VEXING (ISI), was created and developed by President and CEO, Mary A. Paglieri.  It was first presented at the San Mateo County Coyote Forum in 1999.

 Little Blue Society uses VEXING (ISI), Integrated Stepwise Intervention, to modify the behavior of wildlife. 

Direct behavioral correction applied to wildlife and habitat modification (Intervention), and observation is applied in ascending Steps. Observation after each Stepwise Intervention dictates what corrective measures are further needed. With each ascending Step, the Intervention increases in intensity, until the desired behavior in wildlife is achieved.

Through our many years of experience and perfecting our VEXING (ISI) methodlogy, we have found that most aberrant behavior in (healthy) wildlife can be corrected, with exception to those animals that are sick, and lose the ability to forage.  At which  point, it would be our recommendation to humanely euthanize that animal.

At every Step of the Intervention, the “loop” needs to be closed, before moving up to the next Step.  Closing the loop means addressing all “hotspots” that are identified at each Step and making all the necessary/required changes to the environment in those areas.

VEXING (ISI) is not simply about applying direct correction to modify wildlife behavior.  It is about making the necessary changes to the environment in order to address the true underlying causes for wildlife to “misbehave.” If the attractant is not removed or modified, it won’t be long before any animal reverts back to the undesirable behavior, regardless of how much direct behavioral correction it has received. 

The Integration of other agencies and organizations to work together, as a team, to provide education to the public and whatever else is needed, is a crucial part of the VEXING (ISI) program.

·       VEXING (ISI), does not cause targeted wildlife to completely vacate the area. “Treated” wildlife may be seen from time to time, but with less frequency, and will not exhibit “bad behavior.”

·       The success of this Program, especially applied in larger geographical areas with many variables, is largely dependent on cooperation, precise communication and coordination/teamwork with all agencies involved.
