Yup, as Lucy says, if they are still in the leaves, you can squash them, or if you're not sure about that, you can fill a water pistol with a BT and water mix, and squirt it down ,inside the leaf folds. Although, BT DOES affect honeybee larva, as well. But , any "chemical" control, or any of several "natural " controls (like BT) will affect SOME aspect of the honey bees life cycle. Thing is, if there are no blooms to attract them, the bees won't be there, anyway.
