Use an orange oil spray to kill termites around the home. Orange oil dissolves the exoskeleton of termites, which destroys their membranes and causes them to die of severe water and protein loss.
- Buy orange oil
Purchase orange oil online or at a local store. If you cannot find orange oil spray, buy a regular bottle of orange oil, and pour the contents into an empty spray bottle. Be careful when pouring the oil, as it can irritate your skin and eyes.
- Locate the termites
Walk the perimeter of your home, and search for the source of the termites. Look for tunnels in the foundation, sawdust around deck railings, and small bugs that resemble ants.
- Treat the infestation
Spray the orange oil on the wood, in holes and directly on the termites. If you have a subterranean termite infestation, inject the orange oil into the burrows to eliminate the termites at the source.
- Retreat the area
Allow up to three days for the orange oil to take effect fully. Depending on the severity of the infestation, it can take up to three weeks to kill the termites. Retreat the infested area to ensure you kill any adult termites or larvae that survived the first round of treatment.
