2 Claims.

This invention relates to improvements in insect exterminators, and more particularly to a novel coating composition whichI may be applied to a cardboard card or the like.

One of the objects of the invention is to Vprovide ar in sect exterminatdr for cockroaches and other insects which do not have lungs.

A further object is to supply a simple and ef icient means for the administration of poison to such insects. l Another object is to furnish a coating composition containing a poisonous substance, and which With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, il lustrated in the accompanying drawing and more particularly pointed out in the appended claims.

In thedrawing: Fig. 1 is a perspective view Iof the cordance with the invention.

Fig. 2 is a sectional view of the same taken on card in acthe line 2--2 of Fig. 1.

In accordance with the invention I propose a liquid exterminator which can be applied to a rectangular cardboard card or the like, and which comprises the following. ingredients.

(1) A mixture composed oi the following:

a. One-half gallon of water;

b. One quart of ordinary mucilage or glue:

c; One quart of glycerin; and

d. One pound of lampblack.

These ingredients are rst thoroughly mixed.

(2) A one gallon mixture of sorghum and simple syrup at a ratio of 1:3, respectively.

. (3) Eight ounces oLdisScLlvgd yellow phosphorus which is mixed with enoug'l'i'bbdislphide to dissolve it.

(4) One pound of dextrin.

In mixing the ingredients of the composition, No. 1 mixture is first adrnixed with No. 2. After Nos. 1 and 2 have been thoroughly mixed, No. 4 is stirred in. and finally the dissolved phosphorus is added and mixed with the rest of the ingredients. This composition provides a two-gallon mixture, capable of being applied to a. card or other suitable base, and when it becomes dry, it adheres to the card or the like and lforms a 5 smooth non-sticky coating thereon. The mixture can be applied to glass, wood, or any other suitable base as it is similar in fluid characteristics to ordinary coating compositions.

As shown in the drawing, a suitable card l of l0 cardboard or the like is lpartially covered on both sides with the composition as indicated at 2 and 3. This may be ac cpnipljsherinbilcdiplilllg; one end ptioifthe cardinto the mixture,

permit Vsuch cards"'to"b` handled without the ngers coming' into contact with 'the coating.

Furthermore the blank space on the cardmay be employed for advertising data or for directions, which may be printed thereon.

Ifthe composition is applied to cards, such cards may be wrapped in Cellophane to preseve the composition until it is desired to use the card.

- Instead of using black in the No. 1 mixture, it is obvious thai-,any other coloring may be employed, but I have found that insects such as cockroaches and' waterwbugs are attited partilarlyby the black color.

It is also obvious that I may employ equivalents of the ingredients listed, and of course, may mix the ingredients in various ways without adhering. strictly to the method outlined herein, although I prefer to employ such method as it has been found effiicent in actual practice.

What I claim and desire -to secure by Letters Patent is: i

i 1. An insect exterminator consisting of a thin, stiff sheet-like, member having a large area of the `front and back-thereof completely coated with a non-tacky composition comprising a colored insecticide having as constituents thereof insect food and yellow phosphorus, the uncoated portion o said member forming a handle to facilitate placement of the exterminator.

2. An insect exterminator consisting of a thin, stift sheet-like member having a large area of the front and back thereof, its opposite edges and one adjacent end, completely coated with a non-tacky composition comprising a colored insecticide having as constituents thereof insect food and yellow phosphorus, the uncoated portion of said mem- -ber forming a handlev to facilitate placement of the exterminator.

Maxaman.
