Vespula germanica queens are typically polyandrous.
The queens mate with a moderate number of males, usually between one and seven, with no optimal number of mates.
In addition, mating events are independent of each other, which discredits the hypothesis that queens terminate mating behavior after mating with a male that possesses an optimal set of attributes.

V. germanica workers are unable to mate and so incapable of producing diploid offspring.
In some nests, however, the workers produce male offspring.
Worker reproduction has been documented in other Vespula wasp colonies, but usually only after the death of the queen.
However, workers of V. germanica have been found reproducing in the presence of a queen.
