How to keep otters from denning under buildings

Eliminate access to convenient denning sites. Close potential entries under porches, houses, sheds, and other structures with ¼-1/2inch mesh welded wire (hardware cloth), boards, or other sturdy material.

Aluminum flashing, or aluminum or stainless-steel hardware cloth is recommended in saltwater areas since galvanized materials quickly corrode.

Laws and regulations to be aware of

While we attempt to provide guidance about state and federal regulations pertaining to specific species and control techniques, we do not provide information about local jurisdictions (city, town, county, etc.) where regulations may be more restrictive, especially as it applies to discharge of firearms, transport of animals or use of trapping equipment. Contact your local city or county government to inquire further. No guarantee is made that information (or lack of information) associated with a species or control technique is completely accurate or current. You should become familiar with federal, state and local laws before beginning any wildlife control activities.
