Thank you sir! The plant seems to be doing a little better today after I dusted it with BT dust yesterday evening.. I am still keeping my eyes on them both, checking for any further sign of pests and their eggs.It's possible I suppose but very very doubtful as I doubt the dust will penetrate deep enough into the soil as the dust is not soluble, whereas the liquid Bt is. The absolute best thing for grub worms are beneficial nematodes, the nematodes that come on a little blue sponge but not everyone sells them. They also come in a dried form but I have never had any luck with the dried nematodes.
