Azamax spray will kill an infestation, but it's a battle. I personally HAVE NOT USED this produduct but have seen gardens that use it.
I "prevent" with mixture of water, ProTek, neem oil, sns209, I spray my plants fully drench my soil in it every 20is days from the start, up to 30ish days before harvest.
But, I grow indoors not out, so I have less bugs to deal with
Also, ONLY SPRAY NEEM OIL AT DARK, , it will burn the heck out of your plant.
Best of luck battling the super outdoor bugs
