Flea bites vs bed bug bites

When it comes to comparing bed bug bites vs flea bites, most people find it a challenge. The reason is that the bite marks of these insects are not easy to tell apart. Bear in mind that most bites in your home from insects are either from bed bugs or fleas. These insects annoy anyone with their bites while fleas may act as disease carriers. This post compares these insect bites and gives you tips on how to deal with them.


  • Flea bites are found commonly on feet, legs, armpits and waist. They can also appear in areas that the insect had access to. Their bites are swollen, red, always itch and appear blotchy. They may occur with rashes in some cases. They appear in small clusters with a white shape around the bite mark. You can easily spot the white form when you press your finger or stretch your skin around the bite location.
  • On the other hand, bed bug bites are different from flea bites. They appear as small, hard and swollen lumps similar to mosquito bites. They often bite on your neck, arms and hands. They itch; just as flea bites but don’t have the rash response that flea bites trigger.
  • Bed bugs feed in a line, which means their bites have a linear pattern compared to the cluster of flea bites. They appear inflamed and can blister at times, but lack the white shape mark that flea bites have. Bed bugs feed less frequently as compared to fleas, which mean that you will spot their bites less regularly as compared to fleas that feed continuously. It means that flea marks are a recurrent feature if not dealt with.

How to Spot Fleas and Bed Bugs

  • Fleas are small creatures, for example, smaller that the tip of a pen, which makes them hard to spot. You should pay attention to the shape of their body and legs if you spot them. They have thin, brown and flat bodies with no wings and a hard shell.
  • Their hind legs are strong and large for jumping. Fleas prefer pets or animals to hide and feed on them. Signs that your pets or animals have flea is the loss of fur and appearances of patches. Another sign of them is flecks of what appear to be dirt.
  • These flecks are flea waste, and the red dot is red rings of the blood if you touch them with a wet cloth. Consider wearing white socks to know if brown fleas are jumping on you.
  • Bed bugs, on the other hand, are often found on your bed. Keep an open eye when cleaning or changing sheets. If you spot bloody or rusty stains, that could be one sign of them. Dark spots indicate either bed bug bleeding or bed bug waste. Bed bugs are also bigger that fleas.
  • Their body appearance is oval shape, flat with a reddish brown appearance, can’t jump or fly, which makes it easier to capture them for confirmation or testing.


One risk that you should be aware of flea bites is that combined with a cat; they can transmit a condition known as cat scratch fever, which if left untreated, results in a sore throat, headaches, loss of appetite and swollen lymph nodes. Make sure you seek medical advice if you note these symptoms.

What to Do

  • Consider a cold compress or special lotions to soothe the bites and itchiness of bug bites. If you had scratched and opened a blister, wash the area with soapy water and pat it dry to guard against infection.
  • Consider seeking the services of pest control experts. That’s because getting rid of their source can be challenging. Bed bugs don’t have central nets as fleas, which makes it difficult when tracking them down. Fleas also breed fast, making their eradication process difficult.

Final Thoughts

The above comparison post on flea and bed bug bites should make it easier for you to know if you need the services of a pest control expert. Bear in mind that fumigation is an option which depends on the severity of the infestation. Make sure you ask for written quotes and plan your routine for the best outcome.
