Regular cleaning and vacuuming also help remove spider webs and egg sacs. Maintaining tidy storage spaces dramatically reduces spider presence.

Lighting alone will not eliminate spiders but helps reduce their preferred living conditions. It is an easy addition to a comprehensive pest prevention plan.

Pros

Pros

• Household item
• Easy mix
