Difference Between Ticks And Fleas (With Table)

Ticks and Fleas are common bugs that can transmit diseases to animals. They have some similarities like they are external parasites. That means that these insects live on other animals to feed themselves. These animals that they feed on are called hosts. But they are much more different from each other in appearances, lifestyles, habits, and in their treatments as well.

Ticks vs Fleas

The main difference between the Ticks and Fleas is that the tick has a 6-8 leg arachnid, a joint-legged invertebrate animal. And they cannot fly or jump. On the other hand, Fleas have 6 legs, they are wingless but they can jump. Indeed, they belong to the Siphonaptera order of taxonomic rank which is used to classify the organisms.

Ticks are external parasites that belong to two major families: Ixodidae (Hard ticks) and Argasidae (Soft ticks). Ticks are found all around the world but they are mostly found in warm and humid climatic areas. Adult ticks have pear-shaped bodies and are 3 to 5 mm in length. They have four stages in their lifecycle.

Fleas are external parasites that are usually brown. Mostly the adult fleas are 3 mm in length. And their bodies are flattened sideways to let them move through their prey or host’s feathers. Fleas don’t have wings but they have the ability to jump. They also have four stages in their lifecycle.

What are Ticks?

Ticks are external parasites who feed off other animals like cats, dogs, etc. They are 6-8 legged Arachnids, which means they are related to spiders. Ticks have pear-shaped bodies. The adult fleas are up to 3 to 5 millimeters in length. They have sharp mouthparts through which they cut through the skin and bite to access blood. They leave irritated red skin behind, which can burn a little too.

Ticks cannot fly or jump. They wait in the position called questing to climb on their host. In questing, the ticks hold their first pair of legs outstretched. And use their third and fourth pair of legs to hold onto the grass use them to climb to their host by pushing themselves forward. Ticks feed on multiple hosts in their lifespan.

Their lifecycle has four stages: egg – six-legged larva – eight-legged nymph – adult. And leaving the eggs of ticks, ticks feed on hosts in all three stages of their life. Indeed, ticks are very patient predators, they can wait for the right prey for an extended period of time. Ticks can live up to a few weeks to three years.

Also, ticks can lay thousands of eggs at a time, however, they don’t live much after that. They also transmit deadly diseases like Lyme diseases, Rocky Mountain spotted fever, etc.

What Are Fleas?

Fleas are external parasites as well. They belong to the Siphonaptera order of taxonomic rank. They are brown in color mostly and are 3 mm long at the most. Fleas are wingless creatures, they cannot fly but they can jump really far. Fleas can live up to 3 to 4 months.

Fleas live only on one host during their lifespan, mostly. They can go from one to another host but that is very rare. They don’t feed off multiple hosts.

Their lifecycles have four stages: egg – larva – pupa – adult. Only adult fleas feed off the hosts. They don’t feed on hosts in the rest stages of their lifecycle. Fleas start laying eggs just after they start feeding. And they can lay up to 20 to 40 eggs per day for weeks as long as they are feeding and alive. They lay egg wherever the host goes, that means fleas will not leave the host that easily.

Fleas prefer to live in warm temperatures are. Indeed, if they jump on you they will try to bite you at warm places of your body like armpits, or groin. Fleas transmit diseases like tapeworm, flea allergy dermatitis, and bartonellosis, etc.

Main Differences Between Ticks And Fleas

  1. Ticks are parasites who feed on different or multiple hosts in their lifespan while Fleas feed on only one host throughout their lifespan.
  2. Ticks can live from few weeks to 3 years while Fleas can live up to 100 days only that is 3 and half months.
  3. Ticks can lay thousands of eggs at a time, but they dont live much longer after laying a huge number of eggs. On the other hand, Fleas can lay 20 to 40 eggs per day for several eggs as long as they are feeding off the host.
  4. Ticks can survive in the near-freezing temperature however fleas cannot survive that low temperature. Although, both ticks and fleas prefer warm temperatures.
  5. Ticks can spread deadly diseases than Fleas. Indeed, Ticks are hard to kill than fleas.
  6. Ticks cannot fly or jump but fleas can jump.

Conclusion

Ticks and fleas are external parasites, they feed off other animals. And both have their lifecycle in four stages. That’s the few similarities both have but they both are different organisms and belong to different classes and order in the organism nomenclature.

Ticks are deadly parasites. They can live on many hosts in their span of life. Ticks belong to the arachnids class that means they are related to spiders. They can live up to three years. And they can transmit deadly diseases like Lyme diseases etc.

Fleas are wingless but they can jump. They live on only one host during their life. They are parasites and they can be dangerous too but they are not as deadly as ticks. However, they can transmit some serious diseases like tapeworm and bartonellosis.
