Expert Response
My first question is, are you absolutely sure you have a grub problem? Are there patches of grass which can be rolled up like a rug because they have no roots? I will give you a link to a rather long article we have on grubs but a 'grub problem' means finding 10 or more in a square foot of soil. Your Bioadvanced 24 hours will have taken care of any grubs and you applied it at the right time. There is no need for any more chemicals on your lawn.
Acelepryn insecticide provides long-lasting control of
Japanese beetles, leaf-feeding caterpillars, including eastern tent
caterpillars, fall webworm and bagworms, and sawfly larvae on ornamental plants, trees and shrubs. It is not meant for grubs. So, first of all, make sure you actually do have a problem. There is no need for more money to be spent on this. Any grubs that might have survived (and probably none) are now adults. https://extension.umn.edu/news/white-grub-control-lawns
