Springtails are most commonly outside in damp areas: under loose soil, debris, mulch, and potted Plants. Outside they feed on fungi, algae, and rotten vegetables. They may also be found inside homes in damp areas such as: near drains, insulation, moist basements, and window moldings. They feed on cork, insulation, and indoor potted plant matter; to name a few. Springtails are very small to the eye, growing less than 1/12 inches long, and appear to be white or grey. They do not fly; instead, most springtails have two long fork-like appendages which cause springtails to jump when moved suddenly. They are generally non damaging insects, however, are considered pests because they appear in large numbers.
