The larva in humans arises when the blowfly larva enters underneath the skin through wounds or scratches, causing the appearance of a skin wound that may itch, pain or cause swelling and redness in the skin.Generally, the larvae hatch inside the skin of individuals because the blowfly lays its eggs on existing sores on the skin and after some time, the larvae hatch and begin to develop, feeding on the "meat" of the individual .The human botfly is curable and treatment should be guided by a general practitioner to remove the larva inside the skin. If the larva in humans is not properly treated, can lead to worsening of symptoms since the larvae can survive more than 1 month in the patient's skin.more video: https://www.facebook.com/FanpageApoioPolicial
