Why December Brings Increased Pest Activity in Columbus

As temperatures drop in Columbus, pests begin seeking warm, sheltered places to spend the winter. December is one of the busiest months for indoor infestations—especially rodents, spiders, and pantry pests. With holiday baking, food storage, and extra household clutter, homes become even more attractive to cold-weather invaders.

Ohio’s unpredictable winter conditions—snow one day, mild temperatures the next—create the perfect opportunity for pests to slip indoors unnoticed.

Most Common December Pests in Columbus

1. Rodents (Mice & Rats)

Rodents are the top winter pest problem in Columbus. They squeeze into homes through tiny openings, especially when nighttime temperatures drop below freezing.

Common signs include:

• Scratching or scurrying sounds in walls
• Droppings in basements, pantries, or behind appliances
• Chewed boxes, wiring, or insulation
• Nesting materials in storage areas

Rodents not only cause damage but also contaminate food and spread bacteria.

2. Spiders

Winter doesn’t stop spiders—they move indoors following other insects, which serve as their food source.

Where they hide:

• Basements
• Attics
• Closets
• Garages
• Corners of quiet rooms
  

Most household spiders are harmless, but increased sightings in December indicate other insects are already active indoors.

3. Pantry Pests

Holiday cooking and baking make December a prime time for pantry pests such as:

• Indian meal moths
• Flour beetles
• Grain beetles
• Weevils

These pests thrive in packaged goods like flour, cereal, rice, pasta, and pet food.

Why Pest Problems Spike Around the Holidays

• Extra food storage (flour, sugar, spices) attracts pantry pests
• Increased clutter—holiday décor, boxes, and bags create hiding places
• Frequent door openings let pests slip inside
• Heat from indoor spaces draws rodents and spiders
  

Columbus homes experience a perfect storm of warmth, shelter, and available food during December.

December Pest Prevention Tips for Columbus Homeowners

1. Seal Entry Points

Inspect the foundation, windows, doors, and utility lines for gaps. Mice can enter through openings as small as a dime.

2. Store Food in Airtight Containers

Use sealed bins for grains, baking supplies, and pet food to prevent pantry infestations.

3. Reduce Moisture

Use dehumidifiers in basements and fix any leaks. Moisture attracts insects—and spiders follow.

4. Declutter Storage Areas

Clear out garages, basements, and attics where pests love to hide.

5. Keep Holiday Items Clean

Before storing décor, inspect boxes for pests and use plastic containers instead of cardboard.

When to Call a Professional

If you’re hearing noises in the walls, finding droppings, or seeing pantry pest activity, it’s time to call a local Columbus pest control specialist. A professional can identify pest entry points, treat active infestations, and provide long-term winter protection.
