How to Keep Insects Out of My Gas BBQ Grill Burners

Scrape the grill grates with the wire grill brush to remove food particles that may be attracting insects to a free meal.

Fire up the gas grill as you normally would, adjusting the burners to the highest setting. Close the cover and let the grill heat for 10 minutes before shutting off the appliance. This will kill anything alive inside the grill and burn off excess grease that lures bugs.

Sweep out the debris in the bottom of the grill with a whisk broom and dustpan, moving the lava rocks or ceramic briquettes to one side so you can access the inside bottom.

Spray the underside and back of the grill with a light mist of insecticide, which will keep insects off the appliance for at least a week. Reapply spray every 10 days.

Pull the burner pipes out of the venturi tubes on the underside of the grill, behind the control panel. The pipes are not physically connected to the tubes, so you can simply pull them out.

Swab each venturi tube with a pipe cleaner to remove spider webs and nest material that can accumulate inside. Reinsert the burner pipes into the tubes when finished.

Wrap the venturi tubes with plastic bags and secure with rubber bands if the grill will not be in use for more than a month, such as during the winter.

Place a grill cover over the gas grill and secure the drawstrings at the bottom to discourage flying insects from making a home in your barbecue.
