BAT in my house!!

There is something unusual that has been going on in my house at night> The BATman Begins. It terrified me, and everyone else like Cheng Khang, Kenneth, Tuan Khoon, Brandon, Peik Hong, BUT not Mary Anne. It has been flying around my house almost every night when i first arrived here in Iowa. There must be a loop hole somewhere in my house (which i found it few days ago). It was actually the window's problem, it was not properly shut. Kenneth did experiment on the BAT by using Onions. It seemed that the bat does not give a "dam" on Kenneth's onions. Check it out in the video below.

Few nights later, there was another bat in my house. It was really scary, I cant describe well here, check it out in the video below.

Fortunately, the problem has been solved. Phew...
