Take a few small wide mouth jars, put about 1" of apple cider vinegar and a couple drops of dish soap in it. Set these all around your house and in the area you have all your starts. Wait a couple days and see just how many of those things you catch in there. Dump when it gets full and start over again. Once you get them under control you might not be kicked out anymore.
P.S. I brought home gnats from the grocery store and they just kept multiplying. I couldn't figure out what to do and a friend told me what to do. It worked very well and within about 1 week all the gnats flying around me were gone. I haven't had any for a very long time.
