Beverly Hills has a bone to pick with Halloween.

The ritzy Los Angeles neighborhood on Tuesday outlawed Silly String, shaving cream and other similar items on the holiday, saying they cause to much of a mess.

The Beverly Hills City Council unanimously voted to ban young pranksters from using the sprays and hair removal products on public property or private property open to the public on Oct. 31.

The 24-hour ordinance aims to “create a safe family friendly environment,” the city said in a news release.

“When used improperly, the products outlined in the ordinance may cause harm to individuals, property and/or the environment.” The ban only applies to people under 21.

Extra Beverly Hills Police officers will be on the lookout this year for Silly String-wielding violators, who will be issued a citation after an initial warning, Sgt. Dale Drummond said during a City Council meeting earlier this month, the Los Angeles Times reported.

The cops were the first to propose the strict rule, arguing that their previous All Hallows’ Eves had been plagued by the mess.

Silly String, shaving cream and hair removal gels like Nair leave residues that require a significant amount of water to wash off damaged property, which then leaves tainted runoff that could pollute nearby waterways, officials argued.

They also pose health concerns if they make contact with a person’s eyes, while hair removal gel can be used maliciously on unsuspecting victims, according to Drummond.

Representatives for Beverly Hills — notably home to the rich and famous — did not immediately respond to queries on whether aesthetics played a role in adopting the new ordinance.

The messy items can be used without restriction on private property with the owner’s permission.

“Our ultimate goal is for everyone to be able to come and enjoy Beverly Hills and be able to trick or treat,” Drummond said.
