September Pests in Tennessee: What Homeowners Should Watch For

As summer heat fades and cooler September days arrive in Tennessee, pests begin shifting their habits. While some slow down as temperatures drop, many others go on the move—seeking food, water, and warmth inside homes. If you want to avoid a fall infestation, here’s what you should know about early fall invaders and how to protect your home.

Why Pest Activity Surges in September

Several seasonal changes make September a peak time for pests in Tennessee:

• Cooler nights → Pests leave outdoor shelters that no longer provide enough warmth.

• Dry conditions → With less water outside, pests look indoors for steady moisture sources like sinks, pet bowls, and humid bathrooms.

• Breeding season → Spiders and other pests become more active as they search for mates.

• Food scarcity → As gardens fade and plants die off, pests head indoors in search of a reliable food source.

Together, these factors create the perfect storm for pests to sneak inside.

Common September Pests in Tennessee Homes

These are the most common fall invaders homeowners report in Middle Tennessee:

• Spiders – More visible in the fall as males roam in search of mates. Many end up indoors seeking warmth.

• Stink bugs – Cluster on sunny walls before squeezing into attics and wall voids to overwinter.

• Boxelder bugs – Often found near windows, doors, and siding while searching for warmth.

• Ants – Move indoors looking for food and potential nesting sites.

• Cockroaches – Thrive in warm, damp indoor environments with plenty of food sources.

• Crickets – Seek indoor shelter as nights get colder, bringing their loud chirping with them.

• Rodents – Mice and rats move inside for warmth, steady food, and water, quickly turning into destructive houseguests.

Signs That Pests Are Creeping In

Wondering if pests have already made their way inside? Keep an eye out for these warning signs:

• Live or dead pests indoors

• Bugs around windows, baseboards, or crawlspaces

• Droppings, egg sacs, or spider webs

• Unexplained foul odors (e.g., from stink bugs or rodents)

• Scratching, chewing, or chirping sounds at night

• Damaged food packaging, fabrics, or houseplants

The sooner you spot these signs, the faster you can take action before an infestation spreads.

Simple Steps to Prevent a Fall Infestation

Proactive prevention goes a long way in keeping pests out. Here’s what you can do now:

• Seal cracks around windows, doors, and foundations

• Repair screens and replace worn weatherstripping

• Keep firewood, mulch, and debris away from siding

• Wipe up crumbs, trash, and standing water promptly

• Vacuum regularly and monitor high-risk entry points

• Run dehumidifiers in basements or crawl spaces

• Trim foliage and keep lawns tidy to reduce hiding spots

When to Call a Pest Control Professional

Sometimes, DIY prevention isn’t enough. It’s time to call a pest control expert if:

• You’re seeing pests repeatedly indoors

• Suspected nests are in hard-to-reach spaces (attics, vents, or wall voids)

• Past DIY methods haven’t worked

• You want year-round protection and peace of mind
