Snakes on the Bolivar Peninsula, Texas: Species and Safety
There are snakes on the Bolivar Peninsula, including venomous cottonmouths near marshes and the occasional rattlesnake. Most snakes you'll encounter are harmless. Here's what to watch for and how to stay safe.
Snakes on the Peninsula
The Bolivar Peninsula has snakes. That's true of every rural and semi-rural area in Texas. Most of the snakes you might encounter are nonvenomous species: rat snakes, garter snakes, Gulf coast ribbon snakes, and coachwhips. These are harmless and actually helpful since they eat rodents and insects.
But there are two venomous species to be aware of. Cottonmouths (water moccasins) live near the marshes, ponds, and ditches. Western diamondback rattlesnakes are rare on the peninsula but they've been spotted in grassy and undeveloped areas. Knowing these exist is the first step toward staying safe.
Cottonmouths (Water Moccasins)
Cottonmouths are the most common venomous snake on the Bolivar Peninsula. They live near freshwater: marshes, retention ponds, drainage ditches, and wet grassy areas. They're thick-bodied snakes, usually dark brown or black, with a triangular head. When threatened, they open their mouth wide to display the white interior. That's where the name comes from.
Cottonmouths are not aggressive, despite their reputation. They hold their ground rather than flee, which makes people think they're attacking. If you see one, back away slowly. They don't chase people. That's a myth. Give them space and they'll leave you alone.
Rattlesnakes
Rattlesnakes are uncommon on the Bolivar Peninsula but not impossible. Western diamondback rattlesnakes have been found in grassy, undeveloped areas and near dunes. They're more common further inland in Texas. If you hear a rattle, stop, locate the snake, and back away.
Rattlesnakes are most active in warm months and tend to rest during the heat of the day. Dawn, dusk, and nighttime are when you're most likely to encounter one. They're not looking for trouble. The rattle is a warning that says back off.
How to Stay Safe
Watch where you step, especially at night. Use a flashlight when walking around your property or on paths after dark. Snakes are most active at night during summer months. Stick to well-lit, clear paths.
Wear closed-toe shoes when walking in grass, near marshes, or in undeveloped areas. Flip-flops are fine on the beach but not in the scrub. Keep yard areas around your rental clear of debris, wood piles, and tall grass since snakes like to hide in cover.
If you're bitten by a venomous snake, get to a hospital. Don't try home remedies. Don't cut the wound. Don't apply a tourniquet. Don't suck out the venom. Just get to the ER. The nearest hospital is in Galveston. Call 911 if the situation is serious.
