Place plants under flourescent light.
Turn light on.

Go 24h- the chances of being able to mimic their previous lighting conditions are slim (early/late day shade plays into that).
Pesticides? Go to walmart. Get at least one bottle of GardenSafe fruit and vegetable insect spray. The active ingredient is pyrethrin- very safe. Quarantine your plants in a different spot than where thye will ultimately reside for a week whil you treat them for bugs. The bathroom, under flouros, is good for this.
