How do insents fly?

First of all, it is insects not insents. Yes insects can fly. Maybe not all of them but many of them do have wings. Beetles, butterflies, flies. All of these are insects.

If you are wondering if incents can fly, they certainly cannot. Incents are used to make a room smell good.(The things that look like thin sticks that are infused with fragrance.) Those are burned so the fragrance is released slowly.
