Hi! We have a swampy yard that we are trying to remedy (in south eastern West Virginia) and have put in a drainage system of pipes and gravel throughout the entire back yard. Now, in the winter/spring, we are INFESTED with these spiders (attached). They are really small and with every step you take in the grass, about 50-100 move with you. What are they and how do we get them to leave????
You have baby Wolf Spiders. They are hunting spiders and do not build webs. The young are sometimes extremely plentiful in the spring as you well know. Soon natural selection and survival of the fittest will occur and they will feed on one another. The population will then be in check.
