Step by Step
1. Wrap and staple fiberglass insulation around tree trunk
2. Cover insulation with household garbage bags
3. Use duct tape to secure garbage bag seam
4. Seal top and bottom of wrap with duct tape
5. Spread axle grease over surface of garbage bag wrap
Why This Isn't Ideal
1. Expensive to purchase all required components
2. Difficult to install and usually requires help
3. Not efficient and in some cases ineffective at doing its job
4. Not aesthetically pleasing in a yard or neighbourhood 
5. Can damage tree's health if band remains on tree after season
6. Will become waterlogged after rain which can cause bark rot
7. Not environmentally friendly materials to produce or dispose
