The Top Bugs in Texas That Bite Humans

Texas is home to a wide variety of bugs that can bite and sting humans. While most bug bites are harmless, some can cause reactions ranging from mild itching to severe allergic responses. Knowing how to identify and avoid these biting bugs is key to staying safe in the Lone Star State.

Mosquitoes

Mosquitoes are by far the most common biting bugs in Texas. There are over 85 species found across the state, with the southern house mosquito and the Asian tiger mosquito being the most widespread. Mosquito activity peaks from May to October, especially around dawn and dusk.

While itchy mosquito bites are annoying, the bigger concern is mosquito-borne diseases like West Nile virus, Zika, and Chikungunya. Use EPA-registered insect repellents containing DEET, picaridin, or oil of lemon eucalyptus when spending time outdoors. Also drain standing water around your home to reduce mosquito breeding habitat.

Chiggers

Chiggers are tiny, red mites that are most active from June to September. They inhabit grassy and weedy areas and can latch onto exposed skin. The chigger bites itself is painless, but it injects digestive enzymes that cause severe itching and dermatitis.

To prevent chigger bites, wear long pants and sleeves when in grassy fields or overgrown lawns. Tuck pant legs into socks and apply permethrin to clothes and shoes. Check your body closely after exposure and wash with soap and water. Oral antihistamines can help relieve itching.

Fleas

Cat fleas, dog fleas, and human fleas are all found in Texas Fleas thrive in warm climates and live in carpet, bedding, grass, and animal fur Their bites look like small red dots, usually around ankles and legs. Intense scratching can cause infection.

Flea control starts with treating pets with vet-approved medications. Keep grass mowed and remove debris that harbors fleas. Use flea medicine and flea collars on outdoor pets. Vacuum and wash bedding frequently in hot, soapy water.

Ticks

Texas has many tick species like Lone Star ticks Gulf Coast ticks brown dog ticks, and deer ticks. Ticks reside in shrubs and tall grass waiting to grasp onto a human or animal host. Tick bites often go unnoticed, allowing them to feed for days and spread diseases.

Perform tick checks after being outdoors, especially in wooded areas. Remove attached ticks promptly with tweezers. Applying permethrin can help repel ticks from clothing. Control ticks in your yard by removing brush and keeping grass short.

Bed Bugs

While not insects, bed bugs are a growing problem in Texas They hide in cracks and crevices in beds, furniture, and luggage Their bites resemble mosquito bites and occur most often on exposed skin at night. Scratching bites can lead to infection.

Inspect for signs of bed bugs when traveling and avoid bringing used furniture into your home. Use encasements on mattresses and box springs. Remove clutter around beds and treat infestations promptly with insecticides or heat treatment. Monitor closely and repeat treatments to kill hatching bugs.

Fire Ants

Fire ants are aggressive, stinging insects found across Texas. There are four major species including red and black imported fire ants. Fire ants build mounds in open areas like lawns, parks, and pastures. They will viciously defend their colony if disturbed.

Fire ant stings cause burning pain and itchy pustules on the skin. Those allergic can experience severe reactions needing emergency care. Prevent fire ant stings by wearing closed toe shoes outdoors, treating mounds with bait, and keeping grassy areas trimmed short.

Wasps, Hornets & Bees

Stinging insects like yellowjackets, paper wasps, hornets, and honey bees are common statewide. They build nests on trees, in the ground, or in wall voids of homes. Stings typically occur when the insects feel threatened by swatting or accidental contact.

Look for nests around the home and avoid disturbing them. Keep food and drinks covered when eating outdoors. Remain calm and move away if stung to avoid further stings. Use ice packs and OTC meds to ease swelling and pain. Seek emergency care for allergic reactions.

Scorpions

Texas has over 20 scorpion species, including striped bark scorpions, giant desert hairy scorpions, and Texas cave scorpions. Scorpions inhabit dark, dry spaces like attics, crawlspaces, woodpiles, and underneath debris. Stings are painful but rarely life threatening.

Seal cracks around the home’s exterior to deter scorpions. Inspect shoes and clothing before use. Use glue boards or blacklights to monitor for scorpions indoors. Seek medical attention for numbness, frothing, and difficulty breathing from a sting. Consult a pest professional for severe infestations.

Spiders

Venomous spiders like black widows, brown recluses, and brown widow spiders reside throughout Texas. They inhabit garages, sheds, wood piles, and undisturbed areas in homes. Bites can cause mild to serious reactions depending on the species.

Inspect boxes and clutter before grabbing to avoid surprise bites. Shake out shoes and clothing stored in garages and sheds. Manage insects around the home to avoid attracting spiders. Get medical help if bite reactions seem serious or persist beyond 48 hours.

By familiarizing yourself with the most common biting and stinging bugs in Texas, you can take appropriate precautions when spending time outdoors. Always have first aid supplies on hand and seek medical attention if bite reactions seem severe or don’t improve within a few days. Protect yourself and enjoy the natural beauty of the Lone Star State!
