considered medically threatening. If you need a Boise Spider Exterminator in your home or business, give Get Lost Pest Control a call!

Important Considerations:

  • Hobo Spiders are known to bite in defense
  • Males roam from June to October in search of a mate, so you are more likely to come across one during these months.
  • Hobo Spiders build funnel webs with an escape tunnel into a crack or crevice to hide in.


Where to Find Them on Your Property?

Hobo Spiders are not good climbers, so they are often found on the ground level or basement in a home. They like dark, moist areas and can also be found in window wells and crawl spaces.
