What @Sbeanonnamellow notes, Microbe-Lift BMC would be something to try. It is very concentrated and a small amount will go a long way. Or what @AzSeaindooin420 suggests.
For such a large number of plants probably a powered sprayer/fogger … deck yourself out in PPE.
This is safer than some of the alternatives and would be a good first assault. Worms are a much better problem to have to deal with than some of the even more destructive pests.
