Yellow Jacket’s Life Span begins in the annual colonies where inseminated young queens wait through the winter in protected locations in stumps, logs, under barks, inside stacked up firewood, etc. Some yellow jacket queens take refuge in attics of homes and inside old barns. The early warmth of spring brings out the Yellowjacket queens from their hibernating places. They can be seen actively looking for perfect nesting sites as early as March. Initially the inseminated queen builds a paper nest comprising of tiny cells. The paper nest is made by chewing up wood in the located nesting site and lays eggs inside each cell of the nest. Yellow Jacket’s Life Span varies between the Queen and the workers. The Queen lives for a year where as the poor workers live for just 10 days (min) and 22 days (max)
The Life Cycle of Yellow Jacket Begins

The eggs hatch and the queen feeds the larvae for about 3 weeks. The larvae then pupate and emerge as adult female sterile workers. Once the workers emerge, they take care of the brood, feeding and defending the nest and also helping in expanding it to facilitate more cells for the queen to lay eggs. The queen hardly ventures out once the first batch of workers emerges. The colony keeps growing as workers readily feed the larvae and their queen with insects, nectar and other foods that are rich in protein.
Peak time of the Yellow Jacket Colony Activity – Winter Time
The colony is at its peak in the months of August and September when the queen lays the reproducing eggs. The eggs hatch and pupate to bring out young queens and males that mate. The males die soon after they mate and the inseminated queens take refuge in safe places to ensure that the reproduction cycle is carried on for the next year where they build independent nests and breed their young. The abandoned nests decompose and wither during the cold winter days. Some nests that stay put become homes for spiders and other insects that seek shelter from the cold. Come spring the Life cycle starts all over again.
