## Abstract

A method of combating bed bugs and/or other insects in a locus containing or susceptible to presence of same, in which a DMSO-containing formulation is applied to the locus. Various pesticidal compositions are disclosed as useful for such purpose, including compositions in which DMSO is in combination with an alcohol and/or another pesticidal active agent. Compositions of the disclosure can be applied to a variety of loci, to effectively eradicate bed bugs for extended periods of time.

## Claims

### Claim 1

A method of combating bed bugs in a locus, said method comprising applying to said locus and/or bed bugs therein a cidally effective amount of a formulation comprising dimethyl sulfoxide (DMSO), wherein the formulation is free of any additional insecticidal active ingredient.

### Claim 2 (depends on 1)

The method of claim 1, wherein the formulation further comprises a diluent.

### Claim 3 (depends on 2)

The method of claim 2, wherein the diluent has a lower boiling point than DMSO.

### Claim 4 (depends on 3)

The method of claim 3, wherein the diluent is selected from the group consisting of water, alcohols, ketones, aldehydes, and ethers.

### Claim 5 (depends on 3)

The method of claim 3, wherein the diluent is selected from the group consisting of water, isopropyl alcohol, acetones, and methanol.

### Claim 6 (depends on 3)

The method of claim 3, wherein the diluent is ethanol.

### Claim 7 (depends on 6)

The method of claim 6, wherein the formulation comprises ethanol in an amount of from 0.5% to 99.5% by volume, based on total volume of DMSO and ethanol.
