Walk through any hardware store and you will find shelves of snake repellent products promising to keep slithering intruders away. But do these products actually work? And what about professional snake away services? This guide separates fact from fiction and explains what genuinely keeps snakes off your property.

1Common Snakes in Our Service Area
Understanding which snakes you might encounter helps inform prevention strategies:
Venomous Species
These snakes pose genuine health risks and require professional removal:
- Copperheads—most common venomous snake in our region
- Western Diamondback Rattlesnake—found in TX and OK
- Cottonmouth (Water Moccasin)—near water sources in all states
- Coral Snake—rare but dangerous, found in southern TX and LA
Non-Venomous Species
These snakes are beneficial and generally harmless:
- Rat snakes—excellent rodent control
- Garter snakes—common garden visitors
- Coachwhip—fast-moving and shy
- Texas Indigo—actually eats rattlesnakes
2Do Snake Repellent Products Work?
The short answer is: most do not work as advertised. Here is what research shows:
Naphthalene and Sulfur Products
These are the most common active ingredients in store-bought repellents:
- University studies show minimal to no effectiveness
- Snakes will cross treated areas when motivated
- Naphthalene (mothballs) is toxic to pets and children
- Sulfur washes away quickly in rain
Essential Oil Products
Products containing cinnamon, clove, or cedar oil:
- No scientific evidence supporting effectiveness
- May provide brief deterrent effect at best
- Require constant reapplication
- Marketing often exceeds actual performance
Ultrasonic Devices
Electronic devices claiming to repel snakes:
- Snakes do not hear airborne sounds the way mammals do
- They sense ground vibrations instead
- No scientific support for ultrasonic repellent claims
- Save your money for proven methods
3What Actually Keeps Snakes Away
Effective snake prevention focuses on habitat modification, not repellents:
- Remove food sources—snakes follow prey (rodents, insects, frogs)
- Eliminate hiding spots—brush piles, tall grass, debris
- Seal entry points—gaps under doors, foundation cracks
- Reduce moisture—fix irrigation leaks, improve drainage
- Keep landscaping tidy—trim shrubs, store firewood away from house
4Professional Snake Services: What to Expect
Legitimate snake control services focus on exclusion and habitat modification:
Property Inspection
A thorough inspection identifies why snakes are attracted to your property:
- Identifying snake species present or likely
- Locating entry points into structures
- Assessing food sources (rodent populations)
- Evaluating habitat conditions
Exclusion Work
Physical barriers are the most effective snake deterrent:
- Sealing gaps under doors with door sweeps
- Installing hardware cloth over vents and weep holes
- Filling foundation cracks and gaps
- Snake-proof fencing for high-risk areas
Habitat Modification
Making your property less attractive to snakes:
- Recommendations for landscaping changes
- Addressing rodent populations that attract snakes
- Reducing moisture and shelter opportunities
5When to Call a Professional
Professional help is warranted in these situations:
- You have seen a venomous snake on your property
- Snakes are entering your home or garage
- You have repeated snake encounters despite efforts
- You need a snake removed and cannot identify the species
- You want a professional property assessment
6DIY Prevention That Works
Homeowners can take effective steps without special products:
- Mow lawn regularly and keep grass short near the house
- Remove brush piles, rock piles, and debris
- Store firewood at least 20 feet from your home
- Trim shrubs and bushes so you can see under them
- Address rodent problems to remove the food source
- Install tight-fitting door sweeps on all exterior doors
- Cover vents and weep holes with hardware cloth
7The Bottom Line on Snake Repellents
After decades of testing, the consensus is clear:
- No chemical repellent reliably keeps snakes away
- Habitat modification is the only proven approach
- Exclusion prevents snakes from entering structures
- Removing food sources (rodents) reduces snake attraction
- Be skeptical of products promising easy snake solutions
