Then the best thing is to run a sulfur burner. YOu can get them at a grow shop. its a little pot with a burner under it you hang from the ceiling and it releases the sulfur into the air. I would not recommend trying to make your own sulfur burner, because if you get the temperature too high, the sulfur will burn your plants (I've done it). The more pure sulfur is, the better. A small quart of it costs only about $10. The burner itself is perhaps $80, can't remember, its been a few years ago since I bought mine.

If you can keep the relative humidity down, you will have less problems. I haven't seen any in my room for 2-3 years.
