Re: little white critters in stool ... larvea? worms?

Hello - sounds like pinworms to me. Here is some additional info:

PINWORMS – the #1 parasite in the North America and Europe. They cause an itchy anus, digestive problems, irritability and insomnia. They are the most readily seen of all of the species of parasites because they live in the colon and they come out at night to lay their eggs in the anus and on bedclothes. The adults are white and ½ inch long. The eggs can become airborne and are able to live without host for 2 days. They are also transmitted by the anus – hand – mouth route. School age children followed by preschoolers have the highest infestation rates. If one member of a family has pinworms, it is highly likely that all members are infected. Children in day care centers and institutional settings are also at high risk for infestation from other children. If a child scratches, then touches something, the microscopic eggs are easily left for another child to put into their mouth.

ALSO make sure you disinfect your home while you are parasite cleansing to prevent reinfestation from the airborne eggs. Good Luck!
