Are Collembola contagious?
Yes and no. They are contagious to all animals. My dog got them, along with my brother’s dog. It’s a different when it comes to people. I initially got them from an old house that I was leasing during my senior year of college with five other girls. I was the only one who was bothered by them, and the springtail source was closest to my room. I took them home with me and unknowingly spread them to my house, dog, and mother, and later, my brother and his fiancee. And, then my mother to her boyfriend My brother’s other roomate initially got a rash and then did not notice them. My brother’s roomate’s reaction was similar to that of my boyriend. He got a rash, but then had no problems. So, it depends on the person. I can only guess at factors that makes a person susceptible; sensitive skin, thyroid issues, and allergies are some factors that those of us bothered have.
