Would this spray work?

Is it worth having this spray on hand in case of spider mites etc? Would it work with all the bugs that might decide to camp out in my grow tent?

I wouldn't use that stuff look for an organic Spinosad based spray Monterey gardens insect spray is omri listed witch mean you can spray it on food you intend to eat, or i believe azamax works good for spidermites good to take preventive measures as well and keep your plants clean of pests might consider changing between the two so they don't build up immunity
