  After trying other products with little or no resolve, we are finally rid of birds. We purchased a QuadBlaster from you in 2002 and our site staff are very pleased to see such great results. It started working on the first day of installation and after three months of monitoring the situation we have decided to purchase two more units for other areas of our facility.
–Dan from Linear Technology Corp.

  All attempts to remove pigeons have failed up until now. We installed three QuadBlasters four weeks ago at Edge Cinema when the infestation of pigeons had overrun a car park, balcony and front of our building for some years. Since installing the repellers, the pigeons have thankfully left the scene. Great results as there is no more constant cleaning of the terrible mess they constantly left behind or removing the birds which used to fly into the building itself. We are so pleased with the outcome! The product does a great job.

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 & taste aversions. This kind of multi-sensory attack is extremely effective in deterring pest birds from an area permanently.
