Flies usually enter homes in search of food, moisture, shelter, or a place to breed. Different fly species are attracted to different conditions, so identifying what is drawing them indoors can help you address the source of the problem.

Recurring fly activity may point to food residue, garbage, drains, pet waste, decaying organic material, or small openings that allow flies to enter from outside.

What Attracts Flies to Your Home?

The source depends on the type of fly you’re dealing with.

  • House Flies: Often attracted to garbage, food waste, pet waste, and other decaying organic material.
  • Fruit Flies: Commonly found around overripe fruit, vegetables, sugary liquids, recycling containers, and fermenting food residue.
  • Drain Flies: Often associated with organic buildup and moisture inside drains or other plumbing areas.
  • Cluster Flies: Usually enter buildings for shelter during cooler weather rather than because of food or sanitation conditions.

Where Are Flies Breeding?

If flies keep appearing, there may be a breeding source somewhere in or around the property.

Common areas to check include:

  • Garbage and recycling containers.
  • Kitchen spills and food residue.
  • Fruit or vegetables left out too long.
  • Drains and other moist areas.
  • Pet waste or animal activity.
  • Decaying organic material indoors or outdoors.

Removing adult flies without addressing the breeding source may only provide temporary relief.

How Do Flies Get Inside?

Flies may enter through open doors and windows, damaged screens, gaps around doors, and other small openings in the exterior of the home.

Some species, such as cluster flies, may enter through cracks around siding, rooflines, windows, or utility openings while searching for protected shelter.

How to Reduce Flies in Your Home

  • Manage food and waste: Clean up spills, store food securely, and keep trash containers covered.
  • Clean drains: Remove organic buildup from drains and moisture-prone areas.
  • Pick up pet waste: Remove animal waste from the yard regularly.
  • Repair entry points: Fix damaged screens and seal accessible gaps around doors, windows, and other openings.
  • Remove breeding material: Dispose of spoiled food, decaying organic matter, and other material that may support fly development.

When to Call a Fly Exterminator

If flies continue appearing despite cleaning and prevention efforts, the breeding source may be difficult to locate or activity may be coming from multiple areas.

Rocket Pest Control can inspect the property, identify the fly species, locate areas contributing to the problem, and recommend treatment based on the conditions present.
