Gellable ant bait matrix
View Patent ↗Ant foods mixed together in a matrix suitable to be used as baits for ants are provided. This ant matrix is preferred by ants over naturally-occurring foods such as other known ant matrices. It comprises protein, carbohydrate, fat and sterol as ant-preferred nutrients and uric acid as a bait enhancing agent is carried in a unique gel system that is specifically attractive to insects. Methods of controlling ants using such matrices to deliver ant toxins are also provided.
1. A gelatinous bait matrix for attracting and killing ants comprising:
a) about 40-70% by weight water;
b) about 0.01-0.05% by weight a calcium salt;
c) about 2-5% by weight at least one pectin or plant derived polysaccharide;
d) at least one toxicant that is effective against ants; and
e) about 20-40% by weight an ant attractant mixture which is dry mixture comprising:
i) about 0.01-10% by weight, based upon the total weight of the attractant mixture, of at least one cellulose;
ii) about 1-10% by weight, based upon the total weight of the attractant mixture, of at least one sugar;
iii) about 0.5-5% by weight, based upon the total weight of the attractant mixture, of at least one plant starch;
iv) about 30-60% by weight, based upon the total weight of the attractant mixture, of instant nonfat dry milk;
v) about 20-60% by weight, based upon the total weight of the attractant mixture, of egg yolk;
vi) about 0.0001-0.010% by weight, based upon the total weight of the attractant mixture, of a sterol compound;
vii) about 0.1-1.0% by weight, based upon the total weight of the attractant mixture, of uric acid; and
viii) about 2-15% by weight, based upon the total weight of the attractant mixture, of at least one plant-based oil.
2. The gelatinous bait matrix according to claim 1 , wherein the calcium salt is selected from the group consisting of calcium chloride, calcium propionate, and calcium carbonate.
3. The gelatinous bait matrix according to claim 1 , wherein the at least one toxicant is selected from the group consisting of boric acid, fipronil, hexaflumoron, hydramethylnon, diflubezuron, suframid, avermectin, abamectin, pyrethroid compounds, and combinations of the foregoing.
4. The gelatinous bait matrix according to claim 3 , wherein the at least one toxicant is present in the gelatinous bait matrix at a concentration of about 0.001-10% by weight, based upon the total weight of the bait matrix.
5. The gelatinous bait matrix according to claim 3 , wherein the at least one toxicant is boric acid.
6. The gelatinous bait matrix according to claim 1 , wherein the toxicant is present in the gelatinous bait matrix at a concentration of from about 0.001 to 10% by weight, based upon the total weight of the bait matrix.
