home. You may also want to mist spray around doorways and windows. Spray the 

 foundation of the house to the point of run-off with 1 percent chlordane spray 

 made by mixing chlordane emulsion concentrate with the proper amount of water. 

 Avoid spraying near dug wells. 



This will control ants , spiders , Oriental cockroaches , and other pests that migrate 

 into the house from outdoors . 



Spiders are controlled by these foundation sprays. As they migrate into the house 

 in the fall of the year, they usually cross the foundation. Numbers of spiders 

 entering the home will be greatly reduced if the foundation has been sprayed with 

 chlordane. We are still trying to determine where the brown recluse spider can be 

 found in Illinois. Send spiders to Dr. J.D. Unzicker, Room 95, Natural Resources 

 Building, Urbana, Illinois 61801, for identification. 



Clover mites will be seeking winter quarters soon. This may be the side of your 

 house as well as behind bark on trees. For permanent control, remove grass for 

 an 18 -inch strip around the house. You can plant flowers in this 18 -inch strip 

 next spring. You can also spray the foundation and out into the yard as soon as 

 you see a few of these mites. Use chlorobenzilate or dicofol (Kelthane) . Follow 

 the directions on the lable. 



Flies are more of a nuisance in homes than they have been all summer. Cool nights 

 cause them to move in for warmth. The problem will continue for several weeks yet. 

 You can help lessen this problem by following these suggestions: 



1. In attached garages apply 0.1 percent or stronger pyrethrin or 0.5 percent 

 dichlorvos (DDVP) from a pressurized spray can around and in trash barrels and 

 around windows where flies tend to gather. 



2. Keep screens on doors and windows in good repair. 



3. Hang a plastic resin strip containing 20-percent dichlorvos (DDVP or Vapona) , 1 

 strip per 1,000 cubic feet of space, or about 1 per room. These strips will kill 

 most flies and mosquitoes for 4 to 6 weeks. Do not use these strips in kitchens 

 or other areas where food is handled. Do not use them in any room where infants, 

 ill persons, or aged persons are confined. A 0.1 percent or stronger pyrethrin 

 space spray, applied from a pressurized spray can, can be used in place of the 

 dichlorvos resin strips. Repeat treatments will be needed with the space spray. 



4. If you have had a history of problems with cluster or attic flies in winter time, 

 watch for swarms of flies under eaves and on the siding on the south and west side 

 of your home in September. If large numbers of flies appear, spray the south 



and west sides of the house where the flies are active with dimethoate (De-Fend 

 and Cygon) . Mix 1 pint of the 25-percent liquid concentrate in 5 gallons of 

 water. The spray will leave a white deposit, and on dark-colored surfaces this 

 may be objectionable for awhile. Close all windows when applying the spray. 



Walnut caterpillars are large black worms with gray hairs, that feed on the leaves of 

 walnut, hickory, butternut, oak, honey locust, willow, and some fruit trees. Colonies 

 of caterpillars feed downward on a branch and may completely defoliate it . They string 

 webs down the trunk, shed their skins, and crawl back up the tree to feed some more.
