Mirroring a national trend, Delaware fire officials said the use of illegal fireworks is blowing up.
"We're getting hundreds of calls, complaints actually, from residents of Delaware complaining about the fireworks," said Delaware State Fire Marshals' Office spokesman Mike Chionchio. "I've gotten reports since early April.
"They continue to go off at all times of the day and night. [We've gotten] several complaints that they're occurring after midnight."
In Delaware only sparklers and ground-based fireworks are legal and that's only for four days a year - July 4th, New Year's Eve, New Year's Day, and one day during the Diwali holiday in November.
Chionchio said these aren't small fireworks that are being lit off, they are professional grade and shouldn't be in the hands of amateurs for fear they may blow some fingers off, or worse.
"We're talking about fireworks that shoot up into the air and launch from somebody's house or somebody's backyard and end up five blocks down the street," said Chionchio.
