Shore Fly Control

Shore flies don't bore into roots like fungus gnats, but they breed in algae-soaked media and speckle your foliage and fruit. Here's how to control shore flies at the source.

Shore fly larvae feed on algae in wet media where sprays don't reach. Shore fly biological control targets them at the larval stage so the breeding cycle breaks — knowing how to control shore flies biologically keeps fly specks off your crop, residue-free.

Why choose biological shore fly control

Biologicals attack shore fly larvae in the media, leave no residue, and are safe for crops, pollinators, and staff — while you fix the root cause by drying things out and cutting algae.

How to build your program

Apply beneficial nematodes to infect larvae and establish Dalotia rove beetles to patrol the surface. Improve drainage, avoid standing water, and reduce algae to remove the breeding sites that feed shore flies.

• NEMAforce SC / SF — beneficial nematodes that kill shore fly larvae in the media.
• DALOTIAforce — rove beetle that preys on larvae at the surface.

Frequently asked questions

How do you control shore flies?

Cut algae and standing water, then apply beneficial nematodes and Dalotia rove beetles to kill larvae in the media.

What's the difference between shore flies and fungus gnats?

Shore flies are stouter, stronger fliers with spotted wings that feed on algae; fungus gnats are slender and weak-flying. Both breed in wet media and respond to the same soil biologicals.

Are shore flies harmful?

They rarely damage roots but spread fly specks and pathogens and signal excess moisture and algae that need correcting.

What kills shore fly larvae?

Beneficial nematodes and predatory rove beetles target the larvae in the algae-rich media where they develop.
