fly control... dangerous?

[RunnerDucks]

I ordered maxforce fly killer to help control this fly issue that is getting out of hand. I saw someone on BYC say that it has been a great help to them and they would never be without it, so I jumped on it.
Now I'm worried.... what happens if my ducks eat the flies that were killed by this stuff? Is that likely to harm them?

I have no idea, but you could contact the manufacturer, and/or an avian vet. if you have access to one. Does it give you any information on the bottle (warning: do not ingest) or something..... Also, if you could contact the poster who recomended it you may be able to get additional information from them. Good luck!
