September Pest Watch: What to Expect This Month

September in Texas is a month of transition. The days are still warm, but nights begin to cool, and the shift in temperature sends a clear message to the insect and rodent world: change is coming. Some pests are finishing their seasonal cycles, while others are gearing up for winter by moving closer to our homes, gardens, and businesses.

For homeowners, this makes September one of the most active pest months of the year. Here’s a look at the key troublemakers you should be watching for — and how to stay one step ahead of them.

Crickets: The Seasonal Swarm

If you’ve noticed sidewalks, porches, and storefronts suddenly coated in hopping insects, you’re not imagining things. September is cricket season in Texas. Their life cycle peaks now, and cooler nights trigger swarming behavior around lights and damp areas.

What makes them a problem:

• Large numbers pile up around doors and windows.

• Indoors, they chew fabrics, paper, and wallpaper.

• Dead crickets smell and attract secondary pests.

• Their constant chirping disrupts sleep.

What to do: Switch to yellow outdoor bulbs, seal entry points, and keep lawns trimmed to reduce hiding spots.

Wasps and Yellowjackets: Aggressive and Hungry

By September, colonies are at their largest. At the same time, natural food sources decline. That combination makes wasps and yellowjackets more aggressive, more desperate, and more likely to bother you during outdoor activities.

Common scenarios:

• Hovering near cookouts, trash bins, or sugary drinks.

• Building nests in eaves, sheds, or playground equipment.

• Attacking when nests are disturbed, even accidentally.

What to do: Avoid DIY nest removal — it’s dangerous. Professional removal ensures safety and prevents colonies from rebuilding.

Spiders: More Sightings Indoors

While most spiders are harmless, September is mating season, so males wander in search of females. This leads to more sightings in basements, garages, bathrooms, and bedrooms.

Why it matters:

• Even harmless species make homeowners uneasy.

• Some species, like brown recluse or black widow, pose health risks.

• Spider webs in corners and windows create an unkempt appearance.

What to do: Vacuum webs regularly, reduce indoor clutter, and seal cracks around windows and doors to limit entry.

Rodents: Looking for Shelter Early

Cooler nights in September send rodents scouting for food and warmth. Attics, garages, and pantries make perfect shelters. If they find entry points, you could be hosting unwanted guests before winter even begins.

The risks:

• Chewed wires that can cause fire hazards.

• Contaminated food supplies in kitchens and pantries.

• Rapid reproduction that turns one or two rodents into dozens.

What to do: Inspect for gaps the size of a dime (mice) or quarter (rats) around your foundation. Seal with steel wool or hardware cloth, and keep food sealed tightly.

Chiggers and Aphids: Still Active Outdoors

Even as summer fades, two small pests continue to cause big frustration.

• Chiggers thrive in tall grass and cause intensely itchy bites that linger for days. They’re especially active when families are still enjoying football games, hikes, and backyard cookouts.

• Aphids are garden destroyers, leaving behind sticky honeydew, black sooty mold, and damaged fall plants. They’re particularly tough on flowers, vegetables, and even shrubs in September.

Why September Pest Control Is Critical

September is the bridge month. Pests are either peaking in population or moving indoors to prepare for cooler months. Addressing infestations now prevents headaches later: fewer crickets chirping, fewer rodents nesting, fewer wasps stinging, and a smoother transition into fall.
