I have root maggots in my garden soil. I randomly scooped a cup of soil from my garden today and did an inspection for the insect, and sure enough I found three of them very much alive. I have a small garden, 15 ft. x 12 ft. How do I treat the soil to get rid of them? I live in Newfoundland, Canada, so we are not ready as of yet to start the growing season.
