Insecticidal compositions with disinfectant
View Patent ↗Insecticidal compositions having insecticide and disinfectant activity are provided. Preferably, the insecticidal composition contains both an insect control agent and a disinfectant. Particularly low levels (i.e., below 20%) of at least one hydrocarbon are introduced as a solvent. The insecticidal compositions further comprise an emulsifier, buffer and antifoaming agent. These insecticidal compositions are particularly suitable for delivery in a spray for non-industrial environments. In use, the present insecticidal compositions may be applied directly to or in or around any area where it is desired to control pestiferous insects and the fungi, bacteria, viruses and other contaminants associated with them.

6. The composition of claim 1 , wherein the antifoaming agent comprises a silicone or polydimethylsiloxane emulsion and is present in an amount of 0.02 to 0.08% by weight based on the weight of the composition.
7. The composition of claim 1 , wherein the composition is in a spray formulation.
8. The composition of claim 1 , wherein the composition has a pH of 6 to 8.
9. The composition of claim 1 wherein said water is present in an amount of at least 80% by weight based on the weight of the composition.
10. The composition of claim 1 , wherein the water is present in an amount of 90.0% to 99.9% by weight based on the weight of the composition.
11. A method of controlling unwanted insects comprising the steps of
providing the insecticidal composition of claim 1 ; and
applying the composition to the insects or in a habitat capable of being utilized by said insects, in an effective amount.
12. The method of claim 11 , wherein the insects are selected from the group consisting of carpenter ants, German cockroaches, house flies, and house crickets.
13. An insecticidal composition comprising
beta-cyfluthrin in an amount of 0.02 to 1.0% by weight based on the weight of the composition;
o-phenylphenol or a sodium salt thereof in an amount of 0.2 to 0.5% by weight based on the weight of the composition;
a hydrocarbon solvent in an amount of less than 20% by weight based on the weight of the composition;
an emulsifier comprising a mixture of anionic/nonionic detergent blends wherein each blend component is present in an amount of less than 2% by weight based on the weight of the composition;
optionally a buffer;
optionally an anti-foaming agent; and
water.
14. The composition of claim 1 , wherein the beta-cyfluthrin is present in an amount of 0.05% by weight based on the weight of the composition.
15. The composition of claim 1 , wherein the o-phenylphenol or a sodium salt thereof is present in an amount of 0.30% by weight based on the weight of the composition.
16. The composition of claim 1 , wherein
the beta-cyfluthrin is present in an amount of 0.05% by weight based on the weight of the composition, and
