Abstract: An apparatus for probing rodent burrows and dispensing a measured amount of rodent bait into the burrow. The disclosed apparatus comprises an elongated four-sided hollow shaft with a bait tank sealingly connected to the hollow shaft. The hollow shaft has a shaft tip which is also four-sided. One side of the shaft tip, the sealing end, slides with respect to the other three sides to open or close the shaft tip. The sealing end is at one end of a pusher bar. The other end of the pusher bar is connected to a thumb plate, so the operator may open or close the shaft tip using the thumb plate. A measure dose of bait is placed at the probe tip for dispensing by raising and lowering the probe tip, which causes bait to flow through either a calibrated orifice or a divider within the bait tank and enter into the four-sided hollow shaft.
