Monitoring – Rodent Trap Selection

General Considerations

There are many types of rodent traps to choose from. Selecting the best type of trap for your application is important to the success of your monitoring program. Using an inappropriate trap style can mean fewer captures, lower efficiency in servicing traps, secondary infestation of rodent carcasses by insects, or an animal’s unnecessary pain and suffering. As a result, it may also impact the quality of your monitoring data. For example, rodents may avoid traps that are not positioned properly, or a placed outside of natural runways. On the other hand, using remote traps in locations that are difficult to access may reduce servicing time by allowing pest management professionals to focus on known captures and allow them to more efficiently record, clear, and reset traps.

No trap is perfect for all monitoring applications.  It is important to match the trap to the needs of a particular situation. Some considerations include:

  1. Presence of known or suspected runways
  2. Proximity to human disturbances (will the trap get bumped or kicked?)
  3. Visibility concerns
  4. Ease of access to the trap location for servicing
  5. Outdoor vs. indoor use
  6. The size or capacity of the trap
Glue Traps

Flat glue traps are sometimes used to trap rodents. These traps have a thicker glue layer (2 – 4 mm) than those needed to trap insects. Generally other methods such as snap traps or live traps are considered to be more humane for rodents because they are less likely to cause prolonged suffering.

Snap Traps

Snap traps are the preferred method of trapping mice.
