7 days left of flower! big problem!

i am in the final week of flower before harvesting, and i have a winged root aphid problem and they're laying eggs on my frosty almost finished nugs. i read that the larvae can cause me bud rot, and with only 7 days left i want to try my hardest to save the grow. what can i do/use in these last 7 days to get rid of the bugs? and can the larvae really cause me bud rot this late in the game?

Snip snip

Wouldn't root aphids lay eggs in the root zone? They onlt get wings when thyre mature I thought.

Harvest time me thinks

:'( i'm gonna try heating up some habaneros in water for a half hour then straining and using the water as a drench and use tweezers to take any black speck or winged creature i see. ugh the buds were so close to being finished they still look about a week premature but if what i do today doesn't help anything then i guess i'll chop em

You have fungus gnats
