Yesterday afternoon, while my family was away, there was a fire adjacent to my bees. The bees do not seem to be adversely affected and the hives did not burn. My neighbor noticed it and put it out with his fire extinguisher before the fire department arrived to finish the job. The cause of the fire is unknown. Although I am grateful for my neighbor and his efforts, do I need to be concerned about the use of a chemical fire extinguisher? In my mind it is better to stop the fire by any means than worry about chemical exposure to my bees. I'm just curious if the chemicals could harm them. It was your basic home chemical extinguisher.
