INSECTS INJURIOUS TO MAN AND IN HOUSEHOLD 655 



bags for the storage of woolen articles are of value. Cold storage 

 is one of the safest forms of protection through the summer 

 months. Any box which can be made practically air-tight will 

 afford protection if the articles are uninfested when the boxes are 

 closed. 



We have found that storing in rooms where the temperature 

 is uniformly high, above 90 at all times, will afford as complete 

 protection as the cold storage. 



Miscellaneous Household Insects 



The Silverfish or Fish-Moth (Lepisma saccharalis or domestica) 

 is an insect which sometimes defaces papers or gets into food 

 materials but is not usually serious. 

 The general belief is that they feed on 

 starchy materials by preference but will 

 feed on animal matter. 



The House Centipede (Scutigera 

 forceps), not an insect at all but a cen- 

 tipede, is a slender-bodied animal with 

 many very long legs frequently seen 

 running on walls and ceilings. It is 

 not injurious, except to delicate nerves, 

 as it feeds upon flies and other insects. 



Book-lice (Corrodentia), are minute 

 louse-like insects, almost colorless andi 

 just large enough to be seen, which 

 run over old -books and papers and 

 sometimes may deface them slightly. 

 They, however, do little damage and 

 need not be feared. FlG - 575. Adult silverfish

 sometimes do considerable injury by mining into the foundation 

 timbers, floors and even walls of houses. They have been known 

 to cause the collapse of large buildings and often necessitate 

 replacing foundations and floors in the southern states. They 

 injure plants also, injury having been noted on the orange, on 

 plum and particularly on apple-seedlings in the middle-west.
