Composition for deterring rodents comprising a capsicum oleoresin, a polyoxyethylene sorbitan fatty acid ester & a fatty acid triglyceride

摘要

A rodent-deterrent composition comprises:

(a) a capsicum oleoresin,

(b) a polyoxyethylene sorbitan fatty acid ester,

(c) a fatty acid triglyceride, and

(d) water and is in the form of an oil-in-water emulsion. It gives good overall coverage of treated areas. The capsicum oleoresin may be obtained by extraction of the fruits of Capsicum annum L. or Capsicum frutescens L. The polyoxyethylene sorbitan fatty acid ester is preferably a sorbitan monooleate or trioleate ester or a sorbitan monopalmitate ester, with about 20 units ethylene oxide. The fatty acid triglyceride is preferably a C8-10 saturated fatty acid triglyceride. A bird feed (eg one comprising seeds, nuts or a fat ball) may be rendered deterrent to rodents by applying the above composition to the feed. The two surfactants present in the composition are of food grade and are fully biodegradable.
