Thank you for your question.  Looking online I found Scotts Grubex (Chlorantraniliprole = active ingredient) and Scotts Grubex2 (Imidacloprid = active ingredient)
Both Chlorantraniliprole and Imidacloprid are preventive insecticides for white grubs in the soil.  They are intended to kill newly hatched grubs in late July-August.  They are not effective on mature grubs in April-May as the grubs cease feeding and pupate by mid-May.  I recommend using the grubex containing Chlorantraniliprole because it is less toxic to bees.  Chlorantraniliprole is also slower to dissolve in water so it can be applied earlier (mid-April to mid-May).  Bookmark the following link to refer to in the future:

A well-maintained lawn (fertilized, irrigated, mowed high...) can tolerate 5 grubs per sq ft without looking damaged. Please understand that ZERO grubs in a lawn is an unrealistic and expensive goal and an excessive use of chemicals which is harmful to the environment.
Instructions on how to check for grubs are in the first link above.
I would also recommend doing a soil test to determine the soil fertility this spring. Knowing the type and fertility (pH, macro-nutrient levels, CEC, etc.) of your soil is the starting point to establishing & maintaining a strong/thick turf that can resist diseases, weeds, moss and insects/grubs and look great without wasting material or $. More info here: Don't Guess-Soil Test-MSU and MSU Home Soil Test-self mailer Soil test results will identify any fertility concerns that you can work to correct, to improve turf health (it’s a well spent $26). Your report will provide recommendations to correct any deficiencies found, fertilizer type and a fertilization schedule (amount and timing) based on your preferred maintenance level (high, moderate or low).
