Blood Suckers

First glance at the words "Blood Sucker", many will start to think of vampires or mosquitoes. BUT, I am not going to talk about either of them. The two extreme creatures that I am going to talk about, not only do they have disgusting appearances but are also blood-thirsty creatures.

They are the Fleas, and the Ticks.

Some facts about Fleas

• Flea larva may live on the carpets, or any fabric surfaces.
• The flea larva actually feeds on the poop of an adult flea besides dead skin debris of animals.
Eventually, it will spin itself into a cocoon, and can stay inside for more than a year waiting for a host to arrive.
• Flea can jump 150 times its body length, which is about 240m high for a human being of 1.6m! In order to attach itself onto its host.
• The flea has a very poor eyesight, it can only sense its hosts through movement and concentration of carbon dioxide.

• It can drink blood of up to 15 times its body weight. In conversion, it is approximately 750kg of liquid consumed by a person with 50kg body weight!
  
• The poops it produces are rich in nutrients for larvae to grow.
• One of the best way to get rid of fleas, is the use of vacuum cleaner.

Some facts about Ticks

• A tick is an eight-legged bug, a relative to spiders.
• Very similar to fleas, a tick tracks its host by following the trail of carbon dioxide released by the hosts.
• A tick locates the blood vessels closest to the skin surface of its host, at which it will bite and start leeching for blood.
• The horrifying fact is that, a tick can drink up to a maximum of 600 times of its body weight of blood! (which is 30,000kg of fluid for a 50kg-person)

• Once latched on a host, a tick may be 'glued' onto the host and suck blood for up to a few days. Until its body weight increases about several hundreds times its original weight!
