Killing maggots in soil of outdoor Carolina jessamine
After cleaning up large vine I put bag of organic soil around base. As spreading around I discoverered the maggots.
Maggots would be there for rotting animal matter. Ants or termite larvae would be present in decaying wood and vegetative matter. There may not be a need for control other than the clean up. Leave it open for birds to come in, or let the chickens in to have a feast if you have any.
