Even though it’s Julyuary on the west coast of Canada here (current temperature of 20C or 68F), the summer flies are alive and well. Though, due to cooler and wet conditions, the mosquitoes are particularly bad :s
One of my pet peeves is the darned house fly, also known as the “poo fly” in our house simply because they’re always seen feasting on dog poop outside.
Anyway, I think you’ll understand then why more “poo flies” would be undesirable in the house… LOL
