If you have a history of soil insect problems in your vegetable garden , apply 

 diazinon at 1 ounce per 1,000 square feet before planting. To do this, mix 1/4 

 pint (4 fluid ounces) of 25-percent diazinon emulsion in enough water (usually 

 2 to 5 gallons) to cover 1,000 square feet and then rake into the soil. 



Keep outdoor insects out of your home by spraying the outside foundation wall of 

 your home with 2-percent chlordane. Ants, spiders, centipedes, crickets, and other 

 insects invade homes in search of food or for shelter. You can lessen the use of 

 insecticides in the home by controlling these insect invaders before they enter. 



Buy chlordane as a liquid emulsion concentrate and dilute it with water to the 

 proper strength (1 pint of 45-percent chlordane liquid concentrate in 5 gallons 

 of water gives a 2-percent solution) . Spray the foundation from the sill to the 

 soil until the spray runs off. Also spray 2 to 5 inches of soil next to the foun- 

 dation wall. Spray cracks or expansion joints along porches and around steps and 

 also along the edges of sidewalks and driveways. In houses with crawl spaces, 

 treat the inside of the foundation wall, as well as the outside, and also spray 

 support pillars. The average house requires about 3 gallons of finished spray. 

 Do not spray near wells or cisterns. Do not spray shrubbery or flowers, because 

 the oil may burn the foliage. Repeat the treatment in late sunnier for protection 

 in the fall. 



CAUTION: BEFORE APPLYING INSECTICIDES, READ THE LABELS CAREFULLY AND FOLLOW ALL 

 PRECAUTIONS. THIS WILL NOT ONLY INUSRE PERSONAL SAFETY, BUT WILL ALSO PREVENT 

 RESIDUE HAZARDS.
