Common House Spiders in New Jersey

Most spiders found in NJ homes are harmless and feed on other insects — but heavy activity can signal another pest issue.

Signs to look for

• Webs in corners, basements, garages, and around exterior lights
• Egg sacs in undisturbed areas
• More spiders where other insects are present

Why it happens

Spiders follow their food. A rise in spiders often means there are other insects around the home for them to eat.

Prevention tips

• Reduce clutter and clear webs regularly
• Limit exterior lighting that attracts insects at night
• Seal gaps around windows, doors, and the foundation
• Keep basements and garages dry and ventilated

When to call a professional

If spider activity is persistent or paired with other pests, an inspection can address the underlying cause. Keera Pest Control serves Woodbridge Township and nearby Central New Jersey communities.
