Hey Everyone, this is the answer I received from another group regarding the mites and I thought I would share it with you….. Every worm bin will have a few mites, but when you start to really notice them than chances are your pH is dropping and your worm bin is becoming acidic. The lowering of the pH is caused by decomposing food, mostly from feeding too much for the amount of worms and microbe population that you have. Mite eggs come in on fruit and veggie skins. The mite eggs need moisture, and acidity to hatch, and the female lays eggs when this is the case. S,o let's change that, Take your lid and any coverings off your worm bin for 24-48 hrs. to allow the surface to dry out a bit. The worms will be fine they will burrow down. Mites are surface dwellers they do not burrow down into the vermicompost. They are attracted to low pH (acidity), excess moisture and exposed food. If you have any food on the surface turn it under. ( In the future dig a little hole, lay down some dry carbon that is approx the same volume as your food, sprinkle with grit and cover with existing bedding.) After 48 hrs fluff the worm bin good, and add 1-2 handfuls of dry carbon into the mix. Sprinkle a 1/4 cup of a pH buffer across the surface (I will explain pH buffer below) Don't feed again until all the food is gone. While your bin is surface drying, use a damp paper towel and remove any mites on the sides or lids and dispose of the paper towel after. If your worm bin is quite wet when you are fluffing it, take a few larger pieces of dry cardboard and slide them down between the inside wall of your worm bin and the vermicompost. This adds more carbon to the system and helps to dry it out a bit. Use a type of grit that also doubles as a pH buffer like pulverized eggshells, or any powdered version of the following: agricultural or garden lime, dolomite lime, calcium carbonate, oyster shell or glacier rock dust (NOTE: DO NOT USE Hydrated lime as it is caustic.) The nice thing is that all of these calcium based pH buffers help to adjust acidic conditions plus they are also an awesome grit and a calcium supplement for the worms. I use one of the pH buffers I mentioned above as grit at each feeding, plus at the first sign of white mites or pot worms I sprinkle the pH buffer across the surface, then fluff, and add another sprinkle on the top surface after fluffing. If you put a small piece of damp cardboard (approx 4 inches by 3 inches) on the surface after you have down everything above, then check that piece of carboard everyday, and if there are 2 or more mites on it, dispose of it and replace it. It may take a few days but this will really kill off the mites, and with less mites, there is less eggs.
