Wide metal bands wrapped around tree trunks, known as tree collars or baffles, serve as chemical-free protective barriers.
These smooth devices prevent climbing animals like squirrels, raccoons, and rats from gaining traction on rough bark.

Without bark grip, animals cannot reach higher branches to strip fruit, build nests, or damage delicate bark.
Collars are typically installed four to six feet high to prevent animals from jumping over the barrier.
Homeowners use metal bands to stop pests from using tree branches as bridges to roofs, attics, and chimneys.

In gardens and orchards, baffles protect valuable fruit and nut crops from being eaten before harvest.
Usually made of aluminum or galvanized steel, these bands create a slick, harmless obstacle that animals simply slide down.
Available in shiny or bark-colored finishes, properly installed bands allow the tree trunk to grow naturally without restriction.
