Abstract

Methods for treating arthropods comprising depositing at least one drop of a liquid formulation containing at least one surfactant on a solid surface of an arthropod at a contact angle sufficient to cause rapid and enhanced knockdown (KD) of the arthropod. The contact angle comprises an angle formed between a resting drop of the liquid formulation and the solid surface on which the drop rests measured, after a period of about 80 milliseconds (ms) or more from the time that a drop of the liquid formulation is deposited on the solid resurface, at a contact point between a tangent line drawn on a liquid/vapor interface surface of the resting drop in contact with the solid surface and a tangent to the solid surface on which the drop rests.

Claims (18)

1. A cockroach-killing aqueous composition comprising:

about 0.1% to about 1.5%, by weight, of a primary surfactant and a secondary surfactant, wherein the primary surfactant comprises 2,5,8, 11-tetramethyl-6-dodecyn-5,8-diol ethoxylate; and wherein the secondary surfactant comprises ethoxylated 2,4, 7,9-tetramethyl-5-decyn-4,7-diol; and

about 0.001% to about 0.5%, by weight, of an insecticide ingredient; and

wherein, when at least one drop of the cockroach-killing aqueous composition is deposited on a solid surface of the cockroach, the at least one drop forms a contact angle that is less than about 40° as measured with a Krüss DSA 100 tensiometer and rests for a period of greater than about 80 milliseconds after depositing; and

wherein a knockdown (KD) rate of treated cockroaches is about 80% or greater within about two minutes after the at least one drop of the cockroach-killing aqueous composition is deposited on the solid surface of each of the cockroaches.

2. The composition of claim 1 , wherein the composition consists of the primary surfactant, the insecticide ingredient, the secondary surfactant, and water.

3. The composition of claim 1 , comprising about 0.5% to about 1.5%, by weight, of the primary surfactant and the secondary surfactant.

4. A cockroach-killing aqueous composition comprising:

about 0.1% to about 1.5%, by weight, of a primary surfactant and a secondary surfactant; wherein the primary surfactant

wherein y=8; and wherein the secondary surfactant is:

wherein y=8; and

about 0.001% to about 0.5%, by weight, of an insecticide ingredient; and

wherein, when at least one drop of the cockroach-killing aqueous composition is deposited on a solid surface of the cockroach, the at least one drop forms a contact angle that is less than about 40° as measured with a Krüss DSA 100 tensiometer and rests for a period of greater than about 80 milliseconds after depositing; and

wherein a knockdown (KD) rate of treated cockroaches is about 80% or greater within about two minutes after the at least one drop of the cockroach-killing aqueous composition is deposited on the solid surface of each of the cockroaches.

5. The composition of claim 4 , wherein the composition consists of the primary surfactant, the insecticide ingredient, the secondary surfactant, and water.

6. The composition of claim 4 , comprising about 0.5% to about 1.5%, by weight, of the primary surfactant and the secondary surfactant.

7. The composition of claim 4 , comprising about 0.5% to about 1.0%, by weight, of the primary surfactant and the secondary surfactant.

8. The composition of claim 4 , comprising about 0.05% to about 0.75%, by weight, of the first trisiloxane surfactant and about 0.05% to about 0.75%, by weight, of the second trisiloxane surfactant.
