Here’s the dirty little secret: the itch can last two to four weeks after the little bastards are dead. Why? Because your immune system is slow to forgive. It’s like when you break up with someone and still feel angry for a month—except the anger is histamines and your ex is a microscopic, eight-legged jerk.
So, stop scratching every time you feel a tingle. If you’re still clawing at your armpits a week after treatment, you might be fine. But if you see new burrows—those tiny, gray, wavy lines that look like someone doodled on your skin with a Bic pen—then Houston, we have a problem.
