WYANDOTTE, Mich. (AP) — Trick-or-treating is off-limits in a suburban Detroit neighborhood: There’s nothing sweet about bringing home a cockroach.

Officials in Wyandotte said a cockroach infestation has been confirmed at a vacant home after a tip from a trash hauler. The pests have been moving to other homes.

Sidewalks will be closed Monday night on a portion of 20th Street. City engineer Greg Mayhew said a Halloween ban will prevent “further roach migration.” Officials don’t want the bugs hitching a ride on costumes, the Detroit Free Press reported.

The city is trying to exterminate the roaches but “it will take some time,” Mayhew said.

According to Pest World, cockroaches can live without food for one month. As the pest start to make themselves at home, they are commonly found in humid or high-moisture areas.

“Cockroaches are some of the most adaptable creatures on earth, which makes controlling and eliminating a cockroach ingestion all the most difficult,” the website said.

Walking the street could help kill the cockroaches, but their eggs still could spread and survive, City Council member Todd Hanna said.
