Mold and Mildew

Florida’s warm, humid climate can bring an unexpected guest: mold and mildew. These common fungi thrive in our subtropical environment, especially in shared spaces like university Residence Halls where moisture from showers, AC units, and even rainy days can build up quickly. Knowledge is your best defense! This guide breaks it down simply: what they are, how they sneak in, easy prevention steps, and where to turn for help. With a few habits, you can keep your space fresh and focus on what matters—making friends, acing classes, and enjoying Sailfish life!

Mold and mildew are types of fungi that are naturally everywhere—outdoors on leaves and indoors in tiny spores floating in the air. They’re part of nature’s cleanup crew, breaking down organic matter, but they become a problem when they grow indoors.

• Mold: Fuzzy or slimy patches in colors like black, white, green, or brown. It often smells musty and grows on walls, ceilings, or fabrics.
• Mildew: A powdery surface growth, usually white, gray, or yellowish, that loves damp spots like shower curtains or windowsills.

Most people aren’t bothered by small amounts of mold and mildew, but in those who have allergies, asthma, or a weakened immune system, even minimal levels can trigger sneezing, coughing, itchy eyes, or worse. The good news? You can’t eliminate them entirely, but controlling moisture keeps them in check.

Florida’s humidity—often 70-90% year-round—creates the perfect storm for mold and mildew. They need three things to grow: mold spores (always around), a food source (like dust, paper, or drywall), and moisture. In Residence Halls, here’s how it happens:

• High humidity + poor ventilation: AC units fight it, but if vents are blocked or fans aren’t used, moisture lingers.
• Daily habits: Steamy showers, wet towels on the floor, or damp clothes in closets trap humidity.
• Water issues: Leaks from pipes, windows, or roofs—common after Florida’s frequent rains or storms.
• Overcrowded spaces: Piled-up laundry or cluttered storage reduces airflow, letting spores settle and multiply.

In short, staying on top of moisture is vital in the sunshine state!

Prevention is easier (and cheaper) than cleanup. Aim to keep indoor humidity below 50-60%—use a cheap hygrometer from a store to check. Team up with your roommate for these habits:

• Run the AC wisely: Set thermostats to 70-74°F and keep the fan on “AUTO” for steady dehumidifying. Close windows to block humid outdoor air.
• Shower smart: Use the exhaust fan during and after showers. Leave the bathroom door cracked (or open in suites) for 15 minutes to vent steam. Wipe down wet surfaces.
• Dry everything fast: Hang towels and clothes to air-dry fully (24-48 hours max). Store wet items in a sealed bin until laundry day.

• Keep it clutter-free: Don’t block vents or overpack closets/under-bed storage—air needs to flow!
• Clean surfaces: Wipe down furniture, counters, and bathroom fixtures with bleach-based cleaners or vinegar. Vacuum floors and empty trash regularly.
• Food and spills: Store snacks in the fridge and clean up messes right away to avoid attracting more moisture.
• Pro tip: In Florida’s heat, a small dehumidifier or DampRid bags in closets can be a game-changer for extra humidity control.

Spotted a fuzzy patch or musty smell? Act fast —small spots are often fixable.

• Clean small areas (<10 sq ft): Scrub with hot soapy water, diluted bleach (1 cup per gallon), or mold-killing cleaners like vinegar. Never mix bleach with ammonia! Dry thoroughly with a fan.
• Check the source: Look for leaks or condensation—report it.
• Report bigger issues: For larger spots, water damage, or if it keeps coming back, reach out to a Reslife Staff  (AC, RA, Reslife Office) to submit a maintenance request ASAP. PBA staff will inspect and handle remediation to keep everyone safe.
• Health concerns? You can visit our Sailfish Health page for instructions on how to access the TimelyCare app to connect with licensed medical providers.

Remember, ongoing issues usually mean a moisture problem—address that first to stop regrowth.
