I have had this problem in fox farm ocean forest before. They do eat the roots bad and fast. I got rid of them by mixing 4parts water to one part hydrogen peroxide (get the stronger hydrogen peroxide it comes in two percentages)then just water your plants with that be sure to get them wet thruout. Your soil will fizz a little bit as it works but it does work. Won't hurt your plants at all. I had to treat mine several times thruout the grow Neems oil does nothing to the larvae or the adults but the yellow sticky things will get loaded with them. :smokebuds::karma Cloud::Hope this helps best of luck
