This New York suburb is getting crappier by the day.

Orchard Park residents have a “Mad Pooper” on their hands. One woman has called cops about a delinquent defecator stinking up her lawn, and someone placed an ad warning the foul feces fiend to quit it, the Buffalo News reported.

“To the person/jogger who is pooping on our lawns in the Village of O.P.: STOP!!” the anonymous ad in the Orchard Park PennySaver reads.

Multiple homeowners have been victims and are determined to catch the pooper in the act.

“We have installed trail cams to identify you!” the ad reads.

Orchard Park police also received a complaint last month from a woman who said she found feces — and tissue paper — more than once outside her home. She thinks the stinker may be a jogger, cops said.

Police have had to deal with “Mad Pooper” calls before — though they usually involve Buffalo Bills games at New Era Field, they said.

If the culprit is caught, they could face possible public lewdness or exposure charges.

In September, Colorado’s Mad Pooper became an international sensation when mom Cathy Budde and her kids caught a still-unidentified jogger mid-squat on their lawn.
