INSECT PESTS OF THE HOUSEHOLD. 



eggs are laid in a pod or egg-case (/, g) from which

the young roaches hatch. They pass through vari- 

 ous moults as represented at a, b, c, d, and do not ac- 

 quire wings until full-grown (e,f, h), when they are 

 nearly two-thirds of an inch long. The other roaches 

 develop in a similar way. 



Remedies. — The best remedy for these pests is a 

 good quality of insect powder, such as Buhach. In 

 recommending this, Dr. Riley says : 



" Just before nightfall go into the infested rooms 

 and puff it into all crevices, under base-boards, into 

 drawers and cracks of old furniture — in fact wher- 

 ever there is a crack — and in the morning the floor 

 will be covered with dead and dying or demoralized 

 and paralyzed roaches, which may easily be swept 

 up or otherwise collected and burned. With clean- 

 liness and persistency in these methods the pest may 

 be substantially driven out of a house, and should 

 never be allowed to get full possession by immi- 

 grants from without."
