Could you work a systemic into the soil around them so they would absorb it? I do not use poisons on anything else but since these are not edible to humans and to protect my major investment in these I did use a rose and flower systemic when I planted them outside. I have seen no insect damage at all but I do have them in a cinderblock bed 16" off the ground. I think that is what I would do and it would give them time to be cleaned up well before you bring them in.

Yes... just water in a systemic... I use Bayer for roses and ornamentals. It's granular, so I follow the directions, sprinkling the proper amount, then I water it in well. I'm sure there are other systemics on the market, as well.

If you're really paranoid, you could re-pot your bulbs. I recently re-potted and separated my Sprekelia. I just carefully hosed off all the soil and worked the roots apart. Then, I just re-potted.

I admit that I only have 2 pots of bulbs outdoors... the Sprekelia and some Lycoris radiata, but they both will have to come in soon. I don't want any bugs coming in with them!

Good Luck!

Personally, I'd repot.
