The most effective termite treatments are liquid termiticides, bait termiticides, heat treatment, and fumigation. Which one is best for your situation will depend on a number of factors, including: • Where the termites are located  • The extent of the infestation  • Whether you want to use chemicals • Type of termite Pre- and post-construction liquid chemical treatments are also effective at eliminating termites on a home site. Heat treatment is an effective non-chemical solution that is popular and convenient for many homeowners. Other non-chemical treatments involve a physical barrier such as steel mesh or sand.  Biological control agents, such as nematodes and fungi, are another chemical-free option. However, biological control agents have mainly had success in a laboratory setting and are not EPA regulated. If there is a termite infestation, it’s best to call an exterminator to help you determine the most effective termite treatment for your situation.
