Top 5 Pests in Central Texas During Rainy Periods (and How to Keep Them Out!)

Rain in Central Texas is both a blessing and a challenge. While the showers refresh our landscapes, they also create ideal conditions for certain pests to thrive. Increased moisture, humidity, and standing water become breeding grounds for unwelcome critters, driving them into homes and gardens. Here’s a rundown of the top five pests you’ll likely encounter during rainy periods and tips to protect your property.


1. Mosquitoes

Why They Thrive
Rain equals standing water, the perfect breeding ground for mosquitoes. Even a small puddle or clogged gutter can support hundreds of larvae.

Why They’re a Problem
Mosquitoes aren’t just annoying—they’re carriers of diseases like West Nile Virus and Zika.

How to Prevent Them

  • Drain Standing Water: Empty buckets, flowerpot saucers, and other water-collecting items.
  • Use Mosquito Repellent Plants: Lemongrass and lavender are natural deterrents.
  • Maintain Your Yard: Keep grass short and bushes trimmed to reduce shady resting spots.

2. Fire Ants

Why They Thrive
Rain causes fire ant colonies to relocate to higher ground, often leading them into yards and homes.

Why They’re a Problem
These aggressive pests deliver painful stings, making them particularly dangerous for pets and children.

How to Prevent Them

  • Seal Cracks and Gaps: Inspect your home’s foundation and seal any entry points.
  • Use Bait Treatments: Apply fire ant bait around your yard to curb infestations.
  • Avoid Disturbing Mounds: This could make the ants more aggressive and disperse the colony.

3. Termites

Why They Thrive
Moisture softens wood, making it easier for termites to feed and establish colonies. Swarm activity often increases after rain.

Why They’re a Problem
Termites can cause severe structural damage if left unchecked.

How to Prevent Them

  • Fix Leaks Quickly: Ensure gutters and downspouts direct water away from your foundation.
  • Store Wood Properly: Keep firewood and mulch at least 20 feet away from your home.
  • Schedule Inspections: Regular pest control inspections can catch problems early.

4. Cockroaches

Why They Thrive
Heavy rains often drive cockroaches indoors seeking shelter. Damp basements and kitchens are their favorite hiding spots.

Why They’re a Problem
Cockroaches are unhygienic, spreading bacteria and allergens that can trigger asthma.

How to Prevent Them

  • Keep It Clean: Eliminate food crumbs and standing water.
  • Seal Entry Points: Use caulking to block cracks around doors and windows.
  • Set Traps: Sticky traps and gel baits are effective in controlling infestations.

5. Spiders

Why They Thrive
Rain pushes spiders out of their hiding spots and into homes. Increased insect activity also attracts spiders.

Why They’re a Problem
While most spiders are harmless, some species like the black widow or brown recluse pose health risks.

How to Prevent Them

  • Declutter: Clear away boxes and unused items where spiders can hide.
  • Remove Webs: Regularly sweep away cobwebs to discourage spiders from staying.
  • Use Essential Oils: Peppermint oil is a natural spider repellent.

Final Thoughts

Rainy periods in Central Texas may bring challenges, but with some proactive measures, you can minimize the impact of these pesky intruders. Regular yard maintenance, sealing entry points, and professional pest control services can make all the difference.

By keeping your home and yard pest-free, you can enjoy the rain without the annoyance (or risk) of these uninvited guests!
