  Works Great and safe for my kids. We had mice in our basement consistantly. We also have a 1 year old and a 3 year old, so I didn't want anything to hurt my boys. So this was great, I didn't have to worry about them getting hurt by it. And it worked so great too. Thanks for a great organic product! No more mice.

  Five Stars. Cleared our front stoop of all traces of rodent droppings (which has been a chronic problem).

  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.
