Parasite bite is harmful to live beings. So, it is necessary to remedy if we have been bitten. But the treatments differ from bug to bug. As a result, it is mandatory to identify the bug bite type. People often get confused between flea bites and bed bug bites. In this article, we are presenting Flea Bites Vs Bed Bug Bites. so that people can easily distinguish between these two bugs after reading this article.

Flea Bites vs. Bed bug Bites: Introducing the Parasite:

If we want to know about Flea Bites Vs Bed Bug Bites, we need to know about the parasite that causes them. Fleas cause a flea bite, and a bedbug causes a bedbug bite.

What is Flea?

Fleas are a mainly wingless parasite that is oval-shaped and around 2 to 8 mm long. It is light to deep brown, has a disproportional small head and six legs. Fleas are blood-sucking insects. It has large hind legs, which enable them to jump up to 18 cm. Three main species of flea infest living beings are-

  • Cat Flea (Ctenocephalides felis)
  • Dog Flea (Ctenocephalides canis)
  • Human Flea (Pulex irritans)

What is Bedbug?

Bedbugs are small, oval-shaped, and brown colour parasite. It lives on the blood of humans or animals. It cannot fly but can move smoothly over floors, walls, and ceilings.  Female bedbugs produce hundreds of eggs over a lifetime about the size of a speck of dust.

Flea Bites vs. Bed bug Bites: Feeding Procedure:

The feeding procedures of Flea Bites Vs Bed Bug Bites are unique. At this point, we will focus on their feeding procedures to know the insects in detail.

Blood Feeding by Fleas: Fleas are a blood-sucking insect that survives on animals and humans’ blood. According to a survey, adult fleas can survive for some months without blood. They use their saw-like mandibles to cut through the skin. Flea saliva contains anticoagulants that ensure the continuous flowing of blood. Female fleas are stimulated to lay their eggs after feeding. The eggs are light-coloured and oval-shaped.

Blood Feeding by Bedbugs: Bedbugs (Cimex lectularius and Cimex hemipterus) are nocturnal feeding insects. Bedbugs usually feed at night. While feeding, they inject a salivary secretion into the wound to prevent coagulation. Bedbugs use a small tube-like structure named proboscis to pierce the skin.

Comparison Based On Attacking Place:

Every parasite has a comfortable biting place. So it is helpful to identify the parasite based on their attacking zone.

Attacking Place for Fleas: We usually find the bite marks caused by a flea in our lower body part. Flea bites are most commonly found around –

  • Waist
  • Ankles
  • Legs
  • Armpits
  • Groin
  • Folds of the knee

Flea bites usually look like small, red bumps in clusters of three or four or a straight line.

Attacking Place for Bedbug: Bedbugs tend to bite on the upper half of the body. This attacking place mainly include-

  • Face
  • Neck
  • Arms
  • Hands

Bedbug bites are generally small and have a dark red spot in the middle of a raised skin area.

Comparison Based On Carrying Diseases:

It is known that parasites often act as a carrier of diseases. As a result, parasites are considered harmful to living beings.

Diseases Carried By Flea Bites: Fleas carry some human diseases. The most famous disease carried by fleas is the plague, which created the whole world’s pandemic situation. Fleas are known to televise tapeworm larvae and the disease named murine typhus. They are also most notorious for transmitting bubonic plague from wild rodents to humans in certain parts of the world. Fleas are harmful to animals too. They even bite cats and dogs. Mycoplasma haemofelis is transmitted to cats through flea bites. Cat scratch disease, which is mainly caused by Bartonella henselae, is also shared by fleas.

Diseases Carried By Bedbug Bites: Bedbugs are not known to spread disease.  Bed bugs can transmit Trypanosoma cruzi that causes Chagas disease.

 Juxtaposition Based On Effect On Children:

The children’s physique is different from the adult, and the children’s immunity is also low. So parents always feel worried about the children.

Flea Bites On Children: Flea bites are not considered that dangerous in children. The bite mark looks like a little red bump on the infant’s skin. But like adults, scratching is harmful to the children also in this case. So, I suggest to cut off the nails of the children to prevent scratching.

Bedbug Bites On Children: In some cases, children do not react towards bedbug bites like a mosquito bite. Like flea bites, bedbug bites are also less harmful for children. But it is recommended to keep an eye on the children whether they are scratching or not as scratching cause skin infection, such as impetigo and cellulitis.

Flea Bites vs. Bed Bug Bites: Finding Place:

Not all parasite uses the same spot as an habitant. Different parasites prefer different places.

Habitants Of Fleas: According to Wikipedia, the fleas population consists of roughly 50% eggs, 35% larvae, 10% pupae, and 5% adults. The adult fleas, which are mainly bloodsucker, live on animals and human beings. The remaining population inhabits near surrounding areas and environments of the potential host species. These areas are usually warm, shady, and humid and therefore usually indoors in regions with a cooler climate.
