Florida homeowners know summer doesn’t end when the calendar flips to September. Heat, humidity, and frequent rain continue—and with them comes a surge of pests trying to escape the elements. Ants and roaches, in particular, become much more active this time of year, often making their way into kitchens, bathrooms, and garages.
In this guide, we’ll break down why these pests surge in late summer, how moisture plays a key role, and what steps you can take to protect your home.
Why Pests Surge in September
As rainfall increases and temperatures stay high, insects shift their survival strategies.
- Ants: Colonies look for dry, food-rich shelter when their nests are disturbed by heavy rains. Cracks in foundations, baseboards, and doorways make easy entry points.
- Roaches: Cockroaches thrive in warm, damp conditions. September’s moisture makes it harder for them to survive outdoors, driving them inside to kitchens and bathrooms.
- Overall pest pressure: Florida’s subtropical climate means pests reproduce year-round, but seasonal surges in late summer and early fall are especially common.
How Moisture Attracts Ants and Roaches
Moisture is the number-one factor drawing pests indoors. Common household risk zones include:
- Kitchens: Leaky faucets, pet water bowls, and food crumbs
- Bathrooms: Shower condensation, dripping pipes, and humid cabinets
- Garages and basements: Poor ventilation and damp storage areas
Once ants and roaches find a reliable water source, they often build trails or nesting zones inside, leading to recurring infestations.
Steps to Prevent September Infestations
You can reduce your chances of dealing with pests by taking a proactive approach:
1. Seal Entry Points
- Repair cracks in foundation, caulking, and weatherstripping.
- Check window screens for tears and replace as needed.
2. Control Moisture
- Fix leaking faucets and running toilets.
- Use dehumidifiers in damp areas.
- Empty pet water dishes overnight.
3. Maintain Cleanliness
- Store food in sealed containers.
- Wipe down counters daily and avoid leaving dirty dishes in the sink.
- Vacuum regularly to remove crumbs and eggs.
4. Schedule Professional Pest Services
Store-bought sprays may provide quick relief, but they rarely address colony-level infestations. Professional pest control services target both indoor and outdoor breeding zones for longer-lasting results.

Q: How quickly will professional treatments work?
A: Most treatments reduce pest activity within 24–48 hours, with full colony disruption occurring over several weeks.
