| Oct 30, 2025
When winter sets in across Waynesville and St. Robert, Missouri, many pests go dormant — but not spiders. These eight-legged creatures are resourceful, finding warmth inside homes, garages, and crawl spaces. Some, like the brown recluse and black widow, can pose serious risks if left unchecked. Let’s uncover the truth behind winter spider myths and how to keep your home safe this season.
Myths & Facts About Winter Spiders
Myth 1: Spiders die off during cold weather.
Fact: Most spiders, including brown recluses and black widows, don’t die — they relocate indoors where it’s warm and dry.
Myth 2: Every spider indoors is venomous.
Fact: Most indoor spiders are harmless. Only a few species, like the brown recluse and black widow, require special attention.
Myth 3: Spider bites are common in winter.
Fact: Bites are rare. These spiders are reclusive and prefer hiding over contact with humans.
How to Identify a Brown Recluse
Known for its distinct violin-shaped marking, the brown recluse is one of Missouri’s most recognized spiders. Here’s how to identify one:
- Light brown or tan body with a darker “violin” pattern on its back.
- About the size of a quarter, including legs.
- Has six eyes arranged in pairs, unlike most spiders with eight.
- Prefers undisturbed areas like basements, closets, and cardboard boxes.
The brown recluse isn’t aggressive and typically bites only when trapped or disturbed. Still, it’s best to contact a pest control professional if you suspect an infestation.
Identifying the Black Widow
The black widow spider is another species that sometimes appears indoors during the colder months.
- Shiny black body with a red hourglass shape on the abdomen’s underside.
- Builds irregular, messy webs in sheltered spaces like garages or sheds.
- Shy by nature but will defend itself if provoked.
Though their venom is potent, black widow bites are rare and treatable. Medical attention and professional pest control are recommended for safety.
Tips to Prevent Winter Spider Problems
- Seal gaps and cracks around windows, doors, and foundations.
- Keep clutter to a minimum in basements and garages.
- Store firewood and boxes away from living areas.
- Use door sweeps and replace torn screens to block entry.
- Schedule winter pest inspections to detect hidden infestations early.
