Shore Flies
Scatella stagnalis
Overview
The Shore Fly (Scatella stagnalis) is a common nuisance pest in nurseries and is often confused with Fungus Gnat.
Shore flies are bigger and more robust than fungus gnats and look like a smaller version of a normal house fly. Shore flies have clearly visible light spots on their wings and red eyes. They lay their eggs in moist growing media and algae.
Why you need to control Shore Flies
Shore fly larvae feed on algae and are generally not associated with any damage to seedlings.
However, shore flies may affect the aesthetic appearance of your plants by leaving faecal droppings (flyspecks) on flowers and leaves.
Beneficial predators to control Shore Flies among crops
You can control shore flies through a combination of cultural and biological practices.
Since overwatering, organic growing media, overfertilisation, and poor site hygiene encourage shore fly activity, it is a good idea to address these problems first.
Biological Services sells products to help you control shore flies such as Dalotia predatory beetles and yellow sticky traps or rolls which you can use to monitor and mass-trap the pests.
