Red Squill Informational Documents --
Scope and Contents

The files were located in a folder labeled “Appendum: Red Squill Briefing Data (Data not sent to Washington August 12, 1974), so they were likely part of a larger collection of informational material and data.

Biographical / Historical
Red squill is a rodenticide derived from the bulbs of a lily-like plant, Urginea maritima, that is native to Mediterranean regions. The bulb extracts and dried powders have a long history of use as a rodenticide. As early as the 1920s, red squill was studied and used by the USDA for rodent control. In the face of rodenticide shortages during World War II, the Denver Wildlife Research Laboratory developed a method to fortify the weak powder to produce an effective rodenticide. Also during the 1940s, The Research Laboratory tested the toxicity of red squill samples from the USDA Agricultural Research Service, which was conducting research to improve the toxicity of red squill through selective breeding.
