November brings cooler temperatures across Louisiana and Texas, but don’t let the chill fool you. As outdoor conditions become less hospitable, pests seek warmth and shelter—often finding it inside your home or business. Understanding which pests are most active during this month can help you take proactive steps to protect your property.

At J&J Exterminating, we’ve spent over 65 years helping families and businesses across Louisiana and Texas deal with seasonal pest challenges. This guide will walk you through the most common November pests in our region and explain how our proven methods can keep your property pest-free through fall and winter.

Why November Is Prime Time for Pest Activity

November marks a transition period for many pests. The combination of dropping temperatures and reduced food sources outdoors drives insects and rodents to seek indoor environments. Your home offers everything they need: warmth, food, water, and shelter.

Commercial properties face similar challenges, particularly in food service, warehousing, and hospitality industries. A single pest sighting can damage your reputation and lead to health code violations. That’s why prevention becomes critical as we move into the cooler months.

Rodents: The Most Persistent November Problem

Mice and rats become particularly aggressive in their search for indoor shelter during November. A single mouse can squeeze through an opening as small as a dime, while rats need only a quarter-sized gap to enter your property.

Signs of Rodent Activity

Watch for these warning signs:

• Droppings near food sources or in hidden areas
• Gnaw marks on wood, wires, or food packaging
• Scratching sounds in walls or ceilings, especially at night
• Grease marks along walls where rodents travel
• Nests made from shredded paper or fabric

Health and Safety Risks

Rodents aren’t just a nuisance. They carry diseases like hantavirus and salmonella, contaminate food supplies, and cause structural damage by chewing through electrical wiring. The CDC estimates that rodents invade approximately 21 million American homes each winter.

How J&J Exterminating Controls Rodents

Our rodent control approach combines multiple strategies for maximum effectiveness:

Exclusion Methods: We identify and seal entry points to prevent rodents from accessing your property. This might include installing door sweeps, sealing gaps around pipes, and repairing damaged vents.

Baiting and Trapping: We strategically place bait stations and traps in areas of high activity. Our products are AIB certified and meet USDA and FDA regulations for commercial applications.

Monitoring: We don’t just treat the problem once and disappear. Our Gold Shield 365 program includes regular monitoring to ensure rodents don’t return.

Cockroaches Seeking Indoor Warmth

Several cockroach species become more visible in November as they move indoors. German cockroaches, American cockroaches, and Oriental cockroaches all seek the warmth and moisture found in kitchens, bathrooms, and basements.

Why Cockroaches Are Problematic

Beyond being unsettling to encounter, cockroaches pose genuine health risks. They spread bacteria, trigger allergies and asthma, and multiply rapidly. A single female German cockroach can produce up to 30,000 offspring in one year.

J&J’s Integrated Pest Management Approach

We use Integrated Pest Management (IPM) techniques that focus on long-term prevention rather than just quick fixes:

• Sanitation recommendations to eliminate food and water sources
• Residual barriers applied to common entry points and harborage areas
• Baiting programs using products that target entire colonies
• Physical exclusion to block access routes

Our methods use fewer products overall while delivering more effective, lasting results.

Spiders Moving Inside for Winter

As outdoor insects become scarce, spiders follow their food sources indoors. While most spiders are harmless, some species like the brown recluse can pose health risks. Even harmless spiders can create unsightly webs and cause anxiety for residents or customers.

Common Indoor Spiders in November

• House spiders: Build messy cobwebs in corners and unused spaces
• Wolf spiders: Large, fast-moving spiders that don’t build webs
• Brown recluse: Venomous spiders that prefer dark, undisturbed areas
• Cellar spiders: Create tangled webs in basements and crawl spaces

Our Spider Control Solutions

J&J Exterminating addresses spider problems by:

• Treating areas where spiders hide and build webs
• Reducing the insect populations that attract spiders
• Sealing entry points to prevent future infestations
• Providing exterior treatments to create a protective barrier

Ants Still Active in Mild November Weather

Louisiana and Texas often experience mild November temperatures, allowing ants to remain active longer than in colder climates. Carpenter ants, fire ants, and odorous house ants commonly invade structures during this time.

Carpenter Ants and Structural Damage

Carpenter ants deserve special attention because they excavate wood to create nesting galleries. While they don’t eat wood like termites, they can still cause significant structural damage over time. November’s moisture from fall rains can make wood more attractive to these pests.

J&J’s Ant Control Methods

Our ant treatments vary based on the species but typically include:

• Identification of the specific ant species (different species require different approaches)
• Location and treatment of outdoor colonies
• Interior baiting to eliminate colonies at their source
• Perimeter treatments to prevent entry
• Moisture control recommendations to reduce attractants

Stink Bugs Seeking Shelter

Brown marmorated stink bugs become particularly problematic in November as they search for overwintering sites. These shield-shaped insects congregate in large numbers on sunny sides of buildings before finding their way inside through cracks and gaps.

The Challenge with Stink Bugs

Stink bugs earned their name for good reason. When disturbed or crushed, they release a foul odor. Once inside, they hide in walls, attics, and other voids, emerging on warm days to fly around rooms.

Professional Stink Bug Prevention

J&J Exterminating handles stink bug invasions through:

• Exterior treatments applied before stink bugs enter structures
• Sealing of entry points around windows, doors, and siding
• Removal of existing populations
• Ongoing monitoring during peak season

Termites: The Year-Round Threat

While termites are active year-round in Louisiana and Texas, November is an excellent time to schedule a termite inspection. Cooler weather makes some signs of infestation more visible, and treating before spring swarming season provides maximum protection.

Two Proven Termite Control Systems

J&J Exterminating offers two highly effective termite control options:

The Termidor System: Creates a treated zone in the soil around your property. Termites can’t detect it, so they travel through the treatment zone and spread it to colony members, eliminating the entire colony.

The Sentricon System: Uses monitoring and baiting stations installed directly in the ground. Termites prefer the bait over wood, consume it, and share it with the colony. This system has protected the Statue of Liberty and millions of homes worldwide.

Your technician will assess your property and recommend the best protection based on your specific situation.
