QuadBlaster QB - 4 - Ultrasonic Bird Repeller

Special Order from the USA, can take up to 14 business days!
$19.95 (Fixed shipping cost)

    Special Order from the USA, can take up to 14 business days!

    THE Quad Blaster QB-4has been specifically designed for large sheds, warehouses and storage places that pest birds sometimes get into for shelter and roosting.

    The QB-4 is designed to do a twofold job:

    1. Rout birds from firmly established Spatial Infestations by assailing them with an intolerable sound and once out,

    2. Keep birds out by forming a Perimeter Defence through which the birds will not want to re- enter the premises. The unit transmits ultra sonic (not audible) sound waves that annoy, irritate and confuse pest birds.  

    Target pests include: Pigeons, Sparrows, Starlings, Swallows,  Bats.

    This is a commercial grade product that should be mounted to roofs and ceilings to enable the best coverage. The 4 speakers allow the sound waves to cover most spots of your warehouse.

    The use of the variables: Frequency Mode Selection, Speaker Rotation Speed and Warble Rate create changing environments to repel roosting birds. Change is one of the best tools in the repelling of birds, as birds are creatures of habit and they do not grow accustomed to a dynamic environment.

    Can be left running 24 hours a day.

    PLEASE NOTE if humans are to be in constant proximity of speakers we recommend installing at a distance of 7 metres to not interfere with hearing!

    Ultra Sonic  coverage up to 600 sq. metres 

    Recommended for use indoors or in semi-enclosed spaces, such as:

    •Warehouses, plants, factories  
    •Hangars, railroad sidings, boat houses  
    •Tunnels, underpasses, breezeways
    •Sports arenas & convention centres
    •Sheds, storage buildings
    •Loading docks, parking garages, car washes .

    For severe bird infestations we recommend a Multi-sensory attack by adding our Strobe to the unit.

    Customers that currently use this product include the USA Armed forces, Coca Cola, Wrigley Field and locally LinFox Transport, BHP Billiton, Sonnoco Australia, PRC Agriculture, Grain Corp NSW, Waverly Council.

      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.
    –James S. from Sydney, Australia

       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. 

      Installation was simple and quick. We have not had birds in our hangar since we installed the QuadBlaster units. You have a really great product and the service/tech support was outstanding.


    All Birds Off products have been trialled and tested and do not harm birds. Products are not sold on a trial and return basis. Pls make your choice of bird deterrent carefully since there are many variables in consideration of bird control: environment; character and motivation of species; breeding or roosting cycle; hunger or tameness of the birds. Consider your overall strategy when preparing your deterrents. Sometimes , one or more products might be needed to increase bird control success rates.

      I had a little 6 horse stable where my babies would literally get
      pooed on daily by pigeons.
      My investment in the Quod Blaster was worth every cent.

      We purchased this product for our 3,800 Sq meter warehouse. It worked very well at expelling the birds after about 10 days or so. We installed it on the 12 meter high ceiling. Pretty easy to install.

    90 day Warranty against defects in materials and workmanship.

    We have supplied a range of our bird scarer products to the following brands for the past 16 years.
