Abstract

Described is a method of repelling Musca domestica L. (Diptera:Muscidae), Aedes aegypti, Culex nigripalpus, Aedes atlanticus, Culex salinarius, Aedes vexans, Culex spp., Simulium spp., Psoroferia ferox, Aedes infirmatus, Drosophila melanogaster, Coccinellidae, Anopheles crucians, Psoroferia columbiae, Culicoides spp., and Aedes spp. for a finite period of time from a three-dimensional space inhabitable by these insects consisting essentially of exposing a three-dimensional space to an effective concentration and quantity of geraniol or a geraniol precursor-containing composition consisting essentially of 50-100% geraniol or a geraniol precursor (e.g., geranyloxy-1,3,2-dioxaborinane, digeranyloxydimethylsilane and geranyl glycosides, for example, geranyl 6-O-(alpha-L-rhamnopyranosyl)-beta-D-glucopyranoside) with the remainder of the composition (if indeed the composition is not 100% geraniol) being a compound selected from the group consisting of citronellol and nerol. The above-stated repellents are described to be useful as such or contained in a polymer which can be a biodegradable polymer such as compositions containing a major proportion of poly(epsilon caprolactone) homopolymers.

Claims

1. A method of repelling at least one of the species of insects:

Musca domestica L. (Diptera;

Muscidae);

Aedes aegypti;

Culex nigripalpus;

Aedes atlanticus;

Culex salinarius;

Aedes vexans;

Culex spp.;

Simulium spp.;

Psoroferia ferox;

Aedes infirmatus;

Drosophila melanogaster;

Coccinellidae;

Anopheles crucians;

Psoroferia columbiae;

Culicoides spp.; and

Aedes spp.

for a finite period of time from a three-dimensional space inhabitable by at least one of said insect species consisting essentially of the step of exposing said three-dimensional space to an effective insect species-repelling concentration and quantity of an organo-boron derivative having the structure;

##STR90##

2. The method of claim 1 wherein the organo-boron compound is contained in a polymer matrix.

3. The method of claim 2 wherein the polymer matrix is a biodegradable polymer.

4. The method of claim 3 wherein the biodegradable polymer is a polycaprolactone polymer or a polyurethane polymer.

5. The method of claim 1 wherein the organo-boron compound is initially admixed with a soap base;

the resulting mixture is formulated into a soap article; and

the resulting soap article is applied in a washing procedure.

6. The method of claim 2 wherein the polymer matrix containing the active composition of matter is formed into a core and the core is surrounded with a soap base;

and the resulting article is applied in a washing procedure.

7. The method of claim 3 wherein the biodegradable polymer matrix containing the organo-boron compound is formed into a core and the core is surrounded with a soap base;

and the resulting article is applied in a washing procedure.
