Visitors to Pigeon Lake Provincial Park, southwest of Edmonton, are being forced to contend with an army of visitors that are in the midst of a 'cyclical boom.'

Alberta Parks says, while they may be unpleasant to some people, they're mainly just a nuisance.

Alberta Parks says the caterpillars are in the midst of a population boom that occurs every 10 to 12 years.
