Bite of bed bugs and fleas

There is a noticeable difference in the bite of these bugs. Bed bugs tend to bite on the upper body, whereas fleas tend to bite on the lower body. Is it itchy immediately after the bite? It might be a flea. Some people don’t show an itching reaction to bed bug bites. No matter which kind of bites you encounter, you should take them seriously and look for other signs that an infestation may be present.

What are they feeding on? Adult fleas, like bed bugs, feed on blood to reproduce, but the larvae of fleas will feed on frass, or feces. Finally, the most common distinction is that fleas prefer animals, and bed bugs prefer humans. 

Either way, it is essential  to check if there is an infestation of these tiny disturbing creatures.

Appearance of bed bugs and fleas

What does the little crawling bug look like sideways? Fleas will look narrow, but bed bugs will appear wider and flatter. The average size for an adult flea is ⅛ inch long, but the average size for an adult bed bugs is a bit bigger at 3/16 inch long. 

What is the color? Both adult bugs are brown, but bed bugs will look reddish after drinking blood. 

These bugs mature in different processes, too. Fleas change from larvae to an adult by a complete metamorphosis: eggs, larvae, pupae, and finally adult. However, a bed bug will mature through a slower metamorphosis: eggs, nymphs in several stages, and finally adult. 

Here’s some appearance differences through their maturation stages:

  • Bed bug nymphs look smaller and and paler adult bed bugs
  • Cat flea larvae closely is easily detectable by looking like maggots
  • Cat fleas and bed bug eggs are white, but the fleas have a pearly shine


Most people wait until they see an infestation to act. Don’t let that be you! Start with prevention. If you manage or work for a business were people sleep (like a hotel or apartment building) you can imagine how an outbreak would cause an immense amount of stress. If you’re a pet owner, you would never want your pet to have to suffer from fleas.

Staying in a hotel? It’s a good practice to check the headboard of the bed and the seam of the mattress in your hotel room for bed bugs. Bringing furniture into your house? Check around for bed bugs here too. 

Flea prevention starts with your veterinarian. Be sure your pet is getting its regular treatments.



If you notice you have a bed bug or flea issue, have it taken care of as soon as possible. 

Here are some signs of an infestation: 

  • Shed bed bug skins
  • Black fecal spots 
  • Adult bed bugs
  • Excessive scratching from your pet. 

Know where to look. Bed bugs can often be found near or on a bed, or anywhere seating area. Take a look around places your pet likes to spend time: this is normally where cat fleas can be found.
