Question
Hi Jack,
I'm hoping you will be able to help me.  
Today, I inherited a potted plant from a neighbor whose roommate had left it behind after a move.  It had been left outdoors for some time.  It looks relatively healthy, if not a bit neglected.  The soil was overly moist, so I decided to repot it, and while I was doing so, noticed that it hosted an impressive number of slobbery looking creatures: many slugs or slug looking things, and a few small millipedes.  I washed the roots of the plant carefully with sink water and have repotted them in fresh soil in a fresh pot, but I'm wondering: have I really gotten rid of the pests?  Could they be burrowing in the roots?  The plant is a thin tropical plant, that looks like a very spindly Japanese Maple.  
Thank you for your expertise!  As a novice container gardener, I really appreciate it!!!  :-)

Answer
Mari,

I'm not sure exactly what you found but I doubt they were pests at all. I suspect these were just critters that crawled into the pot when it was outside. Re-potting was exactly the right thing to do in this case. If you see them again take a picture and I'll be able to give you a better idea about what they are.
