Explore Bella’s Exterminator’s guide to spiders, the eight-legged inhabitants that coexist with us but can become a concern when their populations grow. This page aims to help you identify common spiders in the Glendora, California area and provides tips for effective control.

Spiders play a crucial role in controlling insect populations, but certain species can trigger concerns due to bites or infestations. In Glendora, you may encounter a variety of spiders, including the black widow, brown recluse, and common house spiders.

Habitat And Behavior

Understanding where spiders thrive is essential for effective control. Common house spiders prefer indoor environments, while black widows may be found in sheltered outdoor areas. Brown recluse spiders often inhabit undisturbed areas like closets and basements.


  • Black Widow Spider: Shiny black with a red hourglass shape on the abdomen.
  • Brown Recluse Spider: Light to dark brown with a distinctive violin-shaped marking on the cephalothorax.
  • Common House Spider: Small, light brown, with various markings. Builds webs in corners and undisturbed areas.

 Signs of Infestation:

  • Presence of webs in corners, windows, and other undisturbed areas.
  • Frequent sightings of spiders indoors.
  • Signs of spider bites (if applicable).


  • Keep the home clean and clutter-free to eliminate hiding spots.
  • Seal cracks and gaps in doors and windows.
  • Regularly clean and dust corners and other spider-prone areas.

Treatment and Control:

For general spider control, regular cleaning and removal of webs may suffice. However, if you’re dealing with potentially dangerous species like black widows or brown recluses, it’s advisable to contact Bella’s Exterminator for professional assistance. Our team is experienced in identifying and safely addressing spider infestations.

Common Misconceptions

Not all spiders are harmful, and many are beneficial in controlling other pests. Knowing the difference between harmless and potentially dangerous species is crucial.
