Abstract

Synergistic and residual pesticidal compositions containing synergistic and residual mixtures of plant essential oils and/or their constituents, plant essential oils and/or their constituents in admixture with known active pesticidal compounds or plant essential oils and/or their constituents in admixture with other compounds not previously used as active ingredients in pesticidal formulations, such as, for example, so called signal transduction modulators. In addition, the present invention is directed to a method for controlling pests by applying a pesticidally effective amount of the above synergistic and residual pesticidal compositions to a locus where pest control is desired.

Claims

1. A method for killing or controlling a pest, comprising:

applying a pesticidally-effective amount of a pesticidal composition to the pest or to a locus where killing or control of the pest is desired

wherein the pesticidal composition comprises a pesticidally-acceptable carrier in admixture with a pesticidally-effective amount of a pesticidally-active agent consisting of a mixture of pyrethrum and eugenol with the proviso that no other pesticidally-active agent is present and wherein the ratio of EUGENOL to PYRETHRUM is 5;

1 or higher.

2. The method of claim 1, wherein the pesticidally-active agent interferes with neurotransmission in invertebrates.

3. The method of claim 2, wherein the pesticidally-active agent interferes with octopamine receptor sites in invertebrates.

4. The method of claim 1, wherein the pest is a cockroach.
