Gilgo Beach serial killer suspect Rex Heuermann’s house was torn apart by investigators — and neighbors want it torn down completely.

Heuermann’s wife, speaking Wednesday after his Suffolk County Court appearance one day earlier, told the Daily News her future still remains uncertain after his arrest for the murders of three Long Island sex workers.

“The people in this neighborhood, they want this house gone,” said Asa Ellerup, who raised two children inside the home with the accused killer. “They want it bulldozed, you understand? They want it gone.”

Ellerup, standing in the driveway of the Massapequa Park residence, said the house was left in a shambles after investigators spent 12 days scouring the home for any evidence in the killings dating back to 2009 and 2010.

“We’re still finding other things that they destroyed,” she said. Prosecutors revealed at a Tuesday court hearing that investigators recovered thousands of pages of documents, along with other records and photographs, during their search of the residence.

Heuermann, 59, stood silently during the proceeding where he appeared in handcuffs and ankle bracelets. He has already entered a plea of innocent on the multiple murder charges.

His wife, who filed for divorce after the accused killer’s July 13 arrest near his Manhattan real estate office, complained specifically about the condition of her bathtub after the search was done.

“I can sit in it and I got a handheld [shower head],” she said. “But I really want a nice bath. Just to be able to get my hair all wet. Nice shampoo. Nice conditioner. You know what? One day, one day.”

A police car remained parked directly across the street to deter gawkers from stopping outside or snapping photos of the house.

Ellerup expressed appreciation to a neighbor who sent the family a pizza last Friday night and stopped in the driveway Wednesday to chat with her. But she said life remained a struggle since her spouse’s arrest.

“I can’t think,” she explained. “You ask me what do I want? … I want to be able to sleep for a couple of hours. I’m not sleeping.”
