i had a plant full of worms I cut the top top main nugs and left the rest and sprayed heavily.. does the spray kill the worms pretty quickly or are they gonna keep fucking me
-how effective your spray is
-how bad they have infested thus far
-how bushy your plant is (if it's really compact you need to get in there and make sure you cover all problem areas well
all you can do is hope for the best. i haven't had personal experience with this, but have seen it on friends plants and they were able to hold them off til harvest.
