About moths & butterflies
The monarch butterfly is one of the moths & butterflies. Moths and butterflies have wings covered in tiny scales and go through complete metamorphosis. The caterpillar stage does all the feeding and damage, while adults sip nectar or, in some species, don't eat at all.
In pantries and closets, the moths you see flying are a signal. The real problem is the larvae feeding in food or fabric nearby.
Should you get rid of it?
No control is needed. Monarch Butterflies are not pests, and many help by eating other insects or pollinating plants. If one is indoors, move it outside with a cup and a sheet of paper.
