Is there anything duct tape can't fix?
Some studies suggest that using duct tape to remove warts is more effective than freezing them -- although that theory is still up for debate. It's not simply the pulling of the adhesive from the skin that removes warts. It's actually the covering of the warts that treats them.
Researchers believe that using duct tape to cover a wart stimulates an immune response from the body that speeds up healing. Of course, this process doesn't occur immediately. In fact, it can take weeks for the duct tape method to work. And the bad news is that the duct tape needs to stay on the entire time. So if it's appearance you're worried about, this may not be a much better option than waiting the virus out.
The next method of flat wart treatment is more common.
