Method of treating an insect infestation of a tree

A method of treating an insect infestation of a tree, comprising:

• drilling a first hole and a second hole into the tree;
• inserting a microwave emitter probe of a pest control device into the first hole;
• placing a temperature monitor probe of the pest control device into the second hole;
• emitting microwave radiation from the microwave emitter probe to increase a temperature in the tree;
• and wherein the pest control device comprises:
• an electronic controller, wherein the electronic controller is cuboidal, has a top side, a bottom side, a front side, a back side, a left side, and a right side;
• a microwave generator disposed in the electronic controller, wherein the microwave generator is connected to the microwave emitter probe via a coaxial cable, wherein the microwave emitter probe is connected at the top side of the electronic controller, wherein the microwave emitter probe is cylindrical with a microwave emitter probe length of 5 to 50 cm and a microwave emitter probe diameter of 0.25 to 5 cm;
• the temperature monitor probe is connected to the left side of the electronic controller via a flexible cable, wherein the temperature monitor probe is cylindrical with a temperature monitor probe length of 1 to 25 cm and a temperature monitor probe diameter of 0.5 to 5 cm, wherein the temperature monitor probe comprises an infrared sensor to detect the temperature inside the tree;
• a temperature monitoring system disposed at the front side of the electronic controller, wherein the temperature monitoring system comprises a feedback circuit to display a thermogram and to adjust a microwave frequency, an alert system with a temperature threshold limit, and an user interface panel, wherein the user interface panel displays the temperature, the microwave frequency, and a microwave operation time;
• at least one or more cooling fans disposed at an apex of the left and right sides of the electronic controller;
• a control unit positioned below the user interface panel at the front of the electronic controller, wherein the control unit comprises a microwave intensity button, a power supply button, and a microwave operation time button.
