    Abstract: The disclosure relates to a device for killing ants and other insects by electrocution. The device includes an elongated shaft or probe for insertion into the anthill and an adapter for connecting the device to an electrical source. A charge ring is spaced from a charge plate between which ants can pass. When ants attack the device having been inserted into the anthill, those that find themselves between the charge plate and the charge ring will short circuit the device causing the ants to be electrocuted.
