Howdy All! My name is Ed and I just joined the list. I have about 40 houseplants (maybe 50) split between home and office. I live in Boulder Colorado. My office ones have these little black flying things that I want to get rid of. I don't want to buy any of those plant poison sprays. Enough toxins in the air anyway!! Someone told me that I could soak a cigarret overnight and then spray the water on the plant. Will this work? Any other natural cures I can try? Thanks!
