Bucket Calibration


Bait spreaders intended for use during the eradication of rats from Rat Island in the Aleutian Islands during October 2008 were tested and calibrated in August. The purpose of the calibration was to adjust the application rate for a known altitude and flying speed of the helicopter.

Non-toxic Bait

Only non-toxic (placebo) biodegradable bait pellets were used during the calibration. The pellets were the same size and weight as the bait planned to be used on Rat Island.


A helicopter and bait spreader (bucket) are used to broadcast bait pellets across an area at a precise application rate.
