Abstract

The present invention relates to a rodenticide bait composition comprising a calcium salt and a dehydrant; wherein the calcium salt is selected from the group consisting of calcium carbonate, calcium citrate, calcium acetate, calcium benzoate, calcium octanoate, calcium stearate, calcium silicate, calcium oxide silicate, calcium sulfate, calcium chloride, calcium bromide, calcium iodide, calcium lactate, calcium gluconate, calcium oxalate, calcium phosphate and combinations of two or more thereof; wherein the calcium salt is present in an amount of less than 20 wt. % based on the total weight of the composition; wherein the dehydrant comprises one or more sources of cellulose and one or more sources of phospholipids.

First claim

The invention claimed is:

1. A rodenticide bait composition comprising:
between 5 wt. % and 18 wt. % of a calcium salt, based on the total weight of the composition, wherein the calcium salt is selected from the group consisting of calcium carbonate, calcium citrate, calcium acetate, and combinations of two or more thereof; and
between 40 wt. % and 80 wt. % of a dehydrant, based on the total weight of the composition, wherein the dehydrant comprises:
between 70 wt. % and 95 wt. % of one or more sources of cellulose, based on the total weight of the dehydrant,
between 1 wt. % and 15 wt. % of one or more sources of phospholipids, based on the total weight of the dehydrant, wherein the one or more sources of phospholipids is a vegetable oil, and
at least one carrageenan; and

wherein the rodenticide bait composition is free of cholecalciferol.

2. The rodenticide bait composition according to claim 1 , wherein said one or more sources of cellulose is selected from the group consisting of carboxymethyl cellulose, cardboard, cellulose acetate, regenerated cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, methylcellulose, pectin, sodium carboxymethyl cellulose, cornmeal, corn grits, corn cobs, corn gluten meal, and combinations thereof.

3. The rodenticide bait composition according to claim 1 , wherein the vegetable oil, is selected from the group consisting of soybean oil, castor oil, linseed oil, cottonseed oil, and combinations thereof.

4. The rodenticide bait composition according to claim 1 , wherein said dehydrant comprises between 5 wt. % and 40 wt. % of said carrageenans, based on the total weight of the dehydrant.

5. The rodenticide bait composition according to claim 1 , wherein the proportion of carrageenans:one or more sources of cellulose is between 1:1 and 1:10.

6. The rodenticide bait composition according to claim 1 , wherein said rodenticide bait composition further comprises a source of endogenous gas selected from the group consisting of sodium percarbonate, magnesium percarbonate, zinc percarbonate, calcium peroxide, calcium percarbonate, magnesium peroxide, zinc peroxide, sodium perborate, potassium monopersulfate, tetraacetylethylenediamine, sodium bicarbonate or combinations thereof; and
wherein the source of endogenous gas is present in an amount of between 5 wt. % and 20 wt. %, based on the total weight of the composition.

7. The rodenticide bait composition according to claim 1 , wherein the composition is in the form of a solid.

8. A package comprising the rodenticide bait composition according to claim 1 .

9. A method for exterminating a rodent, the method comprising administering to the rodent the rodenticide bait composition according to claim 1 .

10. A method for preparing a rodenticide bait composition, the method comprising:
blending at least one calcium salt and a dehydrant with at least one carrageenan and one or more further ingredients to form a rodenticide bait composition comprising between 5 wt. % and 18 wt. % of the calcium salt, based on the total weight of the composition and between 40 wt. % and 80 wt. % of the dehydrant, based on the total weight of the composition,
wherein the at least one calcium salt is selected from the group consisting of calcium carbonate, calcium citrate, calcium acetate, and combinations of two or more thereof; and
wherein the dehydrant comprises:
between 70 wt. % and 95 wt. % of one or more sources of cellulose, based on the total weight of the dehydrant, and
between 1 wt. % and 15 wt. % of one or more sources of phospholipids, based on the total weight of the dehydrant, and wherein the one or more sources of phospholipids is a vegetable oil; and

wherein the rodenticide bait composition is free of cholecalciferol.

11. The rodenticide bait composition according to claim 1 , wherein said one or more sources of cellulose is corn cobs or corn gluten meal.

12. The rodenticide bait composition according to claim 1 , wherein said one or more sources of phospholipids is soybean oil.

13. The rodenticide bait composition according to claim 1 , wherein said dehydrant comprises between 5 wt. % and 10 wt. % of said one or more sources of phospholipids, based on the total weight of the dehydrant.

14. The method of claim 10 , wherein said one or more sources of cellulose is corn gluten meal, and/or said one or more sources of phospholipids is soybean oil.

15. A rodenticide bait composition comprising:
at least one calcium salt present at a concentration between 5 wt. % and 18 wt. %, wherein the calcium salt is selected from the group consisting of calcium carbonate, calcium citrate, calcium acetate, and combinations of two or more thereof;
at least one source of cellulose present at a concentration between 28 wt. % to 76 wt. %;
at least one vegetable oil present at a concentration between 0.4 wt. % and 12 wt. %;
at least one carrageenan present at a concentration between 2 wt. % to 32 wt. %, and wherein a proportion of carrageenan:one or more sources of cellulose is between 1:1 about 1:10;
at least one source of endogenous gas present at a concentration between 5 wt. % and 20 wt. %;
at least one filler; and
wherein the rodenticide bait composition is free of cholecalciferol.

16. The rodenticide bait composition of claim 15 , wherein:
the one or more sources of cellulose is selected from the group consisting of carboxymethyl cellulose, cardboard, cellulose acetate, regenerated cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, methylcellulose, pectin, sodium carboxymethyl cellulose, cornmeal, corn grits, corn cobs, corn gluten meal, and combinations thereof;
