Do sodomy, bestiality, and killing fleas invalidate Hajj?

If a pilgrim in the state of ihram commits sodomy during Hajj, his Hajj becomes invalid, and he is obligated to repeat it the following year and sacrifice a camel (badanah). Similarly, Hajj is invalidated by bestiality according to some scholars. There is no disagreement that Hajj is invalidated by sexual intercourse in the vagina. The majority of scholars hold that killing fleas during ihram is permissible and does not incur any penalty, because they are not considered game. However, the Malikis are of the view that killing them necessitates a fidyah (expiatory payment).
