They aren&#x27;t particularly expensive either.<p>But yes, you can&#x27;t use natural predators. You basically need to introduce them, let them do their jobs, and then most of the predators will die once the problem is controlled for.<p>But give its a $50 problem, its not a very expensive problem and on par with pesticide costs.
