One control method to avoid is the beetle traps sold in many stores. Research performed by many universities has shown that the pheromone traps attract more beetles to a property than they catch. In essence, you are sending the beetles a message to come eat in your yard. If you have a large property (several acres in size) you can use the traps to draw the beetles away from your gardens.
