How to make termites go away naturally?

Making termites go away naturally is difficult for large infestations because natural remedies rarely eliminate entire colonies with millions of members, but several natural and preventative methods can help reduce risk and supplement professional treatment for minor issues. The most effective natural approach is moisture control, because subterranean termites need high humidity and moisture to survive, so fixing leaky pipes, ensuring gutters drain away from foundation, ventilating crawl spaces, and removing wood-to-soil contact makes environments inhospitable. Removing food sources including firewood stacked away from house, wood debris, cardboard, and mulch near foundation reduces attraction. Direct natural treatments include beneficial nematodes, which are microscopic parasitic worms that infect and kill termites from inside and can be purchased online and applied to soil around foundation, though effectiveness varies. Orange oil containing d-limonene extracted from orange peels can kill drywood termites on direct contact when injected into infested wood galleries but has limited penetration and does not reach entire colonies. Boric acid powder or borax mixed with water and applied to wood can kill termites that ingest treated wood but is slow acting. Diatomaceous earth, a natural powder made from fossilized algae, can dehydrate termites when dusted in dry areas but must stay dry. Vinegar and sunlight exposure can kill some surface termites but not colonies. For natural prevention, use pressure-treated wood, cedar or redwood which are somewhat resistant, and maintain barriers. For active structural infestations, natural methods alone are insufficient and professional liquid barriers or bait systems costing $1,000 to $3,000 are needed for complete elimination.
