To entice by cheese.— Get a piece of old cheese, and grate it fine 

 into a feeder, sprinkle it over with a little powdered lump sugar, 

 cover the feeder over with moss, as hefore, examine every morning 

 and destroy them. 



To entice by fruit. — Get some slices of ripe fruit, as apricot, plum, 

 pear, apple, or any sort afforded by the season, always, however, add- 

 ing a little lump sugar if the fruit be sour ; place in a feeder, cover, 

 and examine as before. 



To entice by bean-stalks. -Cut up old bean-stalks in lengths about 

 nine inches each, and lay them in different parts of the frame ; blow 

 them every morning, and destroy the woodlice. 



To decoy with Brio?iy-root.— Cut up briony-root (Brionia dioica) 

 into slices, put in feeders, cover the feeders with moss as before, exa- 

 mine regularly, and destroy the woodlice. 



To decoy merely by shelter.— When there is not much shelter 

 in the frame infested, place handfulls of hay or dry moss here and 

 there every evening, remove them away in the morning, and destroy 

 the woodlice. 



A live toad kept in the frame will keep it free from them.
