How to Safely Handle Black Widow Spiders in Your Home

Understanding Black Widow Spiders

Identification

Black widow spiders are easily recognizable by their:

• Glossy black coloring
• Red hourglass marking on the underside of abdomen
• Female size of about 1.5 inches (including legs)
• Body length of approximately 1/4 inch (6-8 mm)

Habitat

These nocturnal spiders prefer dark, secluded areas such as:

• Dark corners of garages
• Cluttered storage areas
• Under rocks or wood
• Basement window wells
• Outdoor furniture
• Dense vegetation

They build irregular, tangled webs close to the ground.

Safety Equipment and Precautions

Before attempting to handle black widow spiders, ensure you have:

1. Heavy-duty gloves
2. Long-sleeved shirt
3. Long pants
4. Closed-toe shoes
5. Protective eyewear

Additional safety measures:

• Use a Flashlight: When inspecting dark areas, use a flashlight to spot spiders from a safe distance
• Avoid Direct Contact: Never attempt to handle a black widow spider with your bare hands
• Avoid Touching Webs: While not venomous, touching webs can alert spiders to your presence

Removal Methods

Non-Chemical Methods

1. Capture and Relocation:

   • Place a clear container over the spider
   • Slide a piece of stiff paper underneath
   • Carefully flip the container right-side-up while keeping the paper in place
   • Secure the container with a lid
   • Release the spider at least 100 feet from your home

2. Vacuuming: Use a vacuum with a hose attachment to remove spiders and their webs. Ensure the vacuum bag is sealed and disposed of immediately.

Chemical Methods

• Insecticide Sprays: Use EPA-registered pesticides specifically designed for spiders
• Professional Pest Control: Consider for severe infestations

Prevention Strategies

Home Maintenance

• Seal cracks and crevices around windows, doors, and foundations
• Remove debris and woodpiles from around your home

• Maintain proper ventilation in dark spaces

Natural Deterrents

• Sprinkle diatomaceous earth in prone areas
• Use citrus or peppermint essential oils
• Keep your home clean and clutter-free

Lighting Considerations

• Use yellow "bug lights" instead of white lights outdoors
• Keep exterior lighting away from doors and windows
