Question 1

What is the minimum recommended gauge of hardware cloth for excluding raccoons?

Accepted Answer

14-gauge or heavier

Answer

14-gauge or heavier is required because raccoons have sufficient strength to tear lighter materials.

Question 2

How far should the horizontal footer of an L-shaped buried mesh barrier extend outward?

Accepted Answer

24 inches or more

Answer

A minimum 24-inch horizontal footer prevents burrowing animals from digging underneath the barrier.

Question 3

What type of one-way exclusion device is MOST appropriate for squirrels exiting a soffit opening?

Accepted Answer

A cone or funnel-shaped device with wire mesh tube
