Why You Have House Flies

Nothing’s more annoying than a house fly buzzing in circles while you’re trying to eat, watch TV, or cook. You swat at it, it disappears, and five minutes later—it’s back. If that sounds familiar, you’re not alone. House flies are one of the most common pests in Rialto, Fontana, and across Southern California, especially during the warmer months.
Let’s talk about why you have them, what they’re doing inside your home, and why it’s important to take them seriously before they multiply.
Why You Have House Flies
House flies don’t just wander in for fun. They’re there for a reason.
Flies are attracted to:
Food odors
Trash bins
Pet waste
Rotting fruit or vegetables
Moisture and organic buildup
If they’re in your home, there’s likely something they’re feeding on—even if it’s small, like crumbs under an appliance or liquid in a trash can. They can smell these things from far away, and once they find them, they move in fast.
Even a door left open for a few seconds can be an open invitation for flies looking for food, warmth, and a place to breed.
What Flies Are Looking For Inside Your Home
Once they’re inside, flies look for:
Food: Anything left uncovered, including pet food.
Water: Sinks, drains, and even condensation.
Breeding sites: Trash cans, compost bins, or dirty mop water.
Female flies lay eggs in moist, decaying organic material—like garbage or spoiled food. Those eggs hatch into maggots within a day. That means one missed piece of food waste can turn into dozens of flies by the end of the week.
Why You Should Get Rid of House Flies
House flies aren’t just annoying—they’re dirty. Every time they land, they can transfer bacteria from wherever they’ve been before.
Common diseases linked to house flies include:
Salmonella
E. coli
Staph infections
They pick up these pathogens from trash, feces, or animal carcasses and spread them to surfaces, food, and utensils. So even though they don’t bite, they’re still a serious health risk.
The longer you wait, the faster they breed. One fly can lay up to 500 eggs in her short lifetime, which means an infestation can get out of hand quickly.
How to Get Rid of House Flies
Here’s how to make your home less attractive to flies:
Seal trash cans tightly and empty them often.
Clean up spills right away, especially sugary drinks.
Keep drains clean with regular enzyme treatments.
Cover food and don’t leave pet food out overnight.
Fix screens and seal gaps around doors and windows.
If you already have a heavy fly problem, DIY methods like sprays or traps might give short-term relief—but they don’t stop the breeding. That’s where professional pest control comes in.
