Florissant's French colonial origins date to the 1780s, making it one of Missouri's oldest continuously occupied communities. The settlement that became Florissant served as an agricultural village supplying the trade economy centered on St. Louis across the Missouri River bottoms, and the pattern of community development that began in the colonial era was formalized through the 19th century in a layout that survives in Old Town Florissant's preserved historic district — the churches, stone buildings, and street patterns that predate the postwar suburban development that surrounds them.

The postwar Florissant — the suburban expansion that grew the city from a few thousand residents to over 50,000 by the 1970s — produced the middle-ring suburban housing stock that now makes up the majority of the city's residential landscape. Homes built in the 1950s, 1960s, and 1970s on the north county clay soils, with the slab and crawlspace foundations of that era's construction, carry the maintenance profile of their age and vintage.

North County Pest Profile

Florissant's older housing stock — the 1950s–1970s construction that dominates the residential landscape — is in the maintenance window where original pest management infrastructure has aged significantly. Termite pressure in homes that lack recent treatment history is a consistent finding in north county inspections. The clay soils that retain moisture and the established tree canopy that many Florissant neighborhoods carry create conducive conditions for subterranean termite activity that warrant annual monitoring.

Florissant's creek drainages — the tributaries of the Missouri River that run through north county — create the mosquito breeding habitat and the wildlife corridor that bring deer, raccoon, and woodland pest species into the residential fabric.
