Gnats are small, flying insects often found in damp or decaying environments. They belong to various families, including fungus gnats, fruit flies, and drain flies. Gnats can become a nuisance when they invade homes, particularly in areas with excess moisture or organic matter. Their presence is typically linked to decaying plant matter, overwatered houseplants, or uncleaned drains.
Attracted to light: Gnats are often drawn to light sources, which is why you may notice them buzzing around lamps and windows at night. This behavior, known as positive phototaxis, makes them more noticeable in illuminated areas.
Feeding habits: Gnats are attracted to overripe fruit and decomposing organic matter. They feed on liquids, such as the juices of fruit or decaying materials, using their specialized mouthparts.
Breeding grounds: Gnats lay their eggs in moist environments where their larvae can thrive. Common breeding grounds include potted plants with overwatered soil, kitchen sinks, garbage disposals, and other damp areas.
Lifecycle: Gnats undergo a complete metamorphosis with four stages: egg, larva, pupa, and adult. The entire lifecycle can be completed in a few weeks, depending on environmental conditions, allowing for rapid population growth.
Seasonal activity: Gnats are most active during warmer months, particularly in late spring and summer. Their populations increase with higher temperatures and humidity, making infestations more common during these seasons.
