Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

A metal hollowed probe having a couple of orifices near the bottom is mechanically or manually inserted into the fire ant mound. Heated gas in the metal hollowed probe is ejected in pulse from the orifices into the ant mound, going through channels in the mound, whereby the whole ant mound is filled with the heated gas rapidly. Fire ants and ant queens are killed by the heat before they move to safety. The invented device provides a fast and safe method for killing fire ants and ant queens without using any hazardous or toxic poisons.
