For repelling insects: Swat fly swatter for the patio If you want to sit comfortably on the patio while eating and don't want to be bothered by insects, you can use the Swat fly swatter, which sets the air in motion thanks to its rotating propeller strips, thereby repelling insects, wasps and flies and keeping them away from your food. The fly repeller can be placed on the table or hung up. The power supply works via USB cable, optionally also with two AA batteries (not included).
