FLY-PAPERS AND FLY-POISONS

(See also Insecticides.)

Sticky Fly-papers.

I.—Boiled linseed oil5 to 7 parts
Gum thus2 to 3 parts
Non-drying oil3 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.—Rosin8 parts
Rapeseed oil4 parts
Honey1 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 oil12 ounces
Rosin27 ounces

Melt together and spread on paper sized with glue, using 12 ounces glue to 4 pints water.

IV.—Rosin8 ounces
Venice turpentine2 ounces
Castor oil2 ounces

Spread on paper sized with glue.

Poisonous Fly-papers.—

I.—Quassia chips150 parts
Chloride of cobalt 10 parts
Tartar emetic  2 parts
Tincture of long pepper (1 to 4) 80 parts
Water400 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 bichromate10 ounces
Sugar 3 drachms
Oil of black pepper 2 drachms
Alcohol 2 ounces
Water14 ounces

Mix and let stand for several days, then soak unsized paper with the solution.

III.—Cobalt chloride 4 drachms
Hot water16 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 chips150 parts
Cobalt chloride 10 parts
Tartrate antimony  2 parts
Tincture of pepper 80 parts
Water400 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.—

Pepper4 ounces
Quassia4 ounces
Sugar8 ounces
Diluted alcohol4 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 wood18 pounds
Broken colocynth 3 pounds
Ground long pepper 5 pounds
Water80 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 syrup100 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.
