The primary allergens in the state of Florida are ragweed pollen and mold spores, according to the Allergy & Asthma Specialists of North Florida, P.A. Although spring is typically known for being the heaviest allergy season, those suffering from allergies in Florida face high impact in the fall.
Grass and mold pollen allergies may extend well into November, largely due to the longer growing seasons in the warm climate, reports the Allergy & Asthma Specialists of North Florida, P.A. The primary cause of allergies is ragweed, which releases pollen in late summer and lasts until the first signs of frost. In Florida, frost is rare and as a result the pollen season extends longer than in other areas of the country. Proper weed control in the area surrounding one's house helps to manage the pollen levels.
Mold allergies occur in cool, damp areas, states the Allergy & Asthma Specialists of North Florida, P.A. Florida's humidity, mixed with cooler fall air, leads to increased mold growth. Mold spores tend to develop in decaying plant matter, compost piles and rotting wood. They also spread through the air in the same manner as pollen, however they don't die off with the onset of cold weather. They go dormant until warmer temperature arrives in the spring, and then reappear. Clearing leaves and compost piles, as well as replacing and removing rotting wood around or inside the home, helps to control mold spores.
