Hello I have a question on harvesting sunflower seeds. This is my first time harvesting for roasting. I had picked the head and let it hang for several days it is now green yellow with seeds starting to fall out. I decided to harvest the seeds for roasting, but I noticed many of the seeds had holes and little reddish larvae were crawling out along with these miniscule red beetles. Is this batch a bust? Or can I still pick out the undamaged seeds for roasting? Thank you.
