Fungus Gnats in South Florida

Fungus gnats are small, mosquito-like flies that are common pests in South Florida, particularly in indoor environments with houseplants or in greenhouses. While they don’t bite humans, they can be a significant nuisance and may damage plants. Dade Pest Solutions specializes in identifying and eliminating fungus gnat infestations to protect your plants and maintain a pest-free environment.

Identification of Fungus Gnats

Physical Characteristics

• Size: Adults are about 1/8 inch (2.5mm) long.
• Color: Grayish-black bodies.
• Wings: Long, delicate wings.
• Larvae: White to clear body with a shiny-black head, about 1/4 inch (5.5mm) when fully grown.

Habitat and Behavior

• Preferred Environment: Moist soil, especially in potted plants, greenhouses, and areas with decaying organic matter.
• Breeding Sites: Females lay eggs in moist soil or organic debris.

Risks and Damage

• Disease Transmission: Larvae can transmit plant diseases such as Pythium, Phytophthora, and Fusarium.
• Nuisance: While not harmful to humans, large numbers of adults can be a significant annoyance.
