## Abstract

Described herein is a method for controlling insects where a composition including an insecticide and a polymer are applied to soil, where the polymer is formed from an initiator and a plurality of C2 to C6 alkylene oxide units, and where the initiator is an aliphatic polyol with at least three hydroxyl groups. Also described herein is a composition including an insecticide and a polymer, where the polymer is formed from an initiator and a plurality of C2 to C6 alkylene oxide units, and where the initiator is an aliphatic polyol with at least three hydroxyl groups.

## Claims

### Claim 1

A method for controlling insects wherein a composition comprising an insecticide and a polymer are applied to soil, wherein the polymer is foirired from an initiator and a plurality of C2 to C6 alkylene oxide units, and wherein the initiator is an aliphatic polyol with at least three hydroxyl groups.

### Claim 2 (depends on 1)

The method according to claim 1 wherein the insects are soil dwelling insects.

### Claim 3 (depends on 1)

The method according to claim 1 wherein the insects are termites or ants.

### Claim 4 (depends on 1)

The method according to claim 1 wherein a weight ratio of the insecticide to the polymer is in the range from 5:1 to 1:50.

### Claim 5 (depends on 1)

The method according to claim 1 wherein the soil is present under a building or within a radius of 50 m thereof.

### Claim 6 (depends on 1)

The method according to claim 1 wherein the composition is applied to soil by soil injection.

### Claim 7 (depends on 1)

The method according to claim 1 wherein the composition is applied in form of an aqueous dilution which comprises from 100 to 10,000 ppm of the polymer.

### Claim 8 (depends on 1)

The method according to claim 1 wherein the initiator is an aliphatic polyol with three or four hydroxyl groups.

### Claim 9 (depends on 1)

The method according to claim 1 wherein the alkylene oxide units comprise ethylene oxide and/or propylene oxide.

### Claim 10 (depends on 1)

The method according to claim 1 wherein the polymer has a molecular weight of 400 to 15,000 g/mol.

### Claim 11 (depends on 1)

The method according to claim 1 wherein the insecticide has a solubility in water at 20° C. of up to 10 g/l.

### Claim 12

A composition comprising an insecticide and a polymer, wherein the polymer is formed from an initiator and a plurality of C2 to C6 alkylene oxide units, and wherein the initiator is an aliphatic polyol with at least three hydroxyl groups.

### Claim 13 (depends on 12)

The composition according to claim 12 wherein a weight ratio of the insecticide to the polymer is in the range from 5:1 to 1:50.

### Claim 14 (depends on 12)

The composition according to claim 12 wherein the insecticide is a termiticide.

### Claim 15 (depends on 12)

The composition according to claim 12 wherein the initiator is an aliphatic polyol with three or four hydroxyl groups.

### Claim 16 (depends on 12)

The composition according to claim 12 wherein the polymer has a molecular weight of 400 to 15,000 g/mol.

### Claim 17 (depends on 12)

The composition according to claim 12 wherein the insecticide has a solubility in water of up to 10 g/l.
