When our heat turned on for the first last year, I heard of mayflies nesting in air duct before.
- I called the Heating and A/C supplier who asked me if I was sure the mayflies had come out of the air duct? They were all over our beach house and hovering on the wall over the air vent in our dining room.
I could not cook because I was afraid they would get into our food, and she told me she had never heard of mayflies in air duct, and I told her welcome to our club. I wanted the air duct cleaned and sanitized, and I wanted to guess how the mayflies got inside. She said she didn’t guess how they go inside, unless there was a crack in the air duct, and the Heating and A/C contractor would need to find that. I felt appreciate I was talking to an idiot. She didn’t have an original thought in her head. I told her to send the Heating and A/C contractor to the house. I would call an exterminator to make sure there were no other creepy crawlies hanging out in the air duct, and then their Heating and A/C supplier could repair, clean, and sanitize our air duct. She was smiling while talking and told me that was smart thinking. She wished she had thought to tell me that. The exterminator was at the beach house the next day, and the Heating and A/C contractor arrived the same day. He called to have the air duct cleaners come to the house. He had found several small cracks in the air duct, however nothing the air duct cleaners could not repair. Within several days, the mayflies were gone, and our air duct had been cleaned, repaired, and sanitized.
