- 1). Try baiting. Baits target subterranean and Formosan termites, and this method is desirable because there are no poisons involved and no drilling is needed. This process, however, could take months to work, giving the termites more time to do more damage.
- 2). Check on using borates. Borates target subterranean and Formosan termites and they provide permanent protection. Professionals spray bare wood with boron and fill cavities in walls with a foam containing boron. Borates are not toxic to humans, but it can be difficult to reach uncovered wood in homes. This method could take weeks to work.
- 3). Try spot injections. This type of method targets all types of termites. Professionals drill into walls and inject pesticides where termites nest and feed. This method works quickly, but only works in the areas where it is applied. It may also take another application at a later date, according to an article published on This Old House.
- 4). Consider fumigating your home. This kills dry wood and some wood-boring termites. With fumigation, professionals fill the entire house with poison gas. This method is usually very effective and leaves behind little residue or odor.
