If you’ve never heard of Collembola, you’re not alone. Until recent years, it was thought that these soil borne creatures were essentially harmless. Even doctors vehemently denied that springtails were likely to infest human hair and skin. Folks who suffered from chronic itching, biting and crawling sensations were often considered delusional, but that mindset is slowly changing. Mounting evidence suggests that these micro-tiny pests can be surprisingly invasive.
Thanks to the tenacity of folks like Dr. Frans Janssens and his colleague, Dr. Kenneth A. Christiansen, the scientific community is beginning to recognize that springtails can pose a very real threat to human comfort when present in large numbers. The two researchers collected scores of reports from homeowners, doctors, and pest control operators in several countries, including many regions of The United States. Within the gray areas between casual testimony, scientific observation and concrete medical documentation, a startling picture emerged. Collembola are everywhere, and it’s not impossible for them to latch onto humans and animals.
As inhabitants of fertile soil, springtails are likely to be found just about anywhere. The more you water the lawn and apply fertilizer, the happier they’ll be. They are considered the most abundant arthropods on earth. Since prehistoric times, they have survived frigid winters and very hot summers, but their numbers decrease exponentially under dry conditions.
