Nothing related with pesticide is listed on rack in Home Depot. I will check with Canadian Tire to buy it. Hope it is helpful to kill grubs. Thanks all for your suggestions.

Grubout. Don't ask for pesticide, it is a general name and most of them are now forbidden.

I went to Canadian Tie and be told Grubout is pesticide and not allowed to be sold even there is in stock. Now I am wondering whether humans are stuck by insect or animal.
