Insect control

Asked August 23, 2017, 10:25 PM EDT

My South facing lawn is under attack by insects. I bought Diazinon which says to apply it differently for surface bugs than for underground insects. Do I need to know for sure or can I apply it in the morning and then water it in in the evening? I don't want to make a mis-diagnosis. Thank you.
