How to Kill Crawdads in a Lawn
- 1). Use general use lawn pesticides used for insect pest in turf to kill crawdads. There are no registered pesticides specifically for use with crawdads.
- 2). Mix together 1 lb. of chloride of lime in 3 gallons of water. Stir until dissolved. Chloride of lime is also referred to as bleaching powder. Using a compressed air sprayer or watering can with the sprayer removed, pour 1 to 2 oz. of the solution down each burrow. Press the top the burrow closed by bringing the earth together with your foot. As cited by the Ohio State University Extension site, this will take only a few hours to kill the crawdads.
- 3). Use a turpentine and soap solution as an alternate method by mixing 2 qts. of turpentine and ¼ lb. of powdered soap in 1 qt. of water. Mix together one part of this solution to 50 parts of water and use in same manner as the chloride of lime to kill crawdads.
