Common dude.. NOOOOO.. you dont have to kill everything, YES you have to spray the crap out the room, but you may try this before you become the MJ murderer.
INSIDE option: move the plants to another room, preferably close to a window and right before you move them spray them with a pesticide, i used OMRI products, they worked but the best bet was 90%iso alcohol with water, (HEAVILY DRENCHED to work), once sprayed move them to the new spot, Leavr there for about 3-5 days, if possible do an insect bomb in the grow area and then come back next day and bleach the area, how clean you wanna go is entitled up to you, but i would scrub with bleach at least on 2-3 different days just to catch the ones missed before..
Now that your grow area is clean go back to the plannts and with your hands rub more alcohol with water throught all the leaves, let sit 15 mins and repeatr again, then you can move them back to their growing area.
This process might require more than just regular patience but is well worrth it if you dont want to kill those plants.. Good Luck.. :aok:
