Difference Between Flea Bites and Bed Bug Bites
The bites have been discussed in great detail, and the key points to remember before taking action to get rid of these pests are:
- Flea bites are at random.
- Bed bug bites will often be 3 or 4 in a row or straight line.
- Bed bug bites take a few days to appear.
- Flea bites appear within an hour and itch immediately; bed bug bites start to itch progressively.
- Bed bug bites are raised and flat.
- Flea bites are raised and swell quickly.
Another difference between these bites doesn’t have anything to do with appearance. Bed bugs are pests, and they’ll feed on you for hours if you allow them. But these bugs pose little risk to human health because they have not been shown to be able to transmit diseases to humans.
Fleas, on the other hand, have been shown to be able to transmit:
- Cat-scratch fever
- The plague
Most flea bites are simply uncomfortable and won’t pose a risk to a human. But there is a small chance that a disease will be transmitted. If you get bit by a flea and start coming down with sickness or fever, a trip to your physician is recommended. Since the plague and many of the diseases that fleas transmit are not as prevalent as they were in the past, you’re likely at a lower risk of contracting these diseases.
When bed bugs bite a human, the delay in the appearance of the bite is due to it causing an allergic reaction in the body. Humans are allergic to the bug’s saliva, and it takes a while for the anesthesia and anticoagulants to react.
