Plz HELP..Worms?

okay so this morning i went outside and took a big look on my 4ft TW plant and i saw that one of the colas had a diferent look... so i took a closer look and seen inside of the nugg and it had about 30-40 lil egg lookin' things w/ a catepillar or worm on it.. then i went ahead and looked around on other colas and it seemed to have the same stuff going on.. what can i do?... i have the 3-1 spray solution.. but my plant is in its 5 week of flowering and i dont know if its a good idea or not... but i don want to loose out n it.. plz help.. thank you

they are probably bud worms, but i have never used a spray to kill them, i just try to get something skinny to poke through the nug(piece of pinestraw)and clear out the webbing which usually makes the budworm come out on the other side of the nug where my fingers are waiting to squash him.
