fleas

Are fleas sentient beings? Is it morally wrong to kill them if your animal has fleas? Should we just use repellents? What is your opinion; if an animal has fleas and is really suffering, should we kill the fleas? Is there another way to remove fleas without killing them?

Have you ever had fleas in your house? Feel free to share your experiences in this thread. Below is my own story. Back in 2012 I discovered mystery bites on my person, mostly around my ankles and legs. New bites seemed to appear every day or so, and yet I couldn't figure out where they were...

Apparently, it was air-borne. http://www.theguardian.com/science/2014/mar/29/black-death-not-spread-rat-fleas-london-plague
