Answer: It sounds like your bulbs have fungus gnats. They lay eggs in the soil and the eggs hatch into small worms that feed on organic matter in the soil. In small numbers, the insect is merely a nuisance. To control them and the adult flies, lay a 1-2 inch layer of sand over the potting soil and spray the plant regularly with insecticidal soap. For a stronger control, try the product Knock-Out Gnats (available from Gardens Alive, ph# 812-537-8650, 5100 Schenley Pl., Lawrenceburg, IN 47025); this product contains a strain of Bt, a biological control, that controls the larvae. You can also repot with fresh potting soil to lessen the infestation.<br>The smaller bulbs may be a result of over watering. Try letting the bulbs dry out more between waterings and apply a time release fertilizer to the pots such as Osmocote.
