I know it sounds silly, but when the bulbs are dormant (no leaves) place a
few banana skins on top of the pot, or if outside, around them.

Bananas release ethylene as they ripen and this can have the same effect as
smoke and burning in the wild. You can also try apples, as when they ripen
they give off more ethylene than bananas.
