Snakes, Spiders, & other "visitors"

Since moving to our new location we have seen quite a few snakes.  I ran over a puff adder yesterday (Sunday) on the way home from church.  Last week while I was in town Gwen found a small snake just inside our kitchen door.  She killed it!  The picture below, thankfully, wasn't taken in our house, but I'm sure they are around since we live in an old farm house.  We did catch a mouse in a trap, and we also found a mole under our stove.  I know you would be interested to know that for about two weeks we also found little white worms in our kitchen about every morning.  The mystery is that we also found them in a closed cupboard inside one specific stack of bowls.  They were never anywhere else in that cupboard.  We even moved the bowls to the other side of the shelf and we still found one in the top bowl the next morning.????
