Why Cockroaches Are Still Active in September

Cockroach on a plate

Even as summer heat begins to wane, cockroaches can remain very active in September. These resilient pests seek warmth, water, and food, making homes in Phoenix ideal shelters as outdoor temperatures fluctuate.

Don’t let cockroach activity get out of control — contact us today or call (877) 735-9189 to explore safe solutions for your home.

Common Reasons Cockroaches Stay Active

1. Warm Indoor Environments

Cockroaches thrive in temperatures between 70°F and 85°F. Homes that maintain warmth with air conditioning or residual summer heat provide ideal conditions.

  • Kitchens and bathrooms are particularly attractive due to water and food access.
  • Warm, dark areas, such as cabinets, behind appliances, and attics, offer safe hiding spots.

2. Food and Water Sources

Even small crumbs or moisture can sustain cockroaches:

  • Pet food left out overnight or unsealed pantry items draw them indoors.
  • Leaky faucets or condensation provide a consistent water source.
  • Trash bins without tight lids are another common attractant.

3. Shelter From Outdoor Changes

September brings slightly cooler nights and occasional rains, prompting cockroaches to move indoors for stability.

  • They can enter through cracks in doors, windows, vents, and plumbing openings.
  • Commercial and residential properties near mulch or compost may see higher activity.

Tips to Reduce Cockroach Activity

  1. Seal Entry Points
  • Caulk cracks around doors, windows, and baseboards.
  • Inspect and repair gaps near plumbing or utility access points.
  1. Keep Food and Water Secure
  • Store pantry items in sealed containers.
  • Clean crumbs and spills promptly.
  • Fix leaky pipes and remove standing water.
  1. Reduce Clutter and Hiding Spots
  • Clear out unused boxes, paper piles, and storage near kitchens.
  • Keep cabinets organized and dry.
  1. Regular Inspections
  • Check behind appliances, under sinks, and in dark corners regularly.
  • Pest control in Phoenix can help identify hidden activity and implement effective treatment plans.

Seasonal Awareness

Even as temperatures drop slightly, cockroaches remain a risk throughout September. Early fall is the perfect time to implement preventive measures before the cooler months encourage more indoor activity. Consistent cleaning, sealing, and monitoring help reduce the likelihood of infestations.
