Little black flies around the pot

Check whether the flies gather by damp soil or by fruit and drains.

What to check first

Fungus gnats are small, dark, weak fliers that often rise from the pot when you water. If most flies gather near fruit or a drain, look for another source.

What to do now

Empty the saucer and let the top of the mix dry between waterings as much as the plant tolerates. A yellow sticky card near the pot helps you track the adults.

What to watch next

Count whether you catch fewer adults over the next few weeks. If numbers stay high, check other damp pots too. Traps catch adults and leave the larvae in the mix.
