In Theodore Dalrymple's The wilder shores of Marx on page 39 we find this reference:
"Indian or African airports ... with their pullulating chaos of officaldom, passengers, relatives, touts, ..."
Pullulating, from a Latin word that also gives us pullet means
1. Putting forth sprouts or buds; germinating. 2. Breeding rapidly or abundantly. 3. Teeming or swarming
In his novel Metroland Julian Barnes refers to
"the pullulating mass of the working class, who any moment might swarm like termites up the viaduct"
It's also in London Fields by Martin Amis
"This meant sitting about in a bijou flatlet in Cheapside, trying to keep tabs on the proliferating, the pullulating hydra of Clinch money".
