At the University of Miami's Wound Cure Center, doctors are using maggots for wound healing now that the FDA has actually approved the medical use of maggots if they're grown in a sterile lab.
"One of the reasons why maggots are becoming more popular is the emergence of resistant bacteria. They eat away the dead or necrotic tissue, in the process they also eat the bacteria that's present, whether its resistant antibiotics or not, and they're painless," says Dr. Robert Kirsner, a dermatologist.
"It's like tickles, its nothing. They work and you feel like they move," says Maria Perez, using maggots for wound healing.
After a few days, maggot larva needs to be removed before they turn into flies and some patients need more than one treatment.
