How Long Do Flea Bites Last?
Although fleas prefer getting their blood meal from non-human hosts such as dogs and cats, we are still not an exception. Believe it or not, fleas sometimes go for human blood.
Duration of the flea bites directly depend on the person being bitten. In most cases, flea bites last only within 24 to 48 hours. In fact, most people don’t know that they just got bitten by fleas.
But not all of us are lucky enough to overcome flea bites pretty well. There are those who are pretty much sensitive to flea saliva which is considered as the main culprit to flea bite itching.
People who are very sensitive to flea saliva experience intense itching from flea bites. This rash develops into swollen welts that can last from one to two weeks.
In worse cases, flea bites can cause allergic reactions and secondary infections. If you feel nauseated with swelling on your face, feel extreme pain around the bite mark, and have difficulty in breathing, it is strongly recommended to seek immediate medical attention.
What Do Flea Bites Look Like?
Prior to securing their blood meal from a human host, fleas inject their saliva to prevent blood from clotting and to numb the bite area so that their presence won’t be detected.
When this happens, the human body’s natural reaction would be to release histamines as a natural defense mechanism. This chemical reaction with the flea saliva causes rash and itching.
Flea bites look like tiny red bumps that appear in clusters or in patterns. These bites look more like that of a mosquito only smaller. Flea bites are usually closer with each other with a halo-like shape surrounding the bite mark.
In cases where flea saliva triggers allergic reactions, bite marks develop into large welts. Continuous scratching due to extreme itchiness can lead to secondary infections wherein welts develop into blisters.
