This breakdown is not necessary for sites with great or total injury. Both you and your customer may be held liable injury caused by negligent application. The injured person must prove only that he is free of negligence and did not assume the risk of pesticide exposure. Proving the applicator negligent also may be required in some cases. If damage or over-tolerance occurs, or if the owner just didn't want the site treated, you may be charged with negligent application.
Defense is very difficult.
Double-check addresses, site locations and all landmarks before you treat an area. Applying pesticides to the wrong site can be very costly. Honeybees are very important to farmers, who often have their own colonies or hives. As insects, bees can be hurt easily by many pesticides. If bees are killed in their hives by drift from your application, you can be sued for damages.
