An ant blockading apparatus includes: an electric shock circuit board secured on a supporting column standing on a base member laid on a surface, and a platform mounted on an upper portion of the supporting column and positioned above the electric shock circuit board for placing a container of food or the like on the platform; the electric shock circuit board having a plurality of positive electrodes concentrically or parallelly formed on a bottom of the circuit board and electrically connected to a positive pole of a power source, and a plurality of negative electrodes concentrically or parallelly formed on the bottom of the circuit board and electrically connected to a negative pole of the power source, each positive electrode juxtapositional to each negative electrode having an electrically insulative medium sandwiched in between the positive and negative electrodes, whereby upon creeping of an ant over the positive and negative electrodes to shortcircuit the electrodes and the power source, an electric shock will be applied to the ant to cause its falling down or to repel it for preventing ant invasion into the container above the electric shock circuit board.

A non-toxic, non-chemical, non-polluting, inexpensive electronic apparatus (10) which controls the fly population within an animal or poultry enclosure which kills by destroying the nervous system of the fly with a short pulse of a high voltage that is applied to a pair of conductors (80) and (81) every 1 to 5 seconds.

An electric or electronic animal trap wherein the housing includes a pair of spaced electrodes or charge plates in a killing chamber intermediate the trap entrance and a source of bait. Interposed in the pathway to the electrodes is at least one diverter which discourages a target animal from reversing direction before it is electrocuted. In one embodiment, juxtaposed to the entrance are at least two diverter members angularly offset relative to each other to define a maze-like path to lead a target animal to the charge plates for electrocution while discouraging reversal of direction and protecting against direct access to the charge plates through the entrance opening by children, pets or non-target species. A diverter or barrier plate may be carried by the housing cover to extend into the space between the electrodes when the cover is closed, the lower edge of the barrier being spaced from the housing floor a limited distance to force a target animal to squeeze under the barrier as it passes to the second electrode making escape before electrocution difficult. This design may be utilized in combination with a spaced, upwardly extending diverter or barrier plate to block direct access to the pair of electrodes from the entrance opening. The effectiveness of an inclined plane trap assembly may also be enhanced by a plate carried by the cover which forces a target animal to stretch itself out before engaging the second electrode.

Method and apparatus for controlling fire ants. A method is disclosed for controlling colonies of fire ants in the environment. The method includes first providing a stimulating source that, when activated, will attract fire ants to contact the stimulating source and become agitated to a point that ants from a common colony will attack each other. Thereafter, the stimulating source is activated to cause the fire ants to cluster around the stimulating source, become agitated, and attack each other. The stimulated fire ants then are urged into a tightly confined space to exacerbate the attack reaction.
