How to Confirm It's a Rat Snake
Three signs tell you it is a rat snake and not something more concerning:
| Sign | Rat Snake | Not a Rat Snake |
|---|---|---|
| Sound | Scratching, slithering, occasional thump — mostly at dawn and dusk. Sounds like something heavy being dragged. | Raccoons: loud thumping, vocalizations. Squirrels: rapid scurrying, gnawing, daytime activity. Mice: light scratching, constant, high-pitched. |
| Time of Activity | Dawn and dusk (crepuscular). You will hear it most around 5-7 AM and 6-8 PM. | Nocturnal-only sounds = flying squirrels or rats. Daytime-only = gray squirrels. |
| Evidence | Shed snake skin (3-6 feet long, papery white, found in attic or near entry point). No droppings that look like rodent droppings — snakes leave a white chalky urate with dark feces. | Rodent droppings (small, dark pellets). Chewed wires, shredded insulation for nesting. |
Is It Dangerous? What to Do If You Find One
Texas rat snakes are completely non-venomous and not aggressive toward humans. They will bite if cornered or handled, but their bite is superficial — like a cat scratch, not medically significant. Clean with soap and water. The snake is far more scared of you than you are of it.
If you actually see the snake: do not scream, do not swing at it, do not try to grab it. A cornered rat snake will coil, vibrate its tail (mimicking a rattlesnake as a bluff), and strike defensively. Back away slowly. It will retreat to the nearest dark space. The snake wants to avoid you as much as you want to avoid it.

How to Safely Remove a Rat Snake
You have three options, from most to least recommended:
- Do nothing (recommended). A rat snake in your attic means you have rodents. The snake is solving a problem you should be grateful it found. Remove the rodents (see Prevention below), seal the entry point, and the snake will leave within 2-3 days when its food source disappears.
- Encourage it to leave. Place a bright light and a portable radio (talk station, not music) in the attic for 48 hours. Snakes prefer dark, quiet spaces. The disturbance will encourage it to move on without harming it.
- Professional removal. If the snake is in a living area (not the attic) or you cannot wait, call a licensed wildlife removal professional. In Texas, native snakes cannot be relocated more than 100 yards from where they were found without a TPWD permit. A professional will know the regulations.

How to Rat-Proof Your Attic
The snake is not the problem. The rodents are. Fix the rodents, and the snake never comes back. Here is how:
- Seal every opening larger than a dime. A rat can squeeze through a hole the size of a quarter. Use 1/4-inch hardware cloth (not chicken wire — rats chew through it) and expanding foam for gaps. Check: roof vents, soffit gaps, pipe penetrations, chimney flashing, and where the roof meets the siding.
- Trim tree branches. Rat snakes climb trees and enter through overhanging branches touching the roof. Trim all branches to at least 6 feet from the roofline.
- Remove exterior food sources. Bird feeders, pet food, unsealed garbage, compost piles — all attract rodents, which attract snakes.
- Check your attic insulation. If you see trails, tunnels, or nests in the insulation, you had rodents before the snake arrived. The snake is the cleanup crew.
