Abstract

In a tape for controlling crawling pests, on the first side (S1) is a carrier layer having a multitude of vertically extending structures, and on the opposite side (S2) is a means for attaching the tape to a surface. At least the first side (S1) is impregnated with a composition of A) 0.1 to 45% by weight (based on the total of A plus B) of one or more insecticides and B) 99.9 to 55% by weight (based on the total of A plus B) of an (meth)acrylate binder of one or more homo- or copolymer having units derived from one or more acrylates and/or methacrylates.

First claim

The invention claimed is:

1. A tape for controlling crawling pests, comprising on the first side (S 1 ) a carrier layer, comprising a multitude of vertically extending structures, and on the opposite side (S 1 ) means for attaching the tape to a surface,
wherein at least the first side (S 1 ) is impregnated with a composition comprising
A) 0.1 to 45% by weight (based on the total of A plus B) of one or more insecticides and
B) 99.9 to 55% by weight (based on the total of A plus B) of a (meth)acrylate binder comprising one or more homo or copolymer, comprising units derived from one or more acrylates and/or methacrylates.

2. The tape of claim 1 characterized in that the carrier layer is a hook and loop strip and the vertically extending structures are hooks or loops.

3. The tape of claim 1 , characterized in that the attachment means comprises a sticky layer and a cover layer wherein the sticky layer is attached to the second surface of the carrier layer with a first surface of the sticky layer and the cover layer is attached to a second surface of the sticky layer opposite to the first surface of the sticky layer.

4. The tape of claim 1 characterized in that the insecticide is selected from pyrethroids, chlorfenapyr, fipronil or a mixture of two of those insecticides.

5. The tape of claim 4 characterized in that the insecticide is alpha-cypermethrin.

6. The tape of claim 1 characterized in that the (meth)acrylate binder (B) is obtainable by emulsion polymerization of
B1) 20 to 93% by weight (based on B) of one or more (meth)acrylates of the formula (I)
H 2 C═CR 1 —COOR 2   (I)

 where
R1 is H or CH3 and
R2 is a linear or branched C1-C12-alkyl group;

B2) 1 to 5% by weight (based on B) of at least one monomer selected from the group consisting of N-methylolacrylamide, N-methylolmethacrylamide, N,N′-bismethylolmaleic diamide and N,N′-bismethylolfumaric diamide;
B3) 0.2 to 5% by weight (based on B) of at least one monomer selected from the group consisting of acrylic acid, methacrylic acid, vinylsulfonic acid, maleic acid and fumaric acid;
B4) 0 to 5% by weight (based on B) of at least one monomer selected from the groups
B4A) monomers of the formula (II) and/or (III),
H 2 C═CR 3 X  (II)

ZHC═CHZ  (III)

 where the symbols have the following meanings:
R3 is H or CH3,
X is Z, —CO—NH—CH2-NH—CO—CR3=CH2 or COO—CH2-CO—CH2-COOR4;
Z is CONH2, CONH—CH2-OR5, COO—Y—OH, CO-glycidyl, CHO or CO—Y—OH;
Y is C1-C8-alkylene and
R4, R5 are identical or different and are a linear or branched C1-C10-alkyl group;

B4B) allyl acrylate, methallyl acrylate, allyl methacrylate, methallyl methacrylate, diallyl maleate, dimethallyl maleate, allyl fumarate, methallyl fumarate, diallyl phthalate, dimethallyl phthalate, diallyl terephthalate, dimethallyl terephthalate, p-divinylbenzene and ethylene glycol diallyl ether;
B5) 0 to 40% by weight (based on B) of at least one monomer selected from the groups
B5A) acrylonitrile, methacrylonitrile, maleonitrile and fumaronitrile and/or
B5B) unpolar ethylenically unsaturated monomers other than B1-B4.

7. The tape of claim 1 characterized in that the (meth)acrylate binder has been crosslinked with a crosslinker which has free isocyanate groups.

8. A method for controlling crawling pests comprising the placement of a tape according to claim 1 at the perimeter of an area to be protected.

9. A method of protecting humans and domestic animals in a building from crawling pests characterized in that a tape according to claim 1 is placed in the building.

10. A method of producing a tape according to claim 1 , comprising the steps of
a) providing a tape comprising a first side (S 1 ) which is a carrier layer, comprising a multitude of vertically extending structures, and an opposite side (S 1 ) comprising attachment means for attaching the tape to a surface, and
b) impregnating the first side (S 1 ) with a composition comprising
A) 0.1 to 45% by weight (based on the total of A plus B) of one or more insecticides and
B) 99.9 to 55% by weight (based on the total of A plus B) of a (meth)acrylate binder according to the invention.
