Springtails are very small, only around an eighth of an inch in length. They can be a variety of colors but are most often dark in coloration, either brown, black or grey. Slender, their most defining characteristic is the one that gives them their name. Springtails are wingless, but as the name suggests they will use their tail like a springboard to jump several inches, an impressive feat for so small a creature. They are similar in size to fleas, but have more rounded bodies that are easily squashed.
Like woodlice, springtails feed predominantly on decaying organic matter. However, they have also been known to feed on fungi and algae as well. Due to these dietary habits, springtails are most often found in damp areas. Mulch is one of their preferred hiding places. This can lead to problems, especially during dry months, when springtails can enter your home looking for moisture. Some of the most likely areas for springtails indoors are around potted plants, or in kitchens, bathrooms, and damp basements.
