Millipedes can be a problem at this time of year, especially in newly de- 

 veloped housing areas that were formerly wasteland or pastures. These many-legged, 

 brown, wirelike insects migrate from waste areas to areas in and around houses. If 

 they become a problem, use carbaryl as a spray on the foundation of the house and out 

 into the yard for three or four feet. 



Sod webworm moths can be seen flying over lawns at dusk. These buff- 

 colored moths have been laying eggs for the past two or three weeks. If sod webworm 

 larvae are going to be a problem, they should be causing damage now. Brown, irregu- 

 larly shaped patches will appear in the lawn. 



Examine the lawn carefully for larvae. The silken cases or tunnels and 

 freshly cut pieces of grass are the easiest means of detection. During July when 

 there was little rain, the well -watered lawns remained green and moths laid eggs in 

 them. But since many lawns have become green again after the rains, egg laying has 

 spread over a more general area. First -generation sod webworm numbers were much 

 lower this year than in the three previous years. 



If treatment is necessary, use 2 pounds of carbaryl or one pound of diazinon 

 per 10,000 square feet in at least 25 gallons of water. 



Caution to Those Using Insecticides 



Before applying insecticides, read the labels carefully and follow all 

 precautions. This will not only insure personal safety, but will also eliminate 

 residue hazards.
