Howdy dude,
I'm just doing a bit of research into this myself.
A friend told me that these little critters only affect indoor grows and a good way to deal with them is to sit them in the sun, outdoors and let the pots dry out most of the way. This will kill the adults and larvae.
If you try to tackle this indoors your best bet it to get some clean, freshly washed sand and make a half inch layer across the tops of your pots, as the young live in the top soil. If you have the sand there it'll trap them underneath when they try to emerge as adults.
Best advice, get them in the sun and let them dry out, if not an option, do a bit of research into the sand method. Not much else will kill the
