Have you ever been on an outing where you were looking forward to sharing some wine with superb friends at a local park or nature reserve? The weather is perfect, & all the people is in a superb mood, but no a single bothered to bring a corkscrew to open that special vintage you had been saving for the occasion, and the lack of the implement becomes the “fly in the ointment”, a small thing that can potentially ruin the event, and i’m amused by that trite saying because I’ve never known flies to be attracted to salves & creams.
If a fly alights in a jar of skin cream, how can it possibly ruin the entire contents of the jar? Flies are a dangerous pest when they get inside the house & begin to look for food, a place to sit their eggs, & to carry on their other disgusting activities that flies are well known for, fly swatters, flypaper, pesticides, & vinegar are all ways to get rid of flies but another way to control them is with your home’s HVAC systemâ€¦ Note that the word used in the previous sentence is to “control” instead of “kill” because even the best AC cannot produce the hot & cold temperatures needed to kill them.
The best thing an HVAC method can do is slow them down a bit with their breeding & buzzing. Flies love hot & cold temperatures between 20°C to 25°C (73°F to 75°F) but they can breed quite abruptly in warmer environments up to 38°C (100°F). At 15°C (29°F) they stop all activity. The better solution is to prevent them from getting inside the house in the first place. It’s also wise to keep your HVAC in a fly free condition with twice-yearly repair & cleaning by a qualified HVAC business.
