Seasonal Pest Calendar for Chattanooga & Southeast Tennessee
Seasonal Pest Calendar for Chattanooga & Southeast Tennessee

Chattanooga and Southeast Tennessee’s mild winters, humid summers, and frequent rainfall create the perfect environment for pests year-round. While many homeowners think of pest control as a seasonal concern, the truth is that different pests are active during every month of the year.
Understanding when pests are most active helps homeowners stay proactive, prevent infestations, and protect their homes before problems escalate. Below is a season-by-season pest calendar tailored specifically to Chattanooga and Southeast Tennessee.
Spring (March – May): Pest Activity Begins
As temperatures rise and rain becomes more frequent, pests emerge in search of food, moisture, and nesting areas.
Common Spring Pests:
- Ants
- Termites (swarm season)
- Spiders
- Wasps & hornets
- Mosquitoes (late spring)
Why Spring Pest Control Matters:
Spring is one of the most important times for pest prevention. Termite swarms often occur during this season, and ants begin invading kitchens and bathrooms. Moisture from spring rains can also drive pests indoors.
Recommended Action:
- Schedule a termite inspection
- Begin preventative pest control treatments
- Seal cracks, windows, and entry points
- Address standing water around the home
Summer (June – August): Peak Pest Season
Summer brings high humidity and heat — ideal conditions for rapid pest reproduction. This is when infestations can grow quickly if left untreated.
Common Summer Pests:
- Mosquitoes
- Cockroaches
- Ants
- Fleas & ticks
- Stinging insects (wasps, yellow jackets)
Why Summer Pest Control Matters:
Mosquitoes thrive in Chattanooga’s humid climate, while cockroaches seek shelter indoors to escape heat. Outdoor activities also increase exposure to ticks and fleas, especially for pet owners.
Recommended Action:
- Ongoing pest control service
- Mosquito treatments for yards
- Reduce moisture and standing water
- Keep trash and food sealed properly
Fall (September – November): Pests Seek Shelter
As temperatures cool, many pests look for warmth indoors — making fall a critical time for exclusion and prevention.
Common Fall Pests:
- Rodents (mice & rats)
- Spiders
- Stink bugs
- Boxelder bugs
- Crickets
Why Fall Pest Control Matters:
Rodents often enter homes through small gaps in foundations, crawlspaces, and attics. Once inside, they can cause structural damage and contaminate food.
Recommended Action:
- Rodent inspections and exclusion services
- Seal entry points around foundations and vents
- Clean crawlspaces and attics
- Maintain exterior pest barriers
Winter (December – February): Hidden Pest Problems
Even during colder months, pests don’t disappear — they simply move indoors or remain hidden.
Common Winter Pests:
- Rodents
- Cockroaches
- Spiders
- Silverfish
Why Winter Pest Control Matters:
Winter infestations often go unnoticed until they become severe. Rodents can chew wiring and insulation, while cockroaches thrive in warm, indoor environments.
Recommended Action:
- Year-round pest control plans
- Interior inspections
- Moisture control in crawlspaces and basements
- Address small infestations before spring
Why Chattanooga Homes Are More Vulnerable to Pests
Homes in Southeast Tennessee face unique pest pressures due to:
- High humidity levels
- Crawlspace foundations
- Dense tree coverage
- Mild winters that allow pests to survive year-round
Without consistent pest control, these conditions make infestations more likely — even in well-maintained homes.
