What and why?

Springtails is the common name and they are a net positive to soil life. its said if you have them its a good sign of healthy soil. add em into your compost pile to help t break down. They eat decaying matter and then shit it out making frass or insect poop. it in turn feeds the plants. If their population becomes to much and you dislike them. they can be eliminated with nematodes or BTi. But again, they are a good addition. place the ones in the runoff in some house plants. or outdoor in the compost/garden. Good Luck!
