I read your online report on buffalo gnats…very interesting.  Would you be kind enough to tell me how I can kill them in the larvae or pupae stag?  They are in the basement (100% finished) of my home and I can kill the adult flies with a pesticide by Bayer, but the pupae are crawling all over the floors, walls, and ceilings of my finished rooms.  What can I do to kill them in this stage at the source before they start crawling all over my basement and become adult flies?
