or 2 -quart hand sprayer that delivers a 

 continuous spray. The sprayer should 

 be equipped with a nozzle that can be 

 adjusted to control the size of the spray 

 particles. To insure proper coverage, 

 hold the nozzle within a few inches of 

 the object or surface being sprayed; this 

 is necessary because the sprayer operates 

 under low pressure. 



A 1- or 2-gallon garden-type com- 

 pressed-air sprayer is recommended for 

 treating several rooms or beds. The disk 

 opening should be smaller than that nor- 

 mally used when spraying plants. Pres- 

 sure should be light to moderate except 

 when treating mattresses or upholstered 

 furniture. High pressure causes the 

 sprayer to produce fine particles or mist.

If You Need the Services of a Pest-Control Operator . . . 



Bed bugs in hotels, apartments, and other multiple-type dwelling places 

 may spread quickly from one unit to another. If they are found in one unit, 

 the owner or manager of the building should have all the units inspected, 

 and should arrange for control of any infestations revealed by the inspection. 



As a rule, commercial pest-control operators are best qualified to inspect 

 multiple-type dwelling places and to control infestations in them. Also, it 

 is often advantageous to call in a pest-control operator to eliminate heavy 

 general infestations in private homes. 



After an infestation is under control, it may be advisable to have the pest- 

 control operator check at regular intervals. In this way new infestations may 

 be detected and eliminated before they spread.
