Abstract

The present invention relates to a method of pre-rinsing laundry and treating other surfaces employing a composition that can kill bedbug eggs. The composition includes a fatty alcohol and an alcohol ethoxylate.

First claim

We claim:

1. A method of treating a textile suspected of contamination with a pest, the method consisting of:
pre-rinsing the textile with an aqueous composition consisting essentially of water, a pesticide component, and optionally one or more of an enzyme, a dye, or a fragrance, wherein pesticide components used during the pre-rinsing consist of an effective pesticidal amount of a fatty alcohol comprising 8-18 carbon atoms and an alcohol ethoxylate, and wherein the aqueous composition is effective for reducing the viable population of bed bug eggs;
draining the aqueous composition; and
washing the textile in a second aqueous composition.

2. The method of claim 1 , wherein the textile comprises clothing, bedding, a drape, a towel, a mattress, upholstery, or a combination thereof.

3. The method of claim 1 , wherein the composition is pesticidal against cockroach, bed bug, bed bug egg, ant, fly, termite, or mixture thereof.

4. The method of claim 1 , wherein the fatty alcohol comprises 10 to 14 carbon atoms.

5. The method of claim 1 , wherein the alcohol ethoxylate has a carbon chain length of about 8 to about 18 and about 6 to about 12 ethoxylate groups.

6. The method of claim 5 , wherein the alcohol ethoxylate is biodegradable.

7. The method of claim 1 , wherein the ratio of fatty alcohol to alcohol ethoxylate is about 1:5 to about 5:1.

8. The method of claim 7 , wherein the ratio of fatty alcohol to alcohol ethoxylate is about 1:1.

9. The method of claim 1 , wherein the enzyme is selected from lipase, cellulase, protease, pectinase, amylase, or a mixture thereof.

10. The method of claim 1 , wherein the effective pesticidal amount is concentration of about 0.1 wt-% to about 3 wt-%.

11. A method of treating an article suspected of contamination with a pest, the method consisting of:
applying to the article an aqueous composition consisting essentially of water, a pesticide component, and optionally one or more of an enzyme, a dye, or a fragrance, wherein pesticide components applied during the method consist of about 0.1 wt-% to about 3 wt-% of a fatty alcohol comprising 8-18 carbon atoms and an alcohol ethoxylate;
wherein the composition is effective for reducing the viable population of bed bug eggs.

12. The method of claim 11 , wherein the article comprises a hard surface selected from the group consisting of a floor, a ceiling, a window, a wall, and a combination thereof.

13. The method of claim 1 , wherein the pesticide component consists of:
1 wt-% decanol, lauryl alcohol, or tetradecyl alcohol; and
1 wt-% of a decyl/lauryl alcohol ethoxylate with 6 EO or a lauryl/myristyl alcohol ethoxylate with 7 EO.

14. The method of claim 11 , wherein the pesticide component consists of:
1 wt-% decanol, lauryl alcohol, or tetradecyl alcohol; and
1 wt-% of a decyl/lauryl alcohol ethoxylate with 6 EO or a lauryl/myristyl alcohol ethoxylate with 7 EO.
