Mayor Eric Adams has another pest in his life!

Hizzoner bashed Curtis Sliwa as an unemployed nuisance Wednesday after his former mayoral rival offered to become New York’s “rat czar” and to personally step in to put an end to an ongoing rodent infestation at Adams’ Brooklyn building.

“I will take him up on his offer. You know, if he says he will be my rat czar for free, I’m going to call him and I would like for him to come on board to do it,” Adams told reporters at a press conference Wednesday.  

“Don’t put it out there if you’re not willing to live up to it.”

Sliwa on Wednesday had floated his plan to release feral cats at Adams’ multi-unit Brownstone and to “help” the rodent problem by serving as the city’s rat czar “at no cost” after the mayor’s property was hit with two tickets for vermin.

Asked about the offer at a press conference, Adams fired back with a snarky tone by calling Sliwa’s bluff — saying he that he’d hire him to work for free since the Guardian Angels founder is “probably looking for a job” after losing to Adams in last year’s mayoral race.

“Tell Curtis: come to be my rat czar. Okay, and he’s going to realize this is not a Tom and Jerry playful commercial here. This is real stuff,” Adams added.

“I will make sure we bring him on board, he can be part of our internship program because I know he’s probably looking for a job since he lost a job that he was trying to get,” he said, referencing the mayoral race.

Adams was hit with two new Health Department summonses for vermin on his Bedford-Stuyvesant apartment building after finding evidence of a rat “runway” and other telltale signs of rodents at the multi-unit brownstone, according to records reported by The Post Tuesday.

The tickets came seven months after a previous Health Department inspection found evidence of a rat infestation at the building.

On Wednesday morning, Sliwa put out a press release noting, “Adams… has been hit with a new round of tickets for having rats at his building in Brooklyn.”

“He is frustrated because he has tried everything to remedy the situation. Everything except Feral Cats,” he proclaimed.

“During the Mayoral campaign, everyone became familiar with the fact that Adam’s opponent Curtis SLIWA and his wife rescue cats from the animal shelters before they are euthanized and manage Feral Cat colonies in Brooklyn,” the press release added. 

“The SLIWAS will go to Eric Adam’s building on Wednesday, Jan 4, at 2:30 PM and offer to organize a Feral Cat colony for Adam’s building and his neighbors on the block.”
