HAMMERHEAD WORMS are the new invasive species to watch for in your garden. They are carnivorous, will decimate your earthworm population. They look very similar to regular earthworms except for the distinguishing shape of their heads.
ANOTHER DASTARDLY creature to be aware of is the Wasp. Not all wasps but many wasps. See our beekeeping page for lots of information on the destructiveness of Social wasps and the absolutely devastating effect they have on bee populations, both in-ground and in hives.
