It's generally recommended to have a termite inspection at least once a year, especially in areas prone to termite activity. Regular inspections can help catch any infestations early and protect your property. If you live in a high-risk zone, you might consider more frequent checks. Additionally, if you notice any signs of termites, such as mud tubes or damaged wood, contact a licensed pest control professional immediately. For detailed advice, you can also check resources on pest management from your state’s government website.
