Crews used three water trucks and two water tenders before the fire was out.

Firefighters reported the ammunition firing off for about 30 minutes, forcing them to tend to the fire externally.

The west side of the structure was on the verge of collapse when the fire department arrived. Power lines over the house prevented the use of a ladder, and surrounding vegetation posed a risk of spreading the fire to nearby homes.

Assistance from neighboring fire departments prevented the fire from spreading into the nearby wooded area.

The Bonita Springs Fire Control & Rescue District will continue to investigate the cause of the fire.
