Maggot type worm in my onions
I have little maggot type worms that are killing my onions. How can I get rid of them before they kill more than the onions? Will watering the soil surrounding the unaffected onions kill these horrible little pests? Should I pull the remaining onions, replace the soil and start from scratch?
It seems that you have root maggots invading the onions.
