Stop Onion Root Maggots in Sets

Question

For many years I used a product I put in the row as I planted my sets. When I went to get a new container, there was nothing available and all the people I spoke with didn’t know what I was talking about. I was sold a product to put on the plant after it started to grow, but I find that the maggots are already at work. Is there a product I can buy to put in the ground with my sets? I would like to plant now, in April.
