Patent attributes
A method includes a burning step, a cleaning step, a drugging step, a covering step, and a sealing step to effectively exterminate insect pests inside and outside an ant mound. Specifically, the ant mound is intermittently burnt with flame to kill the insect pests that run out of the ant mound in batches. The ant mound is then removed to expose outlets of ant channels. Next, pharmaceuticals are placed in and surround the outlets of the ant channels. A container is then placed on top of and covers the outlets of the ant channels. The container is sealed to isolate the interior of the container from the exterior of the container, avoiding leakage of gasified pharmaceuticals and preventing entrance of ambient fresh air into the container. Sunlight transmitting the container gasifies the pharmaceuticals in the container, and gasified pharmaceuticals flow into deep channels to kill the insect pests.
