We're seeking a pollen partner in Louisiana.
PollyMap doesn't publish cheap forecast estimates — the kind that guess what might be in the air and are often wrong by the time you read them. Every report on PollyMap is real airborne pollen and mold, captured by a PollyKit air sampler and counted under a microscope by a trained local partner.
We're actively seeking an allergy clinic or qualified collector to become the Official PollyMap Partner for Louisiana. Exclusive territory, weekly content, and AI-assisted analysis included.
Pollen patterns across Louisiana
Oak, pine, cedar, and pecan create an intense, early spring tree season — sometimes coating cars in yellow pine pollen by March. Bermuda and Bahia grass pollinate from late spring through fall, and ragweed dominates the late-summer weed load.
