Poisoned Baits 127 



There are many brands of this article upon the market and 

 all are fairly pure and equally effective in controlling insect 

 pests. The ready made arsenate of lead is all ready to use 

 by diluting one to three pounds of the paste with fifty gal- 

 lons of water. 



As the commercial brands of arsenate of lead come in 

 cans or kegs and in the form of a stiff white paste quite 

 like white lead paint, it is made more difficult to handle 

 by the paste drying out. For this reason many persons 

 who have only a small amount of spraying to do prefer to 

 make up their own arsenate, as it is easily made and is 

 slightly cheaper than the commercial brands. Arsenate of 

 lead can be made by the following formula: 



Arsenate of soda, 4 ounces. 

 Acetate of lead, 11 ounces. 

 Water, 15-20 gallons. 



Dissolve the arsenate of soda in two quarts of water 

 and the acetate of lead in four quarts of water in wooden 

 vessels. When dissolved pour them into the required 

 amount of water. A milk white material will result, and 

 it is ready to use. This material can be used at a greater 

 strength without injuring the foliage of plants than can 

 any of the other spray poisons. It can be added to bor- 

 deaux mixture or to lime-sulphur in the same proportion 

 as when water is used. 



Poisoned Baits 



Sow-bugs, grasshoppers, cut worms and some other in- 

 sects can be destroyed by poisoned baits. There are va- 

 rious forms of this method of destroying insects. Grass 

 leaves dipped in Paris green or arsenate of lead is often 

 an effective means of getting rid of cut worms. As a 

 means of destroying grasshoppers a bran-arsenic mash is 

 very successful and is made as follows: 



White arsenic, 1 pound. 

 Brown sugar, 1 to 2 pounds. 

 Bran, 6 pounds.
