9. Fly Trapper

Flies fall squarely in the same category of “annoying” as mosquitoes. They carry germs and love to settle down on foods. Sure, you could go around swatting them (which seems near impossible with these suckers), or you could build a fly trap, sit back, and relax while the trap does the job for you. To do this, you’ll need a big container with a lid. Place a few banana peels inside, and hammer a few holes (large enough for a fly to get in) on the lid. The flies will go in but be too confused to get out.
