PRECAUTIONS 



Insecticides arc poisonous. Handle 

 them with care. Follow directions and 

 heed all precautions on the container 

 label. 



After working with concentrated in- 

 secticides, wash all exposed surfaces of 

 the body with soap and water. Put on 

 clean clothing. 



Do not contaminate foods and food 

 utensils with insecticides. 



Avoid unnecessary exposure to insecti- 

 cides while applying them. 



Keep doors and windows open in 

 order to avoid excessive breathing of the 

 spray mist and also to reduce fire hazard. 



Do not apply oil sprays near an open 

 flame or a pilot light. 



Store insecticides in a dry place out of 

 reach of children and animals. 



Control in animal and 

 poultry houses 



In animal and poultry houses, good 

 sanitation practices and proper construc- 

 tion reduce the number of places in which 

 bed bugs can hide. 



If an insecticide is needed, follow these 

 recommendations: 



• Animal houses. — Apply any of the 

 sprays referred to in the table on page 

 5, or apply a dust. A lindane or mal- 

 athion spray should contain the higher 

 of the two percentages of insecticide 

 given in the table. A pyrethrum dust 



should contain 1 percent of pyrethrins 



or 0.2 percent of pyrethrins plus a syner- 

 gist. Proper strengths of other dusts: 

 DDT, 10 percent; lindane, 1 percent; 

 malathion, 4 percent. 



• Poultry houses. — Apply a 0.5- 

 percent lindane spray, a 1-percent mala- 

 thion spray, or a 0.2-percent pyrethrins 

 spray (see table on p. 5). Except for 

 DDT, the dusts recommended for appli- 

 cation in animal houses are also suitable. 



Apply the spray or dust to all inside 

 su r faces. Get it in all crevices. Spray 

 should be coarse (see "Kinds of Spray- 

 ers," p. 6) and should be applied to 

 the point of runoff. 



Bed bugs often become established in 

 laboratories where animals or birds are 

 kept for experimental purposes. Where 

 the nature of the experiments is such 

 that insecticide contamination must be 

 avoided, a pyrethrum spray or dust 

 should be used, especially in tre£ ing 

 cages. However, in most laboratories 

 DDT, lindane, or malathion can be ap- 

 plied to cracks, corners, and other hiding 

 places without contaminating the caged 

 animals.
