There’s nothing better than firing up the grill and indulging in some delicious barbecued goodness. But imagine the frustration of discovering that your propane gas line to your grill has been chewed up by critters, leaving you unable to cook your favorite meals.
Squirrels and other animals have a natural instinct to chew on objects, and unfortunately, propane hoses, to both your grill and your home, are not immune to their curiosity.
Why do critters chew on propane gas lines?
Teeth Maintenance: Like all rodents, squirrels have constantly growing teeth. Chewing on hard objects, such as propane hoses, helps to keep their teeth from becoming too long and causing health issues.
Curiosity: Many small animals are naturally curious creatures, exploring their environment by nibbling on various objects they encounter, including propane hoses.
Scent Attraction: The smell of propane can be enticing to some animals, especially when the hose has absorbed cooking or grilling odors.
Nesting Material: In some cases, rodents may chew on propane hoses to use the pieces as nesting material, especially during nesting seasons.
How to protect your propane gas line from these relentless chewers.
Cover the Gas Line
One of the most effective ways to safeguard the gas line itself is to cover it with a durable material that critters cannot chew through. Some options include:
- Steel Mesh: Wrap the gas line with a tightly woven steel mesh, such as hardware cloth or chicken wire. This material is too tough for critters to gnaw through, acting as an excellent deterrent.
- PVC Pipe: Slide the gas line through a larger PVC pipe, preferably a pipe with a diameter too big for small animals to fit their jaws around.
- Corrugated Conduit: Consider using a corrugated conduit, typically used to protect electrical wires, to shield your propane hose. The ridges and material make it difficult for vermin to chew.
Apply Repellents
There are various natural and commercial repellents that can help keep squirrels and the like away from your gas line:
- Homemade Pepper Spray: Create a homemade animal repellent by mixing water with cayenne pepper or hot sauce. Spray this solution on and around the gas line periodically. The spicy scent will deter them from approaching the area.
- Commercial Repellents: Look for animal repellent sprays specifically designed to deter them from gnawing on hoses and wires. These repellents are usually safe for use around humans and won’t harm the creatures either.
Utilize Ultrasonic Devices
Ultrasonic devices emit high-frequency sounds that are unpleasant to animals but inaudible to humans. They can be placed in the ground and powered by solar energy, or even screwed into the side of your house and plugged into an outdoor outlet.
Place these devices near the gas line to create an uncomfortable environment for critters.
Store Propane Tanks and Hoses Properly
If possible, keep the propane tank and hoses for your grill in a shed or garage when not in use. Disconnect the hoses and store them separately.
Ensure the area is secure and inaccessible to animals by using sturdy containers or elevated shelves. This will significantly reduce the chances of critters getting to your propane tank and hoses in the first place.
Regular Maintenance and Inspection
Regularly inspect the gas line and the surrounding area for signs of chewing or damage, and trim nearby vegetation and trees to eliminate potential pathways for the rodents to access the gas line.
Make sure to check both the small line for your grill and the larger one for your home. Chances are that if squirrels or other animals got to one, the other is in imminent danger.
Don’t hook up your propane tank to your home line
If you have a small gas line for your grill running from your main line, you’ve left your home and wallet vulnerable. We recommend leaving them separate to avoid higher leak risks, which can mean a very expensive fix.
Promptly address any issues you find to prevent further damage.
Bid Farewell to Delayed Grilling Adventures
With a combination of proper storage, covering the gas line, applying repellents, and regular maintenance, you can bid farewell to chewed-up propane hoses and relish uninterrupted grilling adventures.
But beyond implementing preventive measures, there’s an added layer of security in choosing a reliable gas company for routine inspections and ensuring a steady supply of propane.

FAQ
Why do animals chew on propane gas lines?
Rodents like squirrels chew on propane hoses for a few reasons: to maintain their constantly growing teeth, out of curiosity, or because they’re attracted to food smells or propane scent residue. Some even collect hose material for nesting.
What’s the most effective way to prevent chewing on propane hoses?
The best approach is to block access physically. Wrapping the hose in steel mesh, sliding it through a PVC pipe, or using a corrugated conduit makes it difficult for animals to bite through. Combining physical barriers with repellents gives you even better protection.
Do animal repellents actually work on propane lines?
Yes, both homemade and commercial repellents can help. A cayenne pepper spray or a specialized commercial product can deter animals without harming them. Just be sure to reapply regularly, especially after rain or heavy use.
Is it safe to leave propane hoses connected when not in use?
No, it’s better to disconnect and store your propane hose and tank in a secure place when not in use. Sheds, garages, or sealed containers can protect your setup and greatly reduce the chance of rodent damage or gas leaks.
