Lice are not the same type of problem. They do not survive off a host. But no....Do not try to use a prep set up for animals on yourself. These things are toxic.
Something very aromatic, like cheap aftershave has a repellent quality that helps a lot. Rubbing alcohol watered down a little can work, but I always used Brut, or Hai Karate( dollar store items today).
Another issue is hyper allergenics. Some people will display what looks like ten bites for any one genuine bite....they will all itch and scab too. A doctor can give you more info.
One last Thing....are you sure its fleas, and not bedbugs?
One last Thing....are you sure its fleas, and not bedbugs? If the bites are random, fleas may be the issue, but if they are
( a: not in your hair
(b: in places like the backs of your hands on arms and around your neck
(c: any place that WONT be under your covers at the time youre deeply asleep
Theres a good possibility they're from bedbugs. Even seeing a fkea doesnt rule that out. If its that persistent a problem...call a pro.
