Anybody know how many new queens an average nest produces for overwintering? There's a nest in our walls somewhere and I must have killed at least 10 that I'm assuming are queens because they considerably larger than the workers I've been seeing.
It's a lot more then I would have imagined. I hope your nest isn't a big one. Check it out - (even if only a third of them were queens, it could be 3,000 to 5,000 of them!).
Life cycle and habits
Yellowjackets are social hunters living in colonies containing workers, queens and males. Colonies are annual with only inseminated queens overwinterOverwinter

ing. Fertilized queens occur in protected places as hollow logs, in stumps, under bark, in leaf litter, in soil cavities and human-made structures. Queens emerge during the warm days of late spring or early summer, select a nest site and build a small paper nest in which eggs are laid. After eggs hatch from the 30 to 50 brood cells, the queen feeds the young larvae for about 18 to 20 days. Larvae pupate, emerging later as small, infertile females called workers. By mid-summer, the first adult workers emerge and assume the tasks of nest expansion, foraging for food, care of the queen and larvae, and colony defense.
From this time until her death in the autumn, the queen remains inside the nest laying eggs. The colony then expands rapidly reaching a maximum size of 4,000 and 5,000 workers and a nest of 10,000 and 15,000 cells in late summer. At peak size, reproductive cells are built with new males and queens produced. Adult reproductives remain in the nest fed by the workers. New queens build up fat reserves to overwinterOverwinter

. Adult reproductives leave the parent colony to mate. After mating, males quickly die while fertilized queens seek protected places to overwinter. Parent colony workers dwindle, usually leaving the nest and die, as does the foundress queen. Abandoned nests rapidly decompose and disintegrate during the winter but can persist as long as they are kept dry but are rarely used again.
Between the ones we've whacked with the swatter, trapped in a soap cup, and just died, the number is probably in the thousands. Hopefully there aren't a whole lot left.
One can only hope they start dying soon, but this fall is warm so far.
