How Cooler Nights in Tennessee Drive Pests Inside

It’s that time of year again! Warm days are giving way to cooler nights, finally giving us all a break from the relentless summer heat. Whether you’re someone who loves crisp fall evenings or you’re already missing the warmth, there’s one thing about this season that most of us can agree on — fall tends to bring more pest activity.

As temperatures drop, many Tennessee pests start heading indoors. And after more than 60 years in pest control, we at All-American Pest Control have seen our fair share of fall infestations! So, we’re here to share what we’ve learned,  including why pests move in this time of year, what you can do to stop them, and when it’s best to call in the pros.

Why Cooler Nights Change Pest Behavior

Pests are surprisingly in tune with the changing seasons; they have to be if they want to survive! As the nights start cooling down, pests get the message that it’s time to find warmth and shelter. They know their outdoor homes won’t offer enough protection once winter really sets in.

Fall also brings fewer food options outdoors. Insect-eating pests can’t find as many bugs to munch on, while those that rely on plants, seeds, or fruits have a harder time finding a meal as vegetation dies off.

When the nights get chilly, pests start looking for safe, cozy places where food and warmth are easy to find, and unfortunately, that often means our homes.

Pests on the Move During Fall Evenings

So, which pests are most likely to show up in or around your Tennessee home this fall? Here are a few usual suspects you might notice seeking shelter:

• Spiders – They become more active at dusk, hunting insects drawn to porch or indoor lights.

• Ants – As the weather cools, ants go exploring for new indoor food sources and nesting areas.

• Stink bugs and boxelder bugs – These seasonal pests love sunny walls and sneak inside through cracks and gaps.

• Cockroaches – Roaches seek warmth and moisture, so they often end up in kitchens, bathrooms, and basements.

• Rodents – Mice and rats are classic fall invaders, slipping into walls, attics, and pantries to stay warm and well-fed.

• Crickets and other insects – Since many can’t survive the cold, they look for any way inside through vents and small openings.

Telltale Signs Pests Are Entering at Night

Most pests are nocturnal, meaning they’re busiest while we’re asleep. You might not see much activity during the day, but knowing the signs of an infestation can save you a lot of trouble and protect your family from potential health issues or home damage. Watch for these red flags:

• Webs or insects near windows, lights, or door frames

• Droppings or tracks in basements, crawlspaces, or along walls

• Rustling, scratching, or movement behind walls or ceilings

• A sudden increase in live insects indoors

• Musty or unpleasant odors

What You Should Do Right Now to Prevent Indoor Pest Trouble

So far, this might sound like bad news; pests are on the move, and they’ve got your home on their radar. But don’t worry! With some smart prevention steps (and a little professional pest control backup), you can stop infestations before they start.

Here are a few things you can do right now:

• Seal cracks, gaps, and openings around your foundation and siding

• Check weather stripping and door sweeps; replace if they’re worn out

• Screen vents, roofline penetrations, and windows

• Keep firewood, mulch, and debris away from your exterior walls

• Turn off unnecessary outdoor lights or switch to bug-friendly bulbs

• Keep things tidy indoors meaning vacuum regularly, clean up crumbs and spills, store food properly, and cut down on clutter

• Use dehumidifiers or improve ventilation in damp areas

• Fix leaks or other moisture issues inside and outside your home

Lower-Light & Outdoor Lighting Tips to Reduce Insect Attraction

You might be wondering, what does lighting have to do with pests? Quite a bit, actually! Many insects are drawn to light, especially at night when it’s dark everywhere else. If you leave porch lights on or have bright windows, it’s basically an open invitation for bugs.

That’s why spiders love hanging out near outdoor lights; it’s an easy dinner spot for them. Luckily, a few simple lighting tweaks can make a big difference:

• Use yellow “bug lights” or sodium vapor bulbs that don’t attract insects

• Limit lighting near doors, eaves, and windows

• Angle lights downward or add shields

• Switch to motion-activated lights instead of ones that stay on all night

• Close blinds or curtains when your indoor lights are on

When DIY Doesn’t Cut It — Call a Pest Control Expert

Even with great prevention habits, sometimes pests still find a way in. Here’s how to know when it’s time to bring in the professionals:

• You’re still seeing pests after sealing and cleaning

• The infestation seems hidden (like in attics, crawlspaces, or walls)

• You’ve noticed damage or signs that pests could cause harm to your home

• You’d simply like peace of mind with a fall inspection or perimeter pest control treatments
