Two crews from Lichfield were called to a bungalow on Havefield Avenue in Boley Park, Lichfield at just after midnight on Friday night, following reports a firework had been pushed through a letterbox.
"Whoever did this needs to realise it is a very silly thing to do, fireworks are not toys and should not be treated like they are."

Staffordshire Police were also in attendance at the incident, which has caused minor damage to the property hallway and scorched the carpet.
Watch Manager, Steve Whitehouse said: "Luckily, the occupants had working smoke alarms which alerted them to the incident. The firework had been jammed through the letterbox which prevented a large explosion, however the occupants could have found themselves with no means of escape if it had set fire to nearby combustible materials.
"Whoever did this needs to realise it is a very silly thing to do, fireworks are not toys and should not be treated like they are – they can fatally injure people if not used safely and appropriately. Staffordshire Fire and Rescue Service are currently visiting schools across the county as part of our Operation Good Guy campaign to give presentations and demonstrations on fireworks to show just how dangerous they can be.
"Operation Good Guy is a timely reminder to children and young people to think about the dangers of fireworks in the hope they can develop a healthy respect for fireworks and be safe at all times."
Staffordshire Police are investigating the incident and anyone with information is asked to contact Staffordshire Police on 0300 123 44 55 or alternatively people can contact Crimestoppers anonymously on 0800 555 111.
Crews left the incident at 12.30am.
