As a rule-of -thumb guide in fields where pods are not filled, we feel an average 

 of 6 or more worms per linear foot of drill row justifies treatment. Use 1 1/2 

 pounds of toxaphene or 1 pound of carbaryl per acre for control . Do not feed 

 toxaphene- treated forage to dairy animals or livestock fattening for slaughter. 

 Do not apply toxaphene to fields adjacent to fish-bearing waters. 



Forage Insects 



New seedings of alfalfa may be severely damaged by the garden webworm and other 

 leaf-feeding caterpillars. Watch new seedings closely, and at first sign of dam- 

 age apply a spray of carbaryl at 1 pound of actual per acre, or toxaphene at 

 1 1/2 pounds of actual per acre. Do not feed toxaphene -treated forage to dairy 

 cattle or livestock fattening for slaughter. 



Homeowner Insect Problems 



Flies are more of a problem in homes than they have been all summer. The cool 

 nights cause them to move indoors for warmth. To lessen fly annoyance in and 

 around the home follow these two steps : 



1. In attached garages, under breezeways, or on porches, hang one dimetilan fly 

 band (Snip fly band) per 75 square feet. Wipe the bands every two weeks with 

 a damp rag to remove dust deposits. Flies landing on the bands will be killed 

 before they can enter the house. The bands will continue to remain active for 

 a year or two. 



2. Hang one 20-percent dichlorvos (DDVP, Vapona) plastic resin strip for every 

 1,000 cubic feet of space (about one per room) in the kitchen and in other 

 rooms where flies congregate. The dichlorvos vaporizes slowly, killing flies 

 and mosquitoes without harming people or pets. These strips are effective 

 for about 4 to 6 weeks. As an added precaution, hang the strips out of reach 

 of children and away from fish bowls or food counters . 



In place of the dichlorvos resin strips, you can use a 0.1 -percent pyrethrum space 

 spray, applied from a pressurized can, for quick knockdown of flies and mosquitoes. 

 Repeat treatments will be needed with the space spray. 



Millipedes are moving into homes from shrubbery beds, lawns, storm sewers, and 

 nearby wasteland areas having a heavy trash cover. These brown, hard-shelled, 

 slow-moving worms have two pairs of legs per body segment . They often curl up in 

 a tight coil and prefer dark, damp areas in basements and garages. When numerous, 

 they wander throughout the house. Cool weather causes them to seek shelter indoors, 



In cases of heavy migration, spray lawns and shrubbery beds with carbaryl or diazi- 

 non. This provides a barrier zone in which they are killed and prevents them from 

 gaining access to the home. If migration persists, repeat the treatment in a week 

 or two. For minor problems, limited spraying of a 3- to 4-foot -wide area around 

 the house foundation should be adequate. Apply approximately 2 pounds of actual 

 carbaryl or 1 pound of actual diazinon in 25 gallons of water for each 10,000 

 square feet of area treated. This same treatment will control sod webworms and 

 leafhoppers in lawns, but it is ineffective against grubs. 



Mosquitoes have been heavy in many areas through much of the summer and populations 

 continue to remain high. The following suggestions will help to lessen mosquito 

 numbers: (1) Eliminate standing water in such places as eave troughs, old tires,
