Housing for DOC 200 traps comes in two variants:
Traditional wooden housing. Widely accepted - made of natural materials and inconspicuous in the environment.
Newer plastic version is lighter, stackable and more conspicuous. This may be an issue in an environment with passing foot traffic.
DOC 200 trap options:
The Stainless Steel Trap is recommended for damp, humid or salty environments
The Combo Trap, with its stainless steel trigger but galvanised iron body is recommended for areas where a damp or salty atmosphere is not as common
