up boxelder bugs as they emerge and become active on warm spring days, use a vacuum 

 sweeper or broom and a dustpan indoors. A 0.1 -percent pyrethrin household spray will 

 give temporary control, but repeated treatments will be needed. To control infesta- 

 tions along the outside foundation of the house, spray with diazinon, carbaryl, or 

 malathion. 



Clover mites will soon leave their winter hibernation sites. When their hiding places 

 beneath siding and in cracks and crevices are warmed by the sun, these mites move to 

 window sills and walls on the east and south sides of the house. Clover mites are 

 tiny, orange- to-black moving specks about the size of the period at the end of this 

 sentence. They cover furniture, curtains, window sills, and walls. Although harm- 

 less, clover mites leave an unsightly stain when mashed. 



Pick them up with a vacuum cleaner or use an 0.1-percent pyrethrin spray from a pres- 

 surized spray can for a quick knockdown. Before fall, remove the grass, clover, and 

 weeds next to the foundation so there is a strip of soil at least 18 inches wide. This 

 bare soil will serve as a barrier to the mites. 



SPECIAL NOTE TO PESTICIDE DEALERS 



Pesticides bearing the skull and cross bones are very highly toxic and should be han- 

 dled with care. Caution all your customers to do this. Tell them never to reuse an 

 empty pesticide container. 



During the past ten years, there have been only 25 accidental deaths from pesticides 

 in Illinois. Although this is a remarkable safety record, some of these deaths could 

 have been prevented. In several instances, highly poisonous pesticides were placed in 

 soft drink bottles. Small children later drank from them. Never put a pesticide in 

 anything but its original, well-marked container. Warn your customers about this.
