Elm leaf beetles are annoying to homeowners, particularly in the southern 

 one-half of the state. These l/k inch long, smoky, yellow or green beetles are 

 usually found between the storm and inside windows. They have spent the winter in 

 the home and are now moving outside to lay eggs on the leaves of Chinese elm trees. 

 It would help to leave the outer window up so that the beetles have ready access to 

 the outside. 



To control elm leaf beetles, brush or spray the inside window casements 

 with either 5 percent DDT or l/2 percent dieldrin in oil. Once the beetles are found 

 roaming in the house itself use a vacuum cleaner to pick them up or spray them with 

 0,1 percent pyrethrum from a pressurized spray can. 



Caution : Before applying insecticides, read the labels carefully and fol- 

 low all precautions. This not only will insure personal safety, but will also elimi- 

 nate residue hazards.
