Apply the chemical or biological pesticide to select infested areas; don't spray the entire lawn all at once. Chemical pesticides can kill many of the predator bugs that keep the lawn healthy, along with other creatures such as birds. Only if targeting infested areas doesn't work should you try spraying the entire lawn with a biological or chemical pesticide.
