Fire ants are a common threat in Texas, delivering painful stings that can cause severe allergic reactions in some individuals. These ants build large mounds and aggressively defend their territory.
Kissing bugs, found in rural areas, can transmit Chagas disease. These nocturnal insects often bite around the mouth or eyes while people sleep. Chagas disease can lead to serious heart and digestive problems if left untreated.
Mosquitoes in Texas can carry West Nile virus and other diseases. They breed in standing water and are most active during dawn and dusk. Using insect repellent and eliminating standing water sources helps reduce mosquito populations.
Spider Bites and Venom Toxicity
Brown recluse spiders are known for their venomous bite. These spiders prefer dark, secluded areas and are often found in closets, attics, and woodpiles. Their bites can cause necrotic lesions and systemic symptoms in some cases.
Black widow spiders are another venomous species in Texas. Females are easily identified by their shiny black bodies and red hourglass marking. Their bites can cause severe pain, muscle rigidity, and nausea.
To avoid spider bites, wear gloves when handling stored items or working outdoors. Shake out shoes and clothing before use, especially if left unused for extended periods.
Risks from Other Wildlife Interactions
Deer in Texas can pose indirect health risks by serving as hosts for ticks carrying Lyme disease. Avoid areas with high deer populations and check for ticks after outdoor activities.
Armadillos can carry leprosy bacteria. While transmission to humans is rare, it’s best to avoid direct contact with these animals. Wear gloves if handling armadillos is necessary.
Raccoons and skunks may carry rabies. Never approach or attempt to handle these animals, even if they appear friendly or injured. Teach children to admire wildlife from a safe distance.
Keep food waste securely contained to avoid attracting wildlife to residential areas. This reduces the risk of potentially dangerous encounters.
Aquatic Dangers in Texas’ Waters
Texas waters harbor several potentially dangerous aquatic species. Visitors and residents should be aware of the risks posed by sharks in coastal areas and alligators and venomous snakes in freshwater habitats.
Sharks: Understanding the Risk in the Gulf
Shark encounters in Texas coastal waters are rare but possible. Bull sharks are the most common potentially dangerous species, known to venture into freshwater rivers and bays. Great white sharks occasionally visit Gulf waters but are less frequently seen near shore.
Shark attacks on humans in Texas are infrequent. From 1911 to 2022, only 43 unprovoked shark attacks were recorded in the state. Most incidents involve minor bites rather than fatal attacks.
To minimize risk:
- Avoid swimming at dawn, dusk, or night when sharks are most active
- Stay in groups and avoid areas with fishing activity
- Don’t enter the water if bleeding
Freshwater Threats: Alligators and Venomous Snakes
American alligators inhabit Texas’ wetlands, swamps, and rivers. While typically wary of humans, they can be dangerous if provoked or protecting nests. Alligator attacks are rare but can be severe.
Venomous water snakes pose another risk in freshwater habitats. Cottonmouths (water moccasins) are common in aquatic environments across much of Texas. Timber rattlesnakes may also be encountered near water sources.
Safety tips:
- Keep a safe distance from alligators (at least 30 feet)
