A man killed his wife because she refused let him into the bedroom of their Brooklyn home, police said.

Loiseau Desmoulins, 56, allegedly choked his 63-year-old wife to death when she attacked him when he tried to enter the bedroom of their Avenue J home in Flatlands around 11 a.m. Tuesday.

The couple had recently been experiencing money woes, according to police sources, who added that Desmoulins told authorities that he was routinely booted from the bedroom.

The latest fracas erupted when Desmoulins tried to retrieve some of his belongings from the off-limits room, police said.

The two began squabbling, and Desmoulins grabbed his wife by the neck after she bit him on the hand, he told cops.

When stopped breathing, Desmoulins called 911, and was taken into custody.

He has been charged with murder, officials said early Wednesday.
