PROBLEM TO BE SOLVED: To precisely and efficiently practice spraying of a chemical on an object of a termite-proofing treatment over a plurality of times. SOLUTION: Each perforated cylindrical body 200 having communicating holes 202 communicating with soil 20 and an inner cavity 201 is installed in the soil 20 just under a foundation 100 or around the foundation 100 of a building 10 to be the object of the termite-proofing treatment. Each inserting tool 300 having jetting ports 301 for jetting the termite-proofing chemical and a flexible tube 302 for feeding the termite-proofing chemical forcedly fed under pressure with a forced feeder 350 to the jetting port 301 is inserted so that the jetting ports 301 are located in a passage position corresponding to a region of the termite-proofing treatment in the inner cavity 201 in the perforated cylindrical body 200. The termite-proofing chemical is fed from the forced feeder to the inserting tool 300 inserted into the inner cavity 201 to jet the termite-proofing chemical from the jetting ports 301. The termite-proofing chemical jetted from the jetting ports 301 is permeated through the communicating holes 202 of the perforated cylindrical body 200 into the soil 20. COPYRIGHT: (C)2005,JPO&NCIPI
