At least 37 giant live beetles measuring 4 to 5 inches have been found concealed inside of multiple packages of Japanese snacks, potato chips and chocolate at LAX.

On the East Coast, a similar discovery was made at John F. Kennedy International Airport in Queens, New York, according to the agency. Inside a package from Japan, agency specialists found six live beetles hidden in food packages on Jan. 16, the agency’s Office of Field Operations said in a Feb. 3 news release.

Over three dozen live beetles concealed inside packages of Japanese snacks were discovered by US Customs and Border Protection at the Los Angeles International Airport last month.
