FLY-PAPERS AND FLY-POISONS
(See also Insecticides.)
Sticky Fly-papers.
| I.— | Boiled linseed oil | 5 to 7 parts |
|---|---|---|
| Gum thus | 2 to 3 parts | |
| Non-drying oil | 3 to 7 parts |
For the non-drying oil, cottonseed, castor, or neatsfoot will answer—in fact, any of the cheaper oils that do not readily dry or harden will answer. The proper amount of each ingredient depends upon the condition of the boiled oil. If it is boiled down very stiff, more of the other ingredients will be necessary, while if thin, less will be required.
| II.— | Rosin | 8 parts |
|---|---|---|
| Rapeseed oil | 4 parts | |
| Honey | 1 part |
Melt the rosin and oil together, and incorporate the honey. Two parts of raw linseed oil and 2 parts of honey may be used along with 8 parts of rosin instead of the foregoing. Use paper already sized, as it comes from the mills, on which to spread the mixture.
| III.— | Castor oil | 12 ounces |
|---|---|---|
| Rosin | 27 ounces |
Melt together and spread on paper sized with glue, using 12 ounces glue to 4 pints water.
| IV.— | Rosin | 8 ounces |
|---|---|---|
| Venice turpentine | 2 ounces | |
| Castor oil | 2 ounces |
Spread on paper sized with glue.
Poisonous Fly-papers.—
| I.— | Quassia chips | 150 parts |
|---|---|---|
| Chloride of cobalt | 10 parts | |
| Tartar emetic | 2 parts | |
| Tincture of long pepper (1 to 4) | 80 parts | |
| Water | 400 parts |
Boil the quassia in the water until the liquid is reduced one-half, strain, add the other ingredients, saturate common absorbent paper with the solution, and dry. The paper is used in the ordinary way.
| II.— | Potassium bichromate | 10 ounces |
|---|---|---|
| Sugar | 3 drachms | |
| Oil of black pepper | 2 drachms | |
| Alcohol | 2 ounces | |
| Water | 14 ounces |
Mix and let stand for several days, then soak unsized paper with the solution.
| III.— | Cobalt chloride | 4 drachms |
|---|---|---|
| Hot water | 16 ounces | |
| Brown sugar | 1 ounce |
Dissolve the cobalt in the water and add the sugar, saturate unsized paper in the solution, and hang up to dry.
| IV.— | Quassia chips | 150 parts |
|---|---|---|
| Cobalt chloride | 10 parts | |
| Tartrate antimony | 2 parts | |
| Tincture of pepper | 80 parts | |
| Water | 400 parts |
Boil chips in the water until the volume of the latter is reduced one-half, add other ingredients and saturate paper and dry.
Fly-poison.—
| Pepper | 4 ounces |
| Quassia | 4 ounces |
| Sugar | 8 ounces |
| Diluted alcohol | 4 ounces |
Mix dry and sprinkle around where the flies can get it.
Non-poisonous Fly-papers.
II.—Mix 1 part of ground pepper and 1 part of brown sugar with 16 parts milk {348} or cream, and put the mixture on flat plates.
III.—Macerate 20 parts of quassia wood with 100 parts of water for 24 hours, boil one-half hour, and squeeze off 24 hours. The liquid is mixed with 3 parts of molasses, and evaporated to 10 parts. Next add 1 part of alcohol. Soak blotting paper with this mixture, and put on plates.
IV.—Dissolve 5 parts of potassium bichromate, 15 parts of sugar, and 1 part of essential pepper oil in 60 parts of water, and add 10 parts of alcohol. Saturate unsized paper with this solution and dry well.
V.—Boil together for half an hour
| Ground quassia wood | 18 pounds |
| Broken colocynth | 3 pounds |
| Ground long pepper | 5 pounds |
| Water | 80 pounds |
Then percolate and make up to 60 pounds if necessary with more water. Then add 4 pounds of syrup. Unsized paper is soaked in this, and dried as quickly as possible to prevent it from getting sour.
VI.—Mix together
| Ordinary syrup | 100 ounces |
| Honey | 30 ounces |
| Extract of quassia wood | 4 ounces |
| Oil of aniseed, a few drops. |
Removing The Gum Of Sticky Fly-paper.
The “gum” of sticky fly-paper, while being quite adhesive, is easily dissolved with alcohol (grain or wood) or oil of turpentine. Alcohol will not injure the shelfware, but it should not be used on varnished furniture; in the latter case turpentine should be used.
