Flies love garbage as much they love their food. They are so annoying as they buzz around and ruin your fun moments. It’s disgusting that they are sitting in the garbage and sitting on your food while you on a nice picnic.
The garbage can fly trap attaches to any trash bin and makes flies a things of you don’t remember.
To use it, just drill a small hole on the top of whatever garbage container you have and there is a discharge button so you don’t want see old trashed flies. Basically the flies can enter to trash bin through this false hole, so they actually enter in to the trap.
