Lee from Herron, Michigan writes

Is NiBor-D Insecticide safe if earthworms are in the ground?

Also, as we are now inundated with the most cluster flies we've ever seen, when would be the best time to spread this to keep next year from being so bad?

Answer:

NiBor-D Insecticide can potentially harm earthworms that come in contact with it. Late Summer would be the best time to treat for Cluster Flies as they are the worst in the beginning of Fall.
