The Top 10 Pests Every Texan Needs to Watch Out For

1. Fire Ants

Identification: Fire ants are small, reddish-brown insects that build noticeable mounds in yards and open areas. Their colonies can number in the thousands, making them especially aggressive when disturbed.

Risks:

• Painful stings that can lead to itching, swelling, or even severe allergic reactions.
• Structural damage as they tunnel near foundations.
• Disruption of native wildlife, as they compete for resources.

Prevention:

• Inspect yards regularly for new mounds.
• Use targeted baits that fire ants carry back to their colonies.
• Consider professional mound treatments if infestations are widespread.

2. Termites

Types: Texans mainly encounter subterranean and drywood termites. Subterranean termites typically nest in soil, while drywood termites inhabit wooden structures.

Risks:

• Serious structural damage that can remain hidden until repairs become costly.
• Each year, termites are responsible for billions of dollars in property damage nationwide.

Prevention:

• Schedule annual inspections with a licensed professional.
• Control moisture levels around the home by fixing leaks and ensuring proper drainage.
• Opt for termite-resistant materials when building or renovating.

3. Cockroaches

Common Species: German, American, and Oriental cockroaches are frequently found in Texas homes and buildings.

Risks:

• Spreading bacteria like salmonella and E. coli.
• Triggering asthma and allergies in sensitive individuals.

Prevention:

• Seal cracks around doors, windows, and foundations.
• Eliminate food sources by storing items in airtight containers and cleaning up crumbs.
• Consider roach baits or traps for minor problems, and call a professional if infestations persist.

4. Mosquitoes

Key Species: Aedes aegypti (often associated with Zika and dengue) and Culex pipiens (commonly linked with West Nile virus).

Risks:

• Transmission of illnesses such as West Nile and Zika viruses.
• Persistent itching and discomfort from bites.

Prevention:

• Remove standing water in buckets, birdbaths, or gutters.
• Install or repair window screens to keep mosquitoes out of living spaces.
• Use EPA-approved repellents containing DEET, picaridin, or oil of lemon eucalyptus.

5. Rodents (Mice & Rats)

Signs: Look for droppings, gnaw marks on wood or wiring, and noises in walls or attics—especially at night.

Risks:

• Contamination of food and living areas.
• Disease transmission (e.g., hantavirus, leptospirosis).
• Property damage from constant gnawing.

Prevention:

• Seal all entry points, including gaps around pipes and doors.
• Store food in airtight containers and avoid leaving pet food out.
• Set traps and check them regularly, or consult a rodent control professional for larger infestations.

6. Venomous Spiders

Key Species:

• Black Widows: Identified by a red hourglass marking on the abdomen.
• Brown Recluses: Noted for a violin-shaped mark on the back.

Risks:

• Bites can cause necrotic lesions or severe allergic reactions.
• Children and elderly individuals may experience more serious complications.

Prevention:

• Keep clutter to a minimum in garages, sheds, and crawl spaces.
• Seal cracks and crevices around windows and doors.
• Use sticky traps along baseboards, especially in dark corners.

7. Scorpions

Common Species: The striped bark scorpion is the most common in Texas.

Risks:

• Painful stings, sometimes leading to numbness or swelling.
• Severe allergic reactions in some individuals.

Prevention:

• Trim vegetation away from the house to reduce hiding spots.
• Shake out shoes, clothing, or bedding before use.
• Schedule perimeter treatments to keep scorpions from entering the home.

8. Wasps & Bees

Types: Yellow jackets, hornets, and honey bees frequently nest around homes.

Risks:

• Stings can be aggressive, leading to pain, swelling, and potential allergic reactions.
• Nests may form inside walls or attics, making removal challenging.

Prevention:

• Remove small nests early before colonies expand.
• Avoid wearing strong fragrances or bright colors that attract these insects.
• For large nests, consult a professional for safe removal.

9. Fleas & Ticks

Risks:

• Fleas can cause anemia in pets and can lead to itchy bites on humans.
• Ticks spread serious illnesses like Lyme disease and Rocky Mountain spotted fever.

Prevention:

• Treat pets regularly with veterinarian-approved flea and tick preventatives.
• Vacuum carpets and upholstery often to remove eggs and larvae.
• Mow lawns and keep outdoor areas tidy to discourage infestation.

10. Bed Bugs

Signs: Small bloodstains on sheets, fecal spots near mattress seams, and itchy, clustered bites on skin.

Risks:

• Rapid and hard-to-control infestations that spread easily through luggage and personal belongings.
• Psychological stress, sleep disturbances, and potential allergic reactions.

Prevention:

• Inspect luggage and clothing when returning from trips.
• Use protective mattress encasements.
• Rely on professional heat treatments or thorough chemical applications for persistent infestations.
