What is those things that are tiny and black and jump around like flees?
Those little annoying creatures are called Springtails. This name comes from the fact that they have a spring like structure that allows them to jump. Springtails are found worldwide with over 675 spices found in North America. These insects inhabit only moist and damp areas because they loss water from their bodies rapidly through cuticles where they breath. Most species of Springtails live in the soil in great numbers-up to 50,000 per cubic foot. They enter the home looking for moisture if the moisture is low in the natural habitat. They can also be brought into the home in potted plants and are attracted to bright lights. Springtails feed on decaying vegetation, fungi, bacteria, pollen, algae, lichens, arthropod feces and carrion. Control: Dry out the area of infestation. The Springtails will either die or leave.
