I had a number of my listeners with rodent problems test your product and the results were well above the standards I’ve set for products.  You probably wonder what that means, let me explain. When I test any product it must work better than 80% of the time.  In other words, if 10 people test the product, 8 or more must say it worked before I will recommend it to my listeners…I must say I’m happy to recommend Weiser’s Nature’s Defense to anybody with a rodent problem.

Add & Combine

For maximum, sustained success in your bird control efforts, a synergistic approach is recommended.  Synergy is the interaction of two or more forces producing a combined effect that is greater than the sum of their individual effects. We often recommend companion products – combining sonic repellent devices with visual scares or scent and taste aversions.  This kind of multi-sensory attack is extremely effective in deterring pest birds from an area permanently.
