Local or spot control methods include the use of pesticides,   also includes the removal and replacement of infested structural timber. These methods are intended to remove or kill termites only within the specific targeted area, leaving open the possibility of other undetected infestations within the structure. These treatments are NOT designed for whole-house eradication.   Local or spot treatment with pesticides involves drilling and injecting pesticides into infested timbers as well as the topical application of toxic chemicals.
