I have been told the Black eyed susan grubs work great for panfish. What time of the year (about what month) do you collect these and how do you keep them till the hardwater season?
Where on the Black Eyed Susan plant do you find these grubs?
Any replies would be greatly appreciated.

Never heard of these, perhaps they meant goldenrod grubs? There will be a gall about halfway up a goldenrod plant; harvest them after they turn brown, keep them in a cool place, When you need some bait, cut partway through the gall with a knife, then snap it in half; there will be a white grub inside. Keep the grubs in sawdust until ready to use. If the gall has a hole in it, that means the grub is alrady gone, no need to pick those.

Black Eyed Susans is the name of the fall flowering plant.
They have Yellow Daisy looking flowers with brown or black centers. They grow wild in clusters along rairoad tracks, highways, along fence rolls. The flowers come into bloom about this time of year. I know what goldenrod plants look like, these are not them. Google Black Eyed Susans for a visual.
I just not sure when to collect these or what to store them in?
I thought maybe someone uses these and also collects them for hardwater panfish.

I left the lid on my composter open for a day or two and then went back a couple days later and was able to collect all the spikes I could want. Gross and all but I probably have a thousand or more in the fridge (in saw dust) and they keep that way for a long time. I just hope the fly population next year doesn't explode.
