Kids in Halloween Customscross the street near the scene where a man driving a rental truck struck and killed eight people on a jogging and bike path in Lower Manhattan on October 31, 2017 in New York City.

Today could be scarier for your budget than anticipated: Halloween is one of the worst days of the year for homeowners and auto insurance claims.

On average, Halloween has 17 percent more home claims for theft, vandalism and other crimes than any other day of the year, according to a new assessment from Travelers.

That includes problems like doors kicked in, mailboxes knocked down and rocks thrown through windows, said Angi Orbann, vice president of personal insurance property for Travelers. In some cases, damage can run into thousands of dollars.

Data from the Highway Loss Data Institute found a similar boost among auto insurance claims over the 2008 to 2012 period, citing Halloween as the day of the year with the highest average number of auto insurance claims for vandalism — almost twice as many as the typical day. (A spokesman said that trend still holds.)

Spookier: Damage bills may be even more prevalent than those numbers imply.

Homeowner policies, for example, often have a deductible of $500 to $1,000 before coverage kicks in. So acts of theft or vandalism that fall shy of that threshold (meaning you shoulder that expense and don't file a claim) aren't included in the numbers, said Orbann.

And in some areas, the evening before Halloween — aka Devil's Night, Mischief Night and other variants — is better known for such pranks. Halloween claims data likely include damage from that night discovered Halloween morning, she said, although Travelers also noted a slight jump in claims on Oct. 30.

The first step to limiting Halloween insurance scares is checking your insurance policy for potential gaps, said Michael Barry, a spokesman for the Insurance Information Institute. A typical homeowners policy would cover theft and vandalism, but you should make sure you're comfortable with your deductible.

Liability coverage, should a trick-or-treater or other visitor be hurt on your property, is another consideration.

"There may not be only bodily injury and property damage, but there can also be a lawsuit," he said.

With auto insurance, weigh comprehensive coverage, which encompasses a wide range of damage including vandalism and theft of auto parts, Barry said. About 8 in 10 drivers have it, and for those who don't, it can be cheap peace of mind.
