Human only infestn: U get pin worms by putting egg contaminated fingers in the mouth.The eggs travel through, hatch & begin to live in your large intestines.Living pw's crawl out your anus &lay eggs.You get an irritant rxn to the glue like stuff the eggs are laid in, it will itch a lot. Rx is so simple & free of side effects many just treat on suspicion. Not all anal itching is pw, it can be poor other issues.
