Product Q&A

Answer:

Spectracide Triazicide Once & Done Insect Killer Concentrate is not labeled for cluster fly larvae nor flies in general and we are not able to find any product that would work on the larvae.  I did find a Penn State article here that might help.  We also have a guide for How to Get Rid of Cluster Flies.
