I added FHM and BG to my new forage pond/wetland/sediment pond after swarms of mosquitoes invaded during last winter and thousands of larva were observed swimming. I think it worked. My vote is toward adding FHM ASAP. Why not?
The bullhead fry just as likely could've been responsible for eating the larva...are you at risk of anything washing in?
How are you going to know unless you try!
