Fruit fly or vinegar fly
- One of the smallest flies found indoors, around one-eighth of an inch
- Typically enter homes during fall harvest season, when outdoor populations are high due to ripening fruits
- Prevention tip: Remove overripe fruits and vegetables. Rinse recycling materials to eliminate bits of soda or beer, which can ferment and provide breeding areas for fruit flies.
- Small, black-colored fly (up to one-eighth of an inch) often seen buzzing along windows and near houseplant soil when you water
- Larvae feed on fungus and organic matter, including plant roots, in potting soil
- Frequently enter homes in fall when houseplants are brought indoors after spending the summer outside
- Prevention tip: Reduce watering frequency for houseplants and allow soil to dry between waterings. Don’t let plants sit in water; don’t allow water to sit in drainage dishes. For severe outbreaks, use Bayer Advanced 12 Month Tree & Shrub Protect & Feed II.
