I am one of those people who allergic to flea bite. I got severe pruritis (itchiness) that lasts for at least a week. The bites also left horrible reddish/blackish marks on my skin, causing me looking like I'm having a some kind of skin diseases or something.
Symptoms are itching on skin and around beard. What can we do? Dog and cat have been treated. Have an exterminator. But still having trouble getting rid of fleas.
