Winter Spiders: Facts vs Myths – Brown Recluse & Black Widow ID and Safe Control in Rolla, MO

🕸️ Winter Spiders: Facts vs Myths

Myth 1: All spiders die off during winter.
Fact: Many spiders, including the brown recluse and black widow, survive the cold by sheltering indoors in basements, attics, and crawl spaces.

Myth 2: Brown recluse spiders are found in every home.
Fact: While common in Missouri, the brown recluse prefers dark, undisturbed places. Not every spider you see indoors is a recluse.

Myth 3: Spider bites are always dangerous.
Fact: Most spiders are harmless. However, identifying venomous species is key for safety.

Brown Recluse Spider Identification

The brown recluse is one of Missouri’s most misunderstood spiders. Here’s how to spot one correctly:

• Color: Light to medium brown with a distinctive dark violin-shaped marking on its back.
• Size: About the size of a quarter (including legs).
• Eyes: Six eyes arranged in pairs (most spiders have eight).
• Behavior: Prefers hiding in cardboard boxes, closets, basements, and behind furniture.

Brown recluse bites are rare but can cause tissue irritation or necrosis. If bitten, seek medical attention and contact a pest control professional for inspection.

Black Widow Spider Identification

The black widow is another venomous spider that may seek warmth indoors during Missouri winters.

• Color: Shiny black body with a red hourglass marking on the underside of the abdomen.
• Web: Irregular, messy webs in garages, crawl spaces, and sheds.
• Behavior: Shy and non-aggressive unless provoked.

While black widow bites can be serious, they are rarely fatal. Prompt medical treatment is essential for safety.

Safe Control & Prevention Tips

• Seal cracks and gaps around doors, windows, and foundations.
• Declutter storage areas — cardboard boxes attract spiders.
• Shake out clothing and shoes stored in dark spaces.
• Install door sweeps and repair torn window screens.
• Use sticky traps to monitor spider activity.
• Schedule professional pest inspections during winter to detect hidden infestations early.
