GRASSHOPPERS AND OTHER INJURIOUS INSECTS OP 1911 AND 1912. 81 



ficiilt to eradicate. Particularly is this the case when it has taken 

 possession of a flat or hotel, where, by running along the water 

 pipes, it can avoid danger, traveling from room to room or from 

 house to house. 



This Division has tried various traps, and practically all the pro- 

 prietary remedies, besides certain poison baits of our own invention, 

 only to find that almost any remedy is useless as soon as this insect 

 realizes, as it appears to, that it (the remedy) is aimed toward its 

 extermination. We find, however, that they are frequently caught 

 in small numbers in the Hodge Fly Traps. 



Perhaps the most important advice to off'er in connection with 

 this insect is that the housekeeper should at the very first appear- 

 ance of the pest, begin a war of extermination immediately. Every 

 day of delay means a probable increase in the ranks of the enemy, 

 and, as stated above, when once well established, it is a Herculean 

 task to eradicate them. A careful and painstaking housekeeper, 

 therefore, who aims at cleanliness in pantry and kitchen, has the 

 advantage over one of more easy-going habits. 



Powdered borax in some form appears to be the chief agent to be 

 used against them, and probably forms tha base of the well adver- 

 tised and rather high priced roach powders. 



A private house badly infested, where the housekeeper followed 

 the advice of this Division, was completely freed of the pest by a 

 faithful and continuous use of powdered borax. This was scat- 

 tered along the mop-board in the kitchen, about cracks and crevices 

 wherever they occurred, in kitchen drawers, about the water piper, 

 kitchen sink, etc., every evening after the day's work was finished, 

 and continued for about a week. 



We, and others, have found that a compound known as "Hoop- 

 er's Fatal Food," carried by druggists, is probably the best remedy 

 for the cockroach evil, if its use is persisted in. It comes in flat 

 cans, and should be dusted liberally and frequently in places where 

 these insects occur. 



ANTS IN HOUSE AND GARDEN. 



The few species of ants found in this state constitute a very 

 small fraction of the ant fauna of the world, represented as it is by 

 probably nearly or quite 4,000 species, 2,000 or more of which are 

 already known. 



All or our common ants swarm at the mating season, at which 

 time the males and females are winged, losing these temporary ap-
