House flies are notorious for spreading disease. It’s been shown that each fly is capable of carrying more than a million bacteria. House flies are known to carry and spread diseases like cholera, conjunctivitis, dysentery, gastroenteritis, salmonellosis, tuberculosis, typhoid fever & many more.
House flies spread bacteria that contaminate your food and the surfaces where you prepare your food just by landing on them. After a house fly lands on your food, it regurgitates its stomach contents onto the food to liquefy it before ingesting your food. During feeding, house flies can also defecate on food. And remember that these flies are coming from their “homes” in garbage and animal waste.
