Q.grub worms
We are infested with grub worms. My husband treated with specticide last Sunday but now our yard is covered with them. Do you think they are dying or do we need to treat again. HELP. Thanks.

Because grubs are subsurface insects, it might take a couple of days to completely control them. You may opt to repeat an application of spectracide per the product's specifications if you do not see some modicum of improvement over a reasonable amount of time or try another product altogether.
In the meantime here is an article on grub removal that might give you some other ideas:
