Bug problem!

My indoor garden is 35 Days old and until today has been insect free. The only new thing in the garden is a germination tray with AK-47 and AI germinating (about 1 week now) in soil plugs (are these where they may have come from?) anyways I have already removed the enclosed tray from the grow room to another space, I did check my garden and found a couple adult flying brown nat looking bugs and killed them. The tray has a few flying around inside it I know they will work their way out. Should I just avoid the worst and dump the tray or can I salvage this before it blows up? I have my first $150 worth of seeds germining

yeah i would get some neem oil possibly? someone confirm this for me?

My bro helped me put together some organic tabacoo solution earlier today problem solved. got their asses before they could start any trouble, I will stay diligent and keep them sprayed as I see them.
