Natural Hibernation and Overwintering

Yellow jackets, a type of wasp, are known for their social behavior and complex colonies. As winter approaches, these colonies typically undergo a process called “natural hibernation” or “overwintering,” where the queen and a few thousand worker wasps remain active to protect the colony’s food stores and young.

During this period, the queen yellow jacket will begin to slow down her metabolism, reducing her energy consumption and allowing her to survive on stored food and water. She will also start to prepare for the next year’s colony by feeding on nectar and pollen to build up her strength and energy reserves.

The queen yellow jacket will also start to produce pheromones, chemical signals that help the colony communicate and coordinate their activities.
This pheromone production helps the colony to maintain social cohesion and ensures that the queen is recognized and protected by the worker wasps.

As winter progresses, the queen’s pheromone production will slow down, and the colony will enter a state of dormancy, often referred to as “diapause.” During this period, the queen will remain in her underground nest, surrounded by her stored food and the bodies of her dead workers, waiting for the warmer temperatures and longer days of spring to return.

Wintering Sites and Habitat

Yellow jackets typically choose specific wintering sites and habitats to ensure their survival during the cold winter months. These sites often include:

Underground burrows and nests: Yellow jackets often dig complex networks of tunnels and chambers to protect themselves from extreme temperatures and predators.
Abandoned rodent burrows: Yellow jackets will often take over abandoned rodent burrows, which provide a safe and protected environment for the queen and her workers.
Tree cavities: Yellow jackets may also use tree cavities, hollow logs, or other natural openings to create a sheltered space for overwintering.
Man-made structures: In urban areas, yellow jackets may use man-made structures like attics, walls, or chimneys to overwinter.

When selecting a wintering site, yellow jackets consider factors such as:

Temperature: Yellow jackets prefer sites with consistent temperatures between 32°F and 50°F (0°C and 10°C), which allows them to conserve energy.
Humidity: Yellow jackets require a relatively high humidity level, typically above 50%, to maintain their skin and body functions.
Predator avoidance: Yellow jackets choose sites that minimize their exposure to predators, such as birds, bats, and other insects.

Practical Tips for Yellow Jacket Control

If you’re concerned about yellow jackets in your home or yard, here are some practical tips to help manage their populations:

Seal entry points: Caulk cracks and crevices around doors, windows, and vents to prevent yellow jackets from entering your home.
Remove food sources: Keep your home and yard clean, and avoid leaving food or sweet substances outside, as these can attract yellow jackets.
Use yellow jacket traps: Use baited traps or sticky traps to capture and remove yellow jackets from your home and yard.
Call a professional: If you’re dealing with a large or aggressive yellow jacket population, consider hiring a pest control professional to safely remove the colony.

In the next section, we’ll explore the importance of yellow jacket communication and how it affects their social behavior and colony dynamics.
