If you've had problems with your worms or bins and have found the solutions, write them here to help others who may be experiencing similar difficuities.

1. My worm bin has a lot of white, fluffy mold growing in it.  Seems like too much. 

   Solution:  Not enough air is getting into/through the bin.  Find ways to let more air in.  You can get PVC pipe, drill some holes in the sides, and place it so that it extends from the bottom of the bin to the top, 

allowing more air into the soil.

The screen is a good idea on top. With a screen and enough carbon  on the top layer the fruit flies should disappear instantly.
 Roaches are part of the compost cycle. I see them all the time  in my pile.  I do know someone who was growing worms in his garage and lost them all to a "beetle infestation".
 I don't think those were roaches but some kind of beetle.  So keep an eye on them.
 You can pile up the pile as long as it doesn't get hot, usually 1-2 ft.
 Remember, you're balancing water, air, nitrogen and carbon.  Those are the elements to adjust to get the balance you want.  Moist is good. Wet is too much. Plenty of air is really good.  You might need more air.
 Great questions, thanks for asking
 Cristal          I was off island for a little over 2 months and had a friend feeding and watering my worms.   When I returned, the worm row and bin were super flat (the friend hadn't added any carbon material while I was gone).   I tried to dig deeper to see how everything was underneath and found a complete mass of avocado roots, which also were  very dry.  The avo roots completely took over the whole row/bin except the top 1/2 inch.  I'm assuming the dryness may  be due to the roots taking up all the moisture. So I'm not putting any more avo seeds in my worm bins.  Sue   (I don't know how to get this writing into the proper placing.)
