Since the tapeworm thrive in the stomach, they eat and breed there. Their eggs does not digest, and is found in feces. tapeworms in feces can also produce eggs for quite some time. If animals sniff feces (as they often do), they might get infected by actually managing to sniff up particles contain…ing eggs.. Some even have a snack on feces. If live tapeworms in that snack, then they very quickly have the infection themselves. The eggs are supposedly in need of an insect host to develeop, but what attracts insects if not feces... I myself disagree with the actual need of an insect as a host for the egg, because a tapeworm infection rapidly grows. They thrive in the stomach. To eliminate the scolex/tapeworm and its eggs in the feces reduses the possibility of reinfection and spreading of the parasite. I am sure there won't be any calls from any preservation groups if tapeworms were to become extinct :-) To get rid of feces and its possible eggs and scolexes: Heat is very effective. Simply put it all in the fire. or at least wrap it up in those disposable plasticbags and put it in the dustbin. (MORE)

Scolex is comparatively much smaller in size than a proglottid, when held near each other, as scolexes have recieved much less growth hormone in their lifetime, making them much smaller in size.
