I went to John Deere Landscape the other day to see if they had something cheaper to spray for grubs, ticks, fleas, etc.. I had been spraying Sevin XLR and got good results with it, but the cost per 1000 sq.ft. was high. He said that Crosscheck got the fleas, ticks, flies, mosquitoes better and cheaper. I seen that grubs was not listed but he said it would get them also. I have sprayed a few lawns already but for some people, the grubs is the most important insect they want sprayed for. Am I messing up, thinking that it will kill grubs.
