I had an infestation pop up overnight. Made small traps with Apple Cider Vinegar and a drop of dishsoap, cover with saran wrap and poke holes with a needle, tack, etc.
I wiped out an entire infestation in less than a week.
I like the idea, here is a similar method that I've used before to kill flies, gnats, moths, anything that's flying around your soil.
What you do is get a tray or bowl of very light soapy water, place the bowl/bowls/trays? around or near on the floor (or in a safe apparatus possibly?) nearby the infestation, preferably below your plant containers and not in an area where they might accidentally tip over.
Then the second part is get a single regular clamp light ( or similar bulb setup, even a small table lamp with a reflector on top would work, I've used before actually) and get a normal maybe 13 watt cfl or similar led SIL bulb (some bulbs light emittion may attract bugs more than others) and attach the light downwards facing towards the floor, maybe 12"-18" inches off the ground and securely attach the clamp light to a sturdy safe base in the proximity of the plants. And simply arrange your bowl traps around your light source, the bugs come a flying.....
This method only works during lights On, as we all know extra light during the dark phase causes hermie issues. An alternate idea would be to place this setup outside of your grow area, or have 2 setups and just rotate during light & dark periods, just be sure no spillage of light occurs.
You could also use the apple cider vinegar as you have mentioned above, in the water, or place another attractant below the light in the bowls like fruit.... but be aware that fruit spoils quickly and germs from the gnats may spread to the plants, so change the fruit or whatever frequently to avoid this issue if you use this as part of your method, as an attractant.
Just make sure to take all the precautions necessary as to not spill your bowl of soapy water is one the only risky issue's with this method, and I mean unless you spill it directly onto your plants root ball I'd imagine you'll be fine, and hopefully you'll have under control before flower if possible (Definitely don't want soap water making it to your buds
).
As a lover of simplicity, this is one of my favorite methods to control such pests, I also like the fly tape traps also, just be aware that adding extra attractant odors around your home or building might bring more pests near you home or building waiting to work themselves in again, which may not be an issue if your room is sealed well, just thought I'd mention.
