Few homeowners are unfamiliar with the antics of squirrels. Squirrels have a penchant for wreaking havoc in and around your yard, and sometimes inside your home or outbuildings. They are well known for tearing apart attic insulation, and they can even cause fires by chewing on electrical wiring. Another annoying activity that squirrels engage in is chewing on propane gas grill hoses. Not only will this cost you money, it can also be extremely dangerous. Preventing squirrels from tearing up your propane hose can be as simple as replacing it with a material they can't chew through.
Clean your gas grill. Squirrels are attracted to grease or scraps on the patio or ground around a grill. Once they are near your grill, they may go after the propane hose. Wipe down your grill with a degreasing liquid or foam and a sponge, making sure to wipe the propane hose with the degreaser as well. Empty the grease trap from the grill if it has one. Remove stuck-on food and grime from the grill grates.
Replace the hose connected to your propane tank with a stainless steel hose. Squirrels cannot chew through stainless steel hoses, and they are unlikely to keep trying once they realize the change. Purchase a stainless steel hose for gas grills at a home improvement supply store, or through an online retailer. Take the old hose with you to the store, or measure the length so you purchase the correct size for your grill. Propane hose fittings are normally universal in diameter, but it is a good idea to measure yours before purchasing a new one.
Trap the squirrels. First check your local laws to make sure trapping is legal in your area. Set a live trap or two around the grill. Bait the traps with nuts, sunflower seeds or peanut butter, and leave them alone for a few hours. Check the traps for squirrels at least every morning and evening. Call your local animal control department for advice on using live traps and relocating the squirrels. In many areas you cannot simply release squirrels wherever you choose. Your animal control department may also have a trap lending program so you don't need to buy your own.
