A non-toxic fire ant extermination system providing probe injection of scalding water below ground level within a fire ant mound is disclosed. The system includes a propane fueled water heater and water circulating pump capable of heating water in the range of 200 to 210 degrees Fahrenheit and of delivering the same at a flow rate of least three gallons per minute which is effective to eradicate the insects within the core region of a fire ant mound. The injection probe features a cylindrical capture shield which is radially disposed about the probe and adapted for sliding attachment therewith being spring-biased in a downward direction against the surface of the ground during operation thereof to retain the intense heat generated by the process,to capture fire ants emerging from the mound, and to protect the operator from the backflow of scalding water as the treatment proceeds. The injection probe is inserted below ground level and a continuous flow of scalding water is introduced into the mound as the probe is inserted further and slowly withdrawn until the hot water has penetrated throughout the core region of the mound complex. The fire ant extermination system is adaptable for use with any natural source of fresh water by use of a suitable filter system. In the alternative the system is adaptable to any municipal water supply having adequate water pressure in the range of 40 to 60 pounds per square inch.

[ What is claimed is:] [1.] A fire ant extermination system for probe injection of scalding water into a core region is the lower depths of a fire ant mound, said system comprising:means for heating water to a temperature of approximately 200 degrees to 210 degrees Fahrenheit;means for pressurizing the water in said means for heating, water to a pressure of approximately 40 to 60 pounds per square inch,injection probe means including an elongated tubular member, a conical probe having radially disposed apertures formed therein connected at one end of said tubular member and a high pressure hose connected at the other end of said tubular member to said means for pressurizing the water by a predetermined length of high pressure hose means, said tubular member having sufficient length for said conical probe to penetrate to said lower depths of said fire ant mound;a generally cylindrical capture shield means having a height and a bottom surface radially disposed about and longitudinally slideable on said tubular member for movement between a first position adjacent said conical probe and a second position adjacent said other end of said tubular member; andspring means surrounding said tubular member for mechanically biasing said capture shield toward said conical probe and accommodating movement of said shield along said tubular member toward said second position as said injection probe, means extends beyond the bottom surface of the capture shield means by a distance at least equal to the height of the capture shield means and is inserted into the core region at the lower depths of said fire ant mound, whereby scalding water and ants are prevented from escaping during the extermination process.
