How To Identify And Treat Spiders In Boise

March 20, 2022

Many strange spiders will unexpectedly appear in homes spinning webs and hunting prey. Spiders are predatory arachnids that have eight legs and have fangs (chelicerae) that can deliver a venomous bite.

Did you know that arachnology is a field that is specific to the study of spiders and various other arachnids? Research suggests that most types of spiders are unlikely to pose serious health risks to humans.

Spider Species In Boise

The Boise area is home to some dangerous types of spiders, such as the black widow spider and the hobo spiders; however, the majority have much less potent venom that poses minimal risks to human health. Some of the common types that you may notice inside a home include funnel-web spiders, orb weaver spiders, jumping spiders, and cellar spiders, which are often referred to as “daddy long leg” spiders.

Are you wondering who eats spiders when it comes to the animal kingdom and if they will limit the number of potentially dangerous spiders that are found in homes? Yes. Creatures that commonly consume spiders include birds, wasps, toads, lizards, and a host of other carnivores, many of which can potentially be considered pests. Also, spiders are known for cannibalism, as females will often feed on male spiders.

The Most Dangerous Spiders In Boise

Three of the most dangerous types of spiders found in this region include the black widow, hobo spider, and yellow sac spider. Although the brown recluse spider is a potentially dangerous type that is prevalent in many areas of the U.S., they are rarely seen in Idaho.

  • The black widow: The black widow spider has a shiny, black body with long legs that measure approximately 1.5 inches in diameter. They are recognizable because of their reddish “hourglass-shaped” marking on their belly
  • The hobo spider: Believed to have originated in Europe, the hobo spider was first noticed in Idaho during the 1960s and remains most common in the northwestern states. The hobo spider typically appears in shades of brown or tan with a greyish underside and yellowish markings.
  • The yellow sac spider: With a yellowish appearance, the yellow sac spider builds “silky sacs” that are used for placing eggs, resting, and hiding. They are among the most likely to bite humans in this region, which commonly causes pain and itchiness.

The Best Way To Handle Spiders In Boise

Use a vacuum or other tools for promptly removing spider webs indoors to discourage them from staying. Avoid intentionally making contact with spiders to limit the possibility of experiencing a spider bite.

Prevent Future Spider Infestations In Boise Homes

Perhaps there is another pest who eats spiders that can be used to control the population? Although birds and various reptiles are among the most common predators that target spiders, they are unlikely to create a noticeable decline in the spider population in your yard. The two most effective ways of preventing these creatures are to limit the insects that they prey on and to employ measures for physically excluding them from entering the home.

Turn off bright outdoor lights, particularly those near exterior doors, when they are not needed to prevent flying insects from congregating. Consider switching to the “yellowish” LED bulbs that have proven to be less attractive to many pests.

Closely inspect the property exterior for any potential entry points. For example, repair damaged window screens, fill cracks and crevices near the foundation and install sweeps on exterior doors.
